Description
BACKGROUND OF THE INVENTION
Technical Field
[0001] The present invention relates to a movable carrier auxiliary
system, and more particularly to an auxiliary system capable of
assisting vehicle parking by identifying environmental images.
Description of Related Art
[0002] With frequent commercial activities and the rapid expansion
of transportation logistics, people are more dependent on the
mobile vehicle such as car or motorcycle. At the same time, drivers
are paying more and more attention to the protection of their lives
and property when driving, and therefore, in addition to the
performance and the comfort of the mobile vehicle, it is also
considered whether the mobile vehicle to be purchased provides
sufficient safety guards or auxiliary devices. Under this trend, in
order to increase the safety of vehicles, automobile manufacturers
or vehicle equipment design manufacturers have developed various
driving safety protection devices or auxiliary devices, such as
rearview mirrors, driving recorders, a panoramic image instant
displaying of blind vision areas, a global positioning system that
records the driving path at any time, and etc.
[0003] In addition, with the rapid development of digital cameras
and computer visions in daily life, the digital cameras have been
applied to driving assistance systems, hoping to reduce the
accident rate of traffic accidents through the application of
artificial intelligence.
[0004] Typically, during a parking process, the driver observes a
condition outside the vehicle via rear-view mirrors on sides of the
vehicle or inside of the vehicle, thereby to determine a relative
position of the vehicle and a parking space so as to park the
vehicle. However, the condition outside the vehicle observed in the
rearview mirrors still has many blind spots that cannot be seen. In
addition, the front pillar, the center pillar, the rear pillar and
other structures of the vehicle will also block the driver's line
of sight, resulting in blind spots. For the problem of blind spots,
the driver can only park the vehicle by controlling the vehicle
based on experience, so that there are some drivers having
difficulty in parking the vehicle due to lack of experience,
inattention, or external environmental factors (such as weather and
brightness), which makes it difficult for the driver to park the
vehicle in the parking space, and may even clash other
vehicles.
BRIEF SUMMARY OF THE INVENTION
[0005] In view of the above, the purpose of the present invention
is to provide a movable carrier auxiliary system and a parking
auxiliary method thereof, which could improve a convenience and a

axis, to a point on the optical axis, where a projection of the
maximum effective semi diameter of the image-side surface of the
seventh lens ends, is denoted by InRS62 (the depth of the maximum
effective semi diameter). The depth of the maximum effective semi
diameter (sinkage) on the object-side surface or the image-side

[0035] An inflection point, a distance perpendicular to the optical
axis between the inflection point and the optical axis, and a
sinkage value thereof on the object-side surface or image-side
surface of other lenses is denoted in the same manner.
[0036] The lens parameter related to an aberration:
[0037] Optical distortion for image formation in the optical image
capturing system is denoted by ODT. TV distortion for image
formation in the optical image capturing system is denoted by TDT.
Further, the range of the aberration offset for the view of image
formation may be limited to 50%-100% field. An offset of the
spherical aberration is denoted by DFS. An offset of the coma
aberration is denoted by DFC.
[0038] The length of the contour curve of any surface of a single
lens in the range of the maximum effective radius affects the
surface correction aberration and the optical path difference
between the fields of view. The longer the profile curve length,
the better the ability to correct the aberration, but at the same
time It will increase the difficulty in manufacturing, so it is
necessary to control the length of the profile curve of any surface
of a single lens within the maximum effective radius, in particular
to control the profile length (ARS) and the surface within the
maximum effective radius of the surface. The proportional
relationship (ARS/TP) between the thicknesses (TP) of the lens on
the optical axis. For example, the length of the contour curve of
the maximum effective radius of the side surface of the first lens
object is represented by ARS11, and the thickness of the first lens
on the optical axis is TP1, and the ratio between the two is
ARS11/TP1, and the maximum effective radius of the side of the
first lens image side. The length of the contour curve is
represented by ARS12, and the ratio between it and TP1 is
ARS12/TP1. The length of the contour curve of the maximum effective
radius of the side of the second lens object is represented by
ARS21, the thickness of the second lens on the optical axis is TP2,
the ratio between the two is ARS21/TP2, and the contour of the
maximum effective radius of the side of the second lens image The
length of the curve is represented by ARS22, and the ratio between
it and TP2 is ARS22/TP2. The proportional relationship between the
length of the profile of the maximum effective radius of any
surface of the remaining lenses in the optical imaging system and
the thickness (TP) of the lens on the optical axis to which the
surface belongs, and so on.
[0039] The optical image capturing system has a maximum image
height HOI on the image plane vertical to the optical axis. A
transverse aberration at 0.7 HOI in the positive direction of the
tangential ray fan aberration after the longest operation
wavelength passing through the edge of the entrance pupil is
denoted by PLTA; a transverse aberration at 0.7 HOI in the positive
direction of the tangential ray fan aberration after the shortest
operation wavelength passing through the edge of the entrance pupil
is denoted by PSTA; a transverse aberration at 0.7 HOI in the
negative direction of the tangential ray fan aberration after the
longest operation wavelength passing through the edge of the
entrance pupil is denoted by NLTA; a transverse aberration at 0.7
HOI in the negative direction of the tangential ray fan aberration
after the shortest operation wavelength passing through the edge of
the entrance pupil is denoted by NSTA; a transverse aberration at
0.7 HOI of the sagittal ray fan aberration after the longest
operation wavelength passing through the edge of the entrance pupil
is denoted by SLTA; a transverse aberration at 0.7 HOI of the
sagittal ray fan aberration after the shortest operation wavelength
passing through the edge of the entrance pupil is denoted by
SSTA.
[0040] For any surface of any lens, the profile curve length within
a half the entrance pupil diameter (HEP) affects the ability of the
surface to correct aberration and differences between optical paths
of light in different fields of view. With longer profile curve
length, the ability to correct aberration is better. However, the
difficulty of manufacturing increases as well. Therefore, the
profile curve length within a half the entrance pupil diameter
(HEP) of any surface of any lens has to be controlled. The ratio
between the profile curve length (ARE) within a half the entrance
pupil diameter (HEP) of one surface and the thickness (TP) of the
lens, which the surface belonged to, on the optical axis (i.e.,
ARE/TP) has to be particularly controlled. For example, the profile
curve length of a half the entrance pupil diameter (HEP) of the
object-side surface of the first lens is denoted by ARE11, the
thickness of the first lens on the optical axis is TP1, and the
ratio between these two parameters is ARE11/TP1; the profile curve
length of a half the entrance pupil diameter (HEP) of the
image-side surface of the first lens is denoted by ARE12, and the
ratio between ARE12 and TP1 is ARE12/TP1. The profile curve length
of a half the entrance pupil diameter (HEP) of the object-side
surface of the second lens is denoted by ARE21, the thickness of
the second lens on the optical axis is TP2, and the ratio between
these two parameters is ARE21/TP2; the profile curve length of a
half the entrance pupil diameter (HEP) of the image-side surface of
the second lens is denoted by ARE22, and the ratio between ARE22
and TP2 is ARE22/TP2. For any surface of other lenses in the
optical image capturing system, the ratio between the profile curve
length of half the entrance pupil diameter (HEP) thereof and the
thickness of the lens which the surface belonged to is denoted in
the same manner.
[0041] The aspect of embodiment of the present disclosure further
directs to a parking auxiliary method of a movable carrier
auxiliary system, comprising following steps:
[0042] A. capture an environmental image around the movable carrier
with the image capturing module;

control the control device, improving the convenience and the
safety when parking the movable carrier.

DETAILED DESCRIPTION OF THE INVENTION
[0075] A movable carrier auxiliary system of the present invention
mainly includes a system design and an optical design, wherein
system embodiments will be described first.
[0076] Take FIG. 1A and FIG. 1B as an example to illustrate a
schematic view of a movable carrier auxiliary system 0001 according
to a first system embodiment of the present invention, wherein the
movable carrier auxiliary system 0001 includes an environmental
detecting device 0010, a control device 0020, a state detecting
device 0030, and a parking auxiliary device 0040.
[0077] The environmental detecting device 0010 includes an image
capturing module 0011 and an operation module 0013. As shown in
FIG. 1C, the image capturing module 0011 is disposed in the movable
carrier 0000 and is adapted to capture an environmental image
around the movable carrier 0000. In the current embodiment, the
image capturing module 0011 includes a lens group and an image
sensing component, wherein the lens group includes at least two
lenses having refractive power for imaging to the image sensing
component to generate the environmental image. The conditions of
the lens group will be described in the optical embodiments.
Referring to FIG. 1C, the image capturing module 0011 is disposed
on a right side of the movable carrier 0000 as an example, wherein
the right side could be a right rear-view mirror. In an embodiment,
the image capturing module 0011 could be disposed on a left side of
the movable carrier 0000, for example, wherein the left side could
be a left rear-view mirror.
[0078] In the current embodiment, the environmental detecting
device 0010 further includes a luminance sensor 0012 electrically
connected to the image capturing module 0011 for detecting the
luminance on at least a direction in which the image capturing
module 0011 captures the image. When the luminance measured by the
luminance sensor 0012 is greater than an upper threshold, the image
capturing module 0011 captures the environmental image in a way
that reduces amount of light entering. When the luminance measured
by the luminance sensor 0012 is less than a lower threshold, the
image capturing module 0011 captures the environmental image in a
way that increases the amount of light entering. In this way, an
environmental image with appropriate luminance could be obtained,
avoiding overexposure or underexposure.
[0079] The operation module 0013 is electrically connected to the
image capturing module 0011 for receiving the environmental image
and determines whether the environmental image has a parking space
000A or not, wherein a capacity of the parking space 000A is
greater than a volume of the movable carrier 0000, and a length, a
width, and a height of the parking space 000A is greater than a
length, a width, and a height of the movable carrier 0000. More
specifically, the operation module 0013 stores data of the length,
the width, and the height of the movable carrier 0000 as a
benchmark for determining the parking space 000A. The operation
module 0013 determines a distance between the movable carrier 0000
and the parking space 000A and a relative position of the movable
carrier 0000 and the parking space 000A via the environmental
image.
[0080] In practice, the image capturing module 0011 could include
two image capturing modules 0011, wherein depth of fields of the
environmental images captured by the two image capturing modules
0011 are different. The operation module 0013 is electrically
connected to the image capturing module 0011 determines whether
there is a parking space 000A or not and determines the distance
between the movable carrier 0000 and the parking space 000A and the
relative position of the movable carrier 0000 and the parking space
000A via a three-dimensional environmental image formed by the
environmental images captured by the two image capturing modules
0011.
[0081] The control device 0020 is disposed in the movable carrier
0000 for being manipulated by a driver to move the movable carrier
0000, and includes a steering wheel 0021, a gear shift module 0022,
a driving pedal 0023, and a braking pedal 0024.
[0082] The state detecting device 0030 is disposed in the movable
carrier 0000 for detecting a movement state of the movable carrier
0000. Referring to FIG. 1B, the state detecting device 0030 at
least includes a speed sensor 0031 for detecting a speed of the
movable carrier 0000. The movement state at least includes the
speed of the movable carrier 0000. The state detecting device 0030
could further include at least one of a steering angle sensor 0032
and an inertial sensor 0033, wherein the steering angle sensor 0032
is adapted to detect a steering angle of the movable carrier 0000,
and the inertial sensor 0033 is adapted to detect an acceleration,
an inclination angle, or a yaw rate of the movable carrier 0000.
The movement state could include a detecting result of at least one
of the steering angle sensor 0032 and the inertial sensor 0033.
[0083] The parking auxiliary device 0040 is disposed in the movable
carrier 0000 and is electrically connected to the operation module
0013 of the environmental detecting device 0010, the state
detecting device 0030, and the control device 0020. When the
environmental image has the parking space 000A, the parking
auxiliary device 0040 generates a prompting message based on the
distance between the movable carrier 0000 and the parking space
000A, the relative position of the movable carrier 0000 and the
parking space 000A, and the movement state of the movable carrier
0000, so that the driver could control the control device 0020 to
move the movable carrier 0000 to the parking space 000A based on
the prompting message. In the current embodiment, the parking
auxiliary device 0040 generates the prompting message based on the
distance between the movable carrier 0000 and the parking space
000A, the relative position of the movable carrier 0000 and the
parking space 000A, and the speed, the steering angle, the
acceleration, the inclination angle, and the yaw rate of the
movable carrier 0000.
[0084] The parking auxiliary device 0040 generates the prompting
message which corresponds to a steering direction and a steering
margin, and corresponds to a gear position of the gear shift module
0022, and corresponds to whether the driving pedal 0023 is pedaled
or not, and corresponds to whether the braking pedal 0024 is
pedaled or not, so that the driver could control the steering wheel
0021, the gear shift module 0022, the driving pedal 0023, and the
braking pedal 0024 based on the prompting message to move the
movable carrier 0000 to the parking space 000A.
[0085] In an embodiment, the parking auxiliary device 0040 could
automatically control the steering wheel 0021 to rotate, and could
generates the prompting message which corresponds to the gear
position of the gear shift module 0022, and corresponds to whether
the driving pedal 0023 is pedaled or not, and corresponds to
whether the braking pedal 0024 is pedaled or not. In this way, the
driver could park the movable carrier 0000 without controlling the
steering wheel 0021.
[0086] In an embodiment, the parking auxiliary device 0040 could
automatically control the steering wheel 0021 to rotate, and could
automatically control the operations of the driving pedal 0023 and
the braking pedal 0024, and could generates the prompting message
which corresponds to the gear position of the gear shift module
0022. In this way, all the driver has to do during the parking
process is to control the gear shift module 0022 to be a forward
gear or a reverse gear.
[0087] In order to increase the safety during the parking process,
when the parking auxiliary device 0040 determines that a movement
speed of the movable carrier 0000 measured by the speed sensor 031
of the state detecting device 0030 is less than or equal to a
starting speed, the parking auxiliary device 0040 generates the
prompting message. When the movement speed of the movable carrier
0000 measured by the speed sensor 031 is greater than the starting
speed, the parking auxiliary device 0040 does not generate the
prompting message, thereby to prevent the driver from not having
sufficient time to react.
[0088] In the current embodiment, the operation module 0013 could
further determine whether the environmental image has an
obstruction 000B located between the movable carrier 0000 and the
parking space 000A. The parking auxiliary device 0040 further
includes a warning module 0041, wherein when the driver controls
the control device 0020 based on the prompting message and the
environmental image has the obstruction 000B located between the
movable carrier 0000 and the parking space 000A (as shown in FIG.
1D), the warning module 0041 generates a warning message. The
warning module 0041 at least includes one of a voice playback
member 004a, a light generating member 004b, and an image
displaying member 004c, thereby to present the warning message in
forms of sounds, lights, or both of sounds and lights, or
displaying an image or a text, or both of the image and the
text.
[0089] In an embodiment, the parking auxiliary device 0040 at least
includes the voice playback member 004a, wherein the warning
message is presented by playing a corresponding voice of the
warning message via the voice playback member 004a.
[0090] In addition to determining the parking space 000A via the
environmental image, the environmental detecting device 0010
further includes a detection wave transceiver module 0014
electrically connected to the operation module 0013. The detection
wave transceiver module 0014 sends a detection wave in at least a
direction which is not a traveling direction of the movable carrier
0000 (e.g. a rightward direction of the movable carrier 0000), and
receives a reflection detection wave of the detection wave, wherein
the detection wave could be ultrasonic wave, millimeter wave radar,
lidar, infrared light, laser, or a combination of the foregoing.
The operation module 0013 further determines whether the
environmental image has the parking space 000A or not via the
reflection detection wave and the environmental image, thereby to
determine a correctness of the parking space 000A via the
environmental image and the reflection detection wave.
[0091] Additionally, the detection wave transceiver module 0014
could also send a detection wave in a traveling direction of the
movable carrier 0000 (e.g. a frontward or a backward direction of
the movable carrier 0000), and receives a reflection detection wave
of the detection wave. The operation module 0013 determines the
distance between the movable carrier 0000 and the parking space
000A and the relative position of the movable carrier 0000 and the
parking space 000A via the reflection detection wave and the
environmental image, thereby to determine a correctness of the
distance between the movable carrier 0000 and the parking space
000A and the relative position of the movable carrier 0000 and the
parking space 000A via the environmental image and the reflection
detection wave.
[0092] The parking auxiliary device 0040 further includes a
displaying module 0042 electrically connected to the environmental
detecting device 0010, wherein the prompting message is displayed
on the displaying module 0042 as an image, a text, or both of the
image and the text.
[0093] FIG. 1E is a schematic perspective view showing the
displaying module 0042 according to the first system embodiment of
the present invention, in which the displaying module 0042 is a
vehicle electronic rear-view mirror 0100 having a display (not
shown), for example. FIG. 1F is a schematic section view taken
along the short side of the displaying module of FIG. 1E. The
vehicle electronic rear-view mirror 0100 could be disposed on a
movable carrier, e.g. a vehicle, to assist in the driving of the
vehicle or to provide information about driving. More specifically,
the vehicle electronic rear-view mirror 0100 could be an inner
rear-view mirror disposed inside the vehicle or an outer rear-view
mirror disposed outside the vehicle, both of which are used to
assist the driver in understanding the location of other vehicles.
However, this is not a limitation on the present invention. In
addition, the movable carrier is not limited to the vehicle, and
could be other types of transportation, such as a land train, an
aircraft, a water ship, etc.
[0094] The vehicle electronic rear-view mirror 0100 is assembled in
a casing 0110, wherein the casing 0110 has an opening (not shown).
More specifically, the opening of the casing 0110 overlaps with a
reflective layer 0190 of the vehicle electronic rear-view mirror
0100. In this way, external light could be transmitted to the
reflective layer 0190 located inside the casing 0110 through the
opening, so that the vehicle electronic rear-view mirror 0100
functions as a mirror. When the driver drives the vehicle and faces
the opening, for example, the driver could perceive the external
light reflected by the vehicle electronic rear-view mirror 0100,
thereby knowing the position of the rear vehicle.
[0095] Referring to FIG. 1F, the vehicle electronic rear-view
mirror 0100 includes a first transparent assembly 0120 and a second
transparent assembly 0130, wherein the first transparent assembly
0120 faces the driver, and the second transparent assembly 0130 is
disposed on a side away from the driver. More specifically, the
first transparent assembly 0120 and the second transparent assembly
0130 are translucent substrates, wherein a material of the
translucent substrates could be glass, for example. However, the
material of the translucent substrates is not a limitation on the
present invention. In other embodiments, the material of the
translucent substrates could be plastic, quartz, PET substrate, or
other applicable materials, wherein the PET substrate has the
advantages of low cost, easy manufacture, and extremely thinness,
in addition to the packaging and protection effects.
[0096] In this embodiment, the first transparent assembly 0120
includes a first incidence surface 0122 and a first exit surface
0124, wherein an incoming light image from the rear of the driver
enters the first transparent assembly 0120 via the first incidence
surface 0122, and is emitted via the first exit surface 0124. The
second transparent assembly 0130 includes a second incidence
surface 0132 and a second exit surface 0134, wherein the second
incidence surface 0132 faces the first exit surface 0124, and a gap
is formed between the second incidence surface 0132 and the first
exit surface 0124 by an adhesive 0114. After being emitted via the
first exit surface 0124, the incoming light image enters the second
transparent assembly 0130 via the second incidence surface 0132 and
emitted via the second exit surface 0134.
[0097] An electro-optic medium layer 0140 is disposed in the gap
between the first exit surface 0124 of the first transparent
assembly 0120 and the second incidence surface 0132 of the second
transparent assembly 0130. At least one transparent electrode 0150
is disposed between the first transparent assembly 0120 and the
electro-optic medium layer 0140. The electro-optic medium layer
0140 is disposed between the first transparent assembly 0120 and at
least one reflective layer 0190. A transparent conductive layer
0160 is disposed between the first transparent assembly 0120 and
the electro-optic medium layer 0140. Another transparent conductive
layer 0160 is disposed between the second transparent assembly 0130
and the electro-optic medium layer 0140. An electrical connector
0170 is electrically connected to the transparent conductive layer
0160, and another electrical connector 0170 is electrically
connected to the transparent electrode 0150, which is electrically
connected to the electro-optic medium layer 0140 directly or
indirectly through the another transparent conductive layer 0160,
thereby transmitting electrical energy to the electro-optic medium
layer 0140 to change a transparency of the electro-optic medium
layer 0140. When a luminance of the incoming light image exceeds a
certain luminance (e.g. strong light from the headlight of the rear
vehicle), a glare sensor 0112 electrically connected to a control
member 0180 receives the light energy and convert it into a signal,
and the control member 0180 determines whether the luminance of the
incoming light image exceeds a predetermined luminance, and if a
glare is generated, the electrical energy is provided to the
electro-optic medium layer 0140 by the electrical connector 0170 to
generate an anti-glare performance Generally, if the incoming light
image has a strong luminance, the glare could be generated and thus
affects the driver's line of sight, thereby endangering the driving
safety.
[0098] In addition, the transparent electrode 0150 and the
reflective layer 0190 could respectively cover the entire surfaces
of the first transparent assembly 0120 and the second transparent
assembly 0130. However, this is not a limitation on the present
invention. In this embodiment, the transparent electrode 0150 could
use a material selected from metal oxides, such as indium tin
oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide,
indium antimony zinc oxide, or other suitable oxides, or a stacked
layer composed of at least two of the foregoing oxides. Moreover,
the reflective layer 0190 could be conductive and made of a
material selected from the group consisting of silver (Ag), copper
(Cu), aluminum (Al), titanium (Ti), chromium (Cr), molybdenum (Mo),
and an alloy thereof, or contains silicon dioxide or a transparent
conductive material. However, the material of the transparent
electrode 0150 and the material of the reflective layer 0190 are
not limitations on the present invention. In other embodiments, the
material of the transparent electrode 0150 and the material of the
reflective layer 0190 could be other types of materials.
[0099] The electro-optic medium layer 0140 could be made of an
organic material or an inorganic material. However, this is not a
limitation on the present invention. In the current embodiment, the
electro-optic medium layer 0140 could be an electrochromic
material. The electro-optic medium layer 0140 is disposed between
the first transparent assembly 0120 and the second transparent
assembly 0130 and also disposed between the first transparent
assembly 0120 and the reflective layer 0190. More specifically, the
transparent electrode 0150 is disposed between the first
transparent assembly 0120 and the electro-optic medium layer 0140
(i.e., the electrochromic material layer). In an embodiment, the
reflective layer 0190 could be disposed between the second
transparent assembly 0130 and the electro-optic medium layer 0140.
In addition, in the current embodiment, the vehicle electronic
rear-view mirror 0100 further includes an adhesive 0114 located
between the first transparent assembly 0120 and the second
transparent assembly 0130 and surrounding the electro-optic medium
layer 0140. The electro-optic medium layer 0140 is co-packaged by
the adhesive 0114, the first transparent assembly 0120, and the
second transparent assembly 0130.
[0100] In the current embodiment, the transparent conductive layer
0160 is disposed between the electro-optic medium layer 0140 and
the reflective layer 0190. More specifically, the transparent
conductive layer 0160 could be used as an anti-oxidation layer of
the reflective layer 0190, so that the electro-optic medium layer
0140 could be prevented from direct contact with the reflective
layer 0190, thereby preventing the reflective layer 0190 from being
corroded by the organic materials, and extending the service life
of the vehicle electronic rear-view mirror 0100 of the current
embodiment. In addition, the electro-optic medium layer 0140 is
co-packaged by the adhesive 0114, the transparent electrode 0150,
and the transparent conductive layer 0160. In the current
embodiment, the transparent conductive layer 0160 contains a
material selected from the group consisting of indium tin oxide
(ITO), indium zinc oxide (IZO), Al-doped ZnO (AZO), fluorine-doped
tin oxide, and a combination thereof.
[0101] In the current embodiment, the vehicle electronic rear-view
mirror 0100 could be optionally provided with the electrical
connector 0170. For instance, in an embodiment, the electrical
connector 0170 could be a conducting wire or a conducting structure
electrically connected to the transparent electrode 0150 and the
reflective layer 0190, so that the transparent electrode 0150 and
the reflective layer 0190 could be electrically connected to the at
least one control member 0180, which provides a driving signal via
the conducting wire or the conducting structure, thereby driving
the electro-optic medium layer 0140.
[0102] When the electro-optic medium layer 0140 is enabled, the
electro-optic medium layer 0140 would undergo an electrochemical
redox reaction and change its energy level to be in a diming state.
When external light passes through the opening of the casing 0110
and reaches the electro-optic medium layer 0140, the external light
would be absorbed by the electro-optic medium layer 0140 which is
in the diming state, so that the vehicle electronic rear-view
mirror 0100 is switched to an anti-glare mode. On the other hand,
when the electro-optic medium layer 0140 is disenabled, the
electro-optic medium layer 0140 is transparent. At this time, the
external light passing through the opening of the casing 0110
passes through the electro-optic medium layer 0140 to be reflected
by the reflective layer 0190, so that the vehicle electronic
rear-view mirror 0100 is switched to a mirror mode.
[0103] More specifically, the first transparent assembly 0120 has
the first incidence surface 0122 which is away from the second
transparent assembly 0130. For instance, external light from the
rear vehicles enters the vehicle electronic rear-view mirror 0100
via the first incidence surface 0122, and then the vehicle
electronic rear-view mirror 0100 reflects the external light such
that the external light leaves the vehicle electronic rear-view
mirror 0100 via the first incidence surface 0122. In addition, eyes
of the vehicle driver could receive the external light reflected by
the vehicle electronic rear-view mirror 0100 to know the position
of other vehicles behind. Moreover, the reflective layer 0190 could
have the optical property of partial transmission and partial
reflection by selecting a suitable material and designing a proper
film thickness.
[0104] The display of the vehicle electronic rear-view mirror 0100
could be an LCD or an LED, and the display could be disposed inside
or outside the casing 0110, for example, on the side of the second
transparent assembly 0130 away from the first transparent assembly
0120, or on the second exit surface 0134 of the second transparent
assembly 0130 away from the first transparent assembly 0120. Since
the reflective layer 0190 has the optical property of partial
transmission and partial reflection, the image light emitted by the
display could pass through the reflective layer 0190, thereby
allowing the user to view the internal image displayed by the
display so as to display the warning message.
[0105] With the aforementioned movable carrier auxiliary system, a
parking auxiliary method illustrated in FIG. 1G which includes
following steps could be executed.
[0106] Step S1: the image capturing module 0011 captures an
environmental image around the movable carrier 0000.
[0107] Step S2: the operation module 0013 receives the
environmental image and analyzes whether the environmental image
has a space with a capacity greater than a volume of the movable
carrier 0000, and a length, a width, and a height of the space is
greater than a length, a width, and a height of the movable
carrier; if there is the space with the capacity greater than the
volume of the movable carrier in the environmental image, and the
length, the width, and the height of the space is greater than the
length, the width, and the height of the movable carrier, the
operation module 0013 determines the space is the parking space
000A.
[0108] A plurality of determining ways which could be applied to
the operation module 0013 are provided followed, so that the
operation module 0013 in step S2 could determine the environmental
image has the parking space 000A.
[0109] (1) Referring to FIG. 1C, the operation module 0013 first
determines whether the environmental image has a parking grid
marking 000C. If there is the parking grid marking 000C in the
environmental image, the operation module 0013 determines whether
an area within the parking grid marking 000C has the parking space
000A or not.
[0110] (2) Referring to FIG. 1H, the operation module 0013 first
analyzes whether the environmental image has a line image forming a
plurality of corners 000D, and selects and determines the line
image with two corners 000D as the parking grid marking 000C, and
then determines whether an area between the two corners 000D has
the parking space 000A or not. The two selected corners 000D could
be adjacent corners 000D or diagonally opposite corners 000D. The
environment shown in FIG. 1C could also apply the way (2) to
determine the parking space 000A with the plurality of corners
000D.
[0111] (3) Referring to FIG. 1H, the operation module 0013 first
analyzes whether the environmental image has a line image forming a
plurality of corners 000D, and selects the line image with two
adjacent corners 000D, and determines whether there is a line
marking 000E between the two adjacent corners 000D or not. If there
is the line marking 000E between the two adjacent corners 000D, the
line image with two corners 000D is selected and determined as the
parking grid marking 000C, and then the operation module 0013
determines whether an area surrounded by the two adjacent corners
000D and the line marking 000E has the parking space 000A or not.
The environment shown in FIG. 1C could also apply the way (3) to
determine the parking space 000A with the plurality of corners 000D
and one of lines of the parking grid marking 000C (i.e., the line
marking 000E).
[0112] (4) Referring to FIG. 1I, the image capturing module 0011 is
disposed on a backside of the movable carrier 0000 as an example
for capturing an environmental image on a rearward of the movable
carrier 0000, wherein the backside of the movable carrier 0000
could be, for example, around a trunk of the movable carrier 0000
or on a rear bumper. The operation module 0013 first determines
whether the environmental image has two shunned carriers 000F. If
the environmental image has the two shunned carriers 000F, the
operation module 0013 determines whether an area between the two
shunned carriers 000F has the parking space 000A or not. If the
area between the two shunned carriers 000F has the parking space
000A, the operation module 0013 determines whether one of the
shunned carriers 000F moves or not, wherein the warning message is
generated when one of the shunned carriers 000F is determined
moves.
[0113] An environment shown in FIG. 1J could also apply the way (4)
to determine the parking space 000A.
[0114] An environment shown in FIG. 1K which has both of the
parking grid marking 000C and the shunned carriers 000F could also
apply one of the ways (1) to (4) to determine the parking space
000A.
[0115] Referring to FIG. 1L, the image capturing module 0011 is
disposed on a front side of the movable carrier 0000 as an example
for capturing and generating the environmental image which is in
front of the movable carrier 0000. The front side of the movable
carrier 0000 could be, for example, a side of a head of a vehicle,
a vicinity of the front windshield inside the vehicle, or a side of
the front bumper. An environment shown in FIG. 1L which has both of
the parking grid marking 000C and the shunned carriers 000F could
also apply one of the ways (1) to (4) to determine the parking
space 000A.
[0116] Step S3: the operation module 0013 determines the distance
between the parking space 000A and the movable carrier 0000 and the
relative position of the parking space 000A and the movable carrier
0000 via the environmental image.
[0117] Step S4: the state detecting device 0030 detects the
movement state of the movable carrier 0000, wherein the movement
state at least includes the speed of the movable carrier 0000.
[0118] Step S5: the parking auxiliary device 0040 generates the
prompting message by deriving based on the distance between the
parking space 000A and the movable carrier 0000 and the relative
position of the parking space 000A and the movable carrier 0000
obtained in step S3 and the movement state obtained in step S4,
thereby the driver could manipulate the control device 0020 based
on the prompting message to move the movable carrier 0000 to the
parking space 000A. In the current embodiment, when the movement
speed of the movable carrier 0000 measured by the state detecting
device 0030 is less than or equal to the starting speed, the
parking auxiliary device 0040 generates the prompting message.
[0119] Referring to FIG. 1D, when the driver manipulates the
control device 0020 based on the prompting message and when there
is the obstruction 000B located between the movable carrier 0000
and the parking space 000A in the environmental image, the parking
auxiliary device 0040 generates the warning message.
[0120] FIG. 1M illustrates a movable carrier 0002 according to a
second system embodiment of the present invention. FIG. 1N is a
block diagram showing the movable carrier auxiliary system 0003
according to the second system embodiment.
[0121] The movable carrier auxiliary system 0003 according to the
second system embodiment has almost the same structure with that of
the first system embodiment, except that the environmental
detecting device 0010 includes four image capturing modules 0011
and four luminance sensors 0012, wherein the image capturing
modules 0011 are respectively disposed on a front side, a backside,
a left side, and a right side of the movable carrier 0002 for
capturing environmental images on a frontward, a rearward, a
leftward, and a rightward of the movable carrier 0002.
[0122] The operation module 0013 detects whether an environmental
image spliced by the environmental images that the four image
capturing modules 0011 capture has the parking space 000A. A
horizontal angle of view covered by the environmental image spliced
by the environmental images that the four image capturing modules
0011 capture is 360 degrees. The environmental image spliced by the
environmental images that the image capturing modules 0011 capture
could be spliced by the operation module 0013. The movable carrier
auxiliary system 0003 according to the second system embodiment
could also apply the parking auxiliary method of the first system
embodiment, thus we are not going to describe it in details
herein.
[0123] However, the number of the image capturing module 0011 is
not a limitation of the present invention. In other embodiments,
the number of the image capturing module 0011 could be two, three,
or more than five.
[0124] Furthermore, the optical embodiments will be described in
detail as follows. The optical image capturing system could work
with three wavelengths, including 486.1 nm, 587.5 nm, and 656.2 nm,
wherein 587.5 nm is the main reference wavelength and is also the
reference wavelength for extracting the technical characteristics.
The optical image capturing system could also work with five
wavelengths, including 470 nm, 510 nm, 555 nm, 610 nm, and 650 nm,
wherein 555 nm is the main reference wavelength and is also the
reference wavelength for extracting the technical
characteristics.
[0125] The optical image capturing system of the present invention
satisfies 0.5.ltoreq..SIGMA.PPR/|.SIGMA.NPR|.ltoreq.15, and
preferably satisfies 1.ltoreq..SIGMA.PPR/|.SIGMA.NPR|.ltoreq.3.0,
where PPR is a ratio of the focal length f of the optical image
capturing system to a focal length fp of each of the lenses with
positive refractive power; NPR is a ratio of the focal length f of
the optical image capturing system to a focal length fn of each of
the lenses with negative refractive power; .SIGMA.PPR is a sum of
the PPRs of each positive lens; and .SIGMA.NPR is a sum of the NPRs
of each negative lens. It is helpful for control of an entire
refractive power and an entire length of the optical image
capturing system.
[0126] The optical image capturing system further includes an image
sensor provided on the image plane. The optical image capturing
system of the present invention satisfies HOS/HOI.ltoreq.50 and
0.5.ltoreq.HOS/f.ltoreq.150, and preferably satisfies
1.ltoreq.HOS/HOI.ltoreq.40 and 1.ltoreq.HOS/f.ltoreq.140, where HOI
is half a length of a diagonal of an effective sensing area of the
image sensor, i.e., the maximum image height, and HOS is a distance
in parallel with the optical axis between an object-side surface of
the first lens and the image plane of the at least one lens group.
It is helpful for the miniaturization of the optical image
capturing system and the application in light, thin, and portable
electronic products.
[0127] The optical image capturing system of the present invention
is further provided with an aperture to increase image quality.
[0128] In the optical image capturing system of the present
invention, the aperture could be a front aperture or a middle
aperture, wherein the front aperture is provided between the object
and the first lens, and the middle aperture is provided between the
first lens and the image plane. The front aperture provides a
relatively long distance between an exit pupil of the optical image
capturing system and the image plane, which allows more optical
elements to be installed and increases the image receiving
efficiency of the image sensor. The middle aperture could enlarge
the view angle of the optical image capturing system, which
provides the advantage of a wide-angle lens. The optical image
capturing system satisfies 0.1.ltoreq.InS/HOS.ltoreq.1.1, where InS
is a distance on the optical axis between the aperture and an image
plane of the at least one lens group. It is helpful for size
reduction and wide angle.
[0129] The optical image capturing system of the present invention
satisfies 0.1.ltoreq..SIGMA.TP/InTL.ltoreq.0.9, where InTL is a
distance in parallel with the optical axis from the object-side
surface of the first lens to an image-side surface of the sixth
lens, and .SIGMA.TP is a sum of central thicknesses of the lenses
having refractive power on the optical axis. It is helpful for the
contrast of image and yield rate of lens manufacturing, and also
provides a suitable back focal length for installation of other
elements.
[0130] The optical image capturing system of the present invention
satisfies 0.001.ltoreq.|R1/R2|.ltoreq.25, and preferably satisfies
0.01.ltoreq.|R1/R2|<12, where R1 is a radius of curvature of the
object-side surface of the first lens, and R2 is a radius of
curvature of the image-side surface of the first lens. It provides
the first lens with a suitable positive refractive power to reduce
the increase rate of the spherical aberration.
[0131] The optical image capturing system of the present invention
satisfies -7<(R11-R12)/(R11+R12)<50, where R11 is a radius of
curvature of the object-side surface of the sixth lens, and R12 is
a radius of curvature of the image-side surface of the sixth lens.
It may modify the astigmatic field curvature.
[0132] The optical image capturing system of the present invention
satisfies IN12/f.ltoreq.60, where IN12 is a distance on the optical
axis between the first lens and the second lens. It may correct
chromatic aberration and improve the performance.
[0133] The optical image capturing system of the present invention
satisfies IN56/f.ltoreq.3.0, where IN56 is a distance on the
optical axis between the fifth lens and the sixth lens. It may
correct chromatic aberration and improve the performance.
[0134] The optical image capturing system of the present invention
satisfies 0.1.ltoreq.(TP1+IN12)/TP2.ltoreq.10, where TP1 is a
central thickness of the first lens on the optical axis, and TP2 is
a central thickness of the second lens on the optical axis. It may
control the sensitivity of manufacture of the optical image
capturing system and improve the performance.
[0135] The optical image capturing system of the present invention
satisfies 0.1.ltoreq.(TP6+IN56)/TP5.ltoreq.15, where TP5 is a
central thickness of the fifth lens on the optical axis, TP6 is a
central thickness of the sixth lens on the optical axis, and IN56
is a distance between the fifth lens and the sixth lens. It may
control the sensitivity of manufacture of the optical image

[0146] In an embodiment, the lenses of high Abbe number and the
lenses of low Abbe number are arranged in an interlaced arrangement
that could be helpful for correction of aberration of the optical
image capturing system.
[0147] An equation of aspheric surface is
z=ch.sup.2/[1+[1(k+1)c.sup.2h.sup.2].sup.0.5]+A4h.sup.4.+-.A6h.sup.6+A8h-
.sup.8+A10h.sup.10+A12h.sup.12+A14h.sup.14+A16h.sup.16+A18h.sup.18+A20h.su-
p.20+ (1)
[0148] where z is a depression of the aspheric surface; k is conic
constant; c is reciprocal of the radius of curvature; and A4, A6,
A8, A10, A12, A14, A16, A18, and A20 are high-order aspheric
coefficients.
[0149] In the optical image capturing system, the lenses could be
made of plastic or glass. The plastic lenses may reduce the weight
and lower the cost of the optical image capturing system, and the
glass lenses may control the thermal effect and enlarge the space
for arrangement of the refractive power of the optical image
capturing system. In addition, the opposite surfaces (object-side
surface and image-side surface) of the first to the seventh lenses
could be aspheric that could obtain more control parameters to
reduce aberration. The number of aspheric glass lenses could be
less than the conventional spherical glass lenses, which is helpful
for reduction of the height of the optical image capturing
system.
[0150] Furthermore, in the optical image capturing system provided
by the present invention, when the lens has a convex surface, it
means that the surface of the lens around the optical axis is
convex, and when the lens has a concave surface, it means that the
surface of the lens around the optical axis is concave.
[0151] The optical image capturing system of the present invention
could be applied in a dynamic focusing optical image capturing
system. It is superior in the correction of aberration and high
imaging quality so that it could be allied in lots of fields.
[0152] The optical image capturing system of the present invention
could further include a driving module to meet different demands,
wherein the driving module could be coupled with the lenses to move
the lenses. The driving module could be a voice coil motor (VCM),
which is used to move the lens for focusing, or could be an optical
image stabilization (OIS) component, which is used to lower the
possibility of having the problem of image blurring which is caused
by subtle movements of the lens while shooting.
[0153] To meet different requirements, at least one lens among the
first lens to the seventh lens of the optical image capturing
system of the present invention could be a light filter, which
filters out light of wavelength shorter than 500 nm. Such effect
could be achieved by coating on at least one surface of the lens,
or by using materials capable of filtering out short waves to make
the lens.
[0154] To meet different requirements, the image plane of the
optical image capturing system in the present invention could be
either flat or curved. If the image plane is curved (e.g., a sphere
with a radius of curvature), the incidence angle required for
focusing light on the image plane could be decreased, which is not
only helpful to shorten the length of the optical image capturing
system (TTL), but also helpful to increase the relative
illuminance.
[0155] We provide several optical embodiments in conjunction with
the accompanying drawings for the best understanding. In practice,
the optical embodiments of the present invention could be applied
to other embodiments.

[0215] The detailed data of FIG. 2B of the first optical embodiment
are listed in Table 1, in which the unit of the radius of
curvature, thickness, and focal length are millimeter, and surface
0-16 indicates the surfaces of all elements in the system in
sequence from the object side to the image side. Table 2 is the
list of coefficients of the aspheric surfaces, in which k indicates
the taper coefficient in the aspheric curve equation, and A1-A20
indicate the coefficients of aspheric surfaces from the first order
to the twentieth order of each aspheric surface. The following
optical embodiments have similar diagrams and tables, which are the
same as those of the first optical embodiment, so we do not
describe it again. The definitions of the mechanism component
parameters of the following optical embodiments are the same as
those of the first optical embodiment.
Second Optical Embodiment
[0216] As shown in FIG. 3A and FIG. 3B, an optical image capturing
system 20 of the second optical embodiment of the present invention
includes, along an optical axis from an object side to an image
side, a first lens 210, a second lens 220, a third lens 230, an
aperture 200, a fourth lens 240, a fifth lens 250, a sixth lens
260, a seventh lens 270, an infrared rays filter 280, an image
plane 290, and an image sensor 292.
[0217] The first lens 210 has negative refractive power and is made
of glass. An object-side surface 212 thereof, which faces the
object side, is a convex spherical surface, and an image-side
surface 214 thereof, which faces the image side, is a concave
spherical surface.
[0218] The second lens 220 has negative refractive power and is
made of glass. An object-side surface 222 thereof, which faces the
object side, is a concave spherical surface, and an image-side
surface 224 thereof, which faces the image side, is a convex
spherical surface.
[0219] The third lens 230 has positive refractive power and is made
of glass. An object-side surface 232, which faces the object side,
is a convex spherical surface, and an image-side surface 234, which
faces the image side, is a convex spherical surface.
[0220] The fourth lens 240 has positive refractive power and is
made of glass. An object-side surface 242, which faces the object
side, is a convex spherical surface, and an image-side surface 244,
which faces the image side, is a convex spherical surface.
[0221] The fifth lens 250 has positive refractive power and is made
of glass. An object-side surface 252, which faces the object side,
is a convex spherical surface, and an image-side surface 254, which
faces the image side, is a convex spherical surface.
[0222] The sixth lens 260 has negative refractive power and is made
of glass. An object-side surface 262, which faces the object side,
is a concave aspherical surface, and an image-side surface 264,
which faces the image side, is a concave aspherical surface.
Whereby, the incident angle of each view field entering the sixth
lens 260 could be effectively adjusted to improve aberration.
[0223] The seventh lens 270 has negative refractive power and is
made of glass. An object-side surface 272, which faces the object
side, is a convex surface, and an image-side surface 274, which
faces the image side, is a convex surface. It may help to shorten
the back focal length to keep small in size, and may reduce an
incident angle of the light of an off-axis field of view and
correct the aberration of the off-axis field of view.
[0224] The infrared rays filter 280 is made of glass and is
disposed between the seventh lens 270 and the image plane 290. The
infrared rays filter 280 gives no contribution to the focal length
of the optical image capturing system 20.
[0225] The parameters of the lenses of the second optical
embodiment are listed in Table 3 and Table 4.

Third Optical Embodiment
[0230] As shown in FIG. 4A and FIG. 4B, an optical image capturing
system 30 of the third optical embodiment of the present invention
includes, along an optical axis from an object side to an image
side, a first lens 310, a second lens 320, a third lens 330, an
aperture 300, a fourth lens 340, a fifth lens 350, a sixth lens
360, a seventh lens 370, an infrared rays filter 380, an image
plane 390, and an image sensor 392.
[0231] The first lens 310 has negative refractive power and is made
of glass. An object-side surface 312 thereof, which faces the
object side, is a convex spherical surface, and an image-side
surface 314 thereof, which faces the image side, is a concave
spherical surface.
[0232] The second lens 320 has negative refractive power and is
made of glass. An object-side surface 322 thereof, which faces the
object side, is a concave spherical surface, and an image-side
surface 324 thereof, which faces the image side, is a convex
spherical surface.
[0233] The third lens 330 has positive refractive power and is made
of plastic. An object-side surface 332 thereof, which faces the
object side, is a convex aspheric surface, and an image-side
surface 334 thereof, which faces the image side, is a convex
aspheric surface. The image-side surface 334 has an inflection
point.
[0234] The fourth lens 340 has negative refractive power and is
made of plastic. An object-side surface 342, which faces the object
side, is a concave aspheric surface, and an image-side surface 344,
which faces the image side, is a concave aspheric surface. The
image-side surface 344 has an inflection point.
[0235] The fifth lens 350 has positive refractive power and is made
of plastic. An object-side surface 352, which faces the object
side, is a convex aspheric surface, and an image-side surface 354,
which faces the image side, is a convex aspheric surface.
[0236] The sixth lens 360 has negative refractive power and is made
of plastic. An object-side surface 362, which faces the object
side, is a convex aspheric surface, and an image-side surface 364,
which faces the image side, is a concave aspheric surface. The
object-side surface 362 has an inflection point, and the image-side
surface 364 has an inflection point. It may help to shorten the
back focal length to keep small in size. Whereby, the incident
angle of each view field entering the sixth lens 360 could be
effectively adjusted to improve aberration.
[0237] The infrared rays filter 380 is made of glass and is
disposed between the sixth lens 360 and the image plane 390. The
infrared rays filter 390 gives no contribution to the focal length
of the optical image capturing system 30.
[0238] The parameters of the lenses of the third optical embodiment
30 are listed in Table 5 and Table 6.

Fourth Optical Embodiment
[0243] As shown in FIG. 5A and FIG. 5B, an optical image capturing
system 40 of the fourth optical embodiment of the present invention
includes, along an optical axis from an object side to an image
side, a first lens 410, a second lens 420, a third lens 430, an
aperture 400, a fourth lens 440, a fifth lens 450, an infrared rays
filter 480, an image plane 490, and an image sensor 492.
[0244] The first lens 410 has negative refractive power and is made
of glass. An object-side surface 412 thereof, which faces the
object side, is a convex spherical surface, and an image-side
surface 414 thereof, which faces the image side, is a concave
spherical surface.
[0245] The second lens 420 has negative refractive power and is
made of plastic. An object-side surface 422 thereof, which faces
the object side, is a concave aspheric surface, and an image-side
surface 424 thereof, which faces the image side, is a concave
aspheric surface. The object-side surface 422 has an inflection
point.
[0246] The third lens 430 has positive refractive power and is made
of plastic. An object-side surface 432 thereof, which faces the
object side, is a convex aspheric surface, and an image-side
surface 434 thereof, which faces the image side, is a convex
aspheric surface. The object-side surface 432 has an inflection
point.
[0247] The fourth lens 440 has positive refractive power and is
made of plastic. An object-side surface 442, which faces the object
side, is a convex aspheric surface, and an image-side surface 444,
which faces the image side, is a convex aspheric surface. The
object-side surface 442 has an inflection point.
[0248] The fifth lens 450 has negative refractive power and is made
of plastic. An object-side surface 452, which faces the object
side, is a concave aspheric surface, and an image-side surface 454,
which faces the image side, is a concave aspheric surface. The
object-side surface 452 has two inflection points. It may help to
shorten the back focal length to keep small in size.
[0249] The infrared rays filter 480 is made of glass and is
disposed between the fifth lens 450 and the image plane 490. The
infrared rays filter 480 gives no contribution to the focal length
of the optical image capturing system 40.

Sixth Optical Embodiment
[0266] As shown in FIG. 7A and FIG. 7B, an optical image capturing
system 60 of the sixth optical embodiment of the present invention
includes, along an optical axis from an object side to an image
side, a first lens 610, an aperture 600, a second lens 620, a third
lens 630, an infrared rays filter 670, an image plane 680, and an
image sensor 690.
[0267] The first lens 610 has positive refractive power and is made
of plastic. An object-side surface 612, which faces the object
side, is a convex aspheric surface, and an image-side surface 614,
which faces the image side, is a concave aspheric surface.
[0268] The second lens 620 has negative refractive power and is
made of plastic. An object-side surface 622 thereof, which faces
the object side, is a concave aspheric surface, and an image-side
surface 624 thereof, which faces the image side, is a convex
aspheric surface. The image-side surface 624 has an inflection
point.
[0269] The third lens 630 has positive refractive power and is made
of plastic. An object-side surface 632, which faces the object
side, is a convex aspheric surface, and an image-side surface 634,
which faces the image side, is a concave aspheric surface. The
object-side surface 632 has two inflection points, and the
image-side surface 634 has an inflection point.
[0270] The infrared rays filter 670 is made of glass and is
disposed between the third lens 630 and the image plane 680. The
infrared rays filter 670 gives no contribution to the focal length
of the optical image capturing system 60.
[0271] The parameters of the lenses of the sixth optical embodiment
are listed in Table 11 and Table 12.
