METHOD AND APPARATUS FOR LOW RESOLUTION GOLF SWING IMAGE CAPTURE
ANALYSIS
Abstract
A method and system for using a low resolution image of a
golfer's swing for analysis is disclosed. Cameras obtain images of
various portions of a golfer's swing. A computer calculates
parameters associated with a golfer and a golf club from the
images. Parameters include body angles, head position, shoulder
positions, arm positions, hand positions, leg positions, foot
positions, club shaft angles, and club head position. Different
portions of the swing are captured using the cameras, including a
static initial address, a backswing, a downswing, a forward swing,
and a follow-through. A computer uses measured parameters from two
or more portions of the swing to determine comparative parameters
during different portions of the swing. The computer uses the
parameters to generate swing analysis outputs, including swing
characteristic information and/or swing profile information. A
correlation table relates identified swing analysis outputs to
recommendations to the golfer to improve the swing.

Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation of U.S. patent
application Ser. No. 15/691,258, filed on 30 Aug. 2017, published
as US 2017/0361193, which is a continuation of U.S. patent
application Ser. No. 13/664,622, filed on 31 Oct. 2012, published
as US 2013/0116808, which claims the benefit of priority from U.S.
Provisional Patent No. 61/555,968, filed 4 Nov. 2011, all of which
are incorporated herein by reference in their entirety for all
purposes.
BACKGROUND
[0002] The present invention relates to a system and method of
analyzing a golfer's swing, and in particular to a system and
method of using a low resolution image capture of a golfer's swing
for analysis.
[0003] The game of golf requires that the golfer exhibit fine
control over the mechanics of his or her swing. Small differences
in a golfer's swing can dramatically affect how the golf ball is
hit and subsequently plays. Both amateur and professional golfers
spend sizeable amounts of time developing the muscle memory and
fine motor skills necessary to improve their game.
[0004] A variety of devices are known in the art that can measure
parameters associated with a golf swing. Such devices can enable a
golfer to measure various aspects of his or her swing, so that the
golfer may critique and improve these aspects. These devices
generally require that a golfer take swings at a ball while being
monitored by launch monitors, video devices and other measuring
devices. The measurements generally taken include the club head
speed, ball speed, launch angle, attack angle, backspin, sidespin
and total distance, among others.
[0005] However, such devices suffer from several deficiencies.
Foremost among these is cost. Some types of launch monitors
generally use radar technology in conjunction with the Doppler
effect to measure the speed and position of the golf club and ball.
These launch monitors must be capable of emitting the precise type
of radar necessary, as well as analyzing the shift in frequency due
to the Doppler effect, in order to provide useful information to
the golfer. The launch monitors therefore tend to be expensive, and
can be especially cost prohibitive for amateur golfers. In
addition, launch monitors can require professional calibration and
set up to be able to obtain accurate information.
[0006] A golfer seeking feedback about his or her swing
characteristics may also employ a golf professional to watch the
golfer's swing and provide feedback about various positions of the
golfer's body before, during, and after hitting the ball. Obtaining
this type of feedback, however, can be expensive. In addition, a
golfer may not have any recorded information available to him or
her from this type of feedback.
[0007] Accordingly, there is a need in the art for a system and
method that would allow amateur and professional golfers alike to
be able to capture and analyze various aspects of their swings in
an accurate and cost effective manner.
SUMMARY
[0008] A method and system for using a low resolution image capture
of a golfer's swing for analysis is disclosed. In one aspect, the
invention provides a method for generating a golf swing analysis
output of a golfer's swing, comprising: obtaining a plurality of
images from at least one camera; calculating at least one parameter
associated with one or more of a golfer and a golf club based on
the obtained images using a computer; and generating a swing
analysis output from the computer identifying at least one swing
characteristic information and/or swing profile information
associated with the golfer's swing.
[0009] In another aspect, the invention provides a system for
generating a golf swing analysis output of a golfer's swing, the
system comprising: at least one camera for obtaining a plurality of
images associated with one or more portions of the golfer's swing;
a computer in communication with the at least one camera, the
computer being configured to calculate at least one parameter
associated with one or more of a golfer and a golf club based on
the obtained images; and at least one swing analysis output
generated by the computer, the swing analysis output identifying at
least one swing characteristic information and/or swing profile
information associated with the golfer's swing.
[0010] In another aspect, the invention provides a method for
generating a golf swing analysis output of a golfer's swing,
comprising: obtaining a plurality of images associated with two or
more portions of the golfer's swing from at least one camera;
calculating a first parameter associated with one or more of a
golfer and a golf club based on the obtained images from a first
portion of the golfer's swing using a computer; calculating a
second parameter associated with one or more of the golfer and the
golf club based on the obtained images from a second portion of the
golfer's swing using the computer; and comparing the first
parameter and the second parameter to generate a swing analysis
output from the computer identifying at least one swing
characteristic information and/or swing profile information
associated with the golfer's swing.

DETAILED DESCRIPTION
[0026] Conventional launch monitors, video devices and other
measuring devices typically used to record characteristics
associated with a golfer's swing focus on obtaining measurements
associated with the movement and parameters of the golf ball as it
is being hit, the initial launch, and during flight. Accordingly,
conventional launch monitors and video devices for recording a
golfer's swing require high resolution images of the golf ball
taken at various times during a golfer's swing, including during
impact of the club head and golf ball and during launch of the golf
ball on an initial flight path, to accurately measure the
parameters associated with the golf ball and, therefore, the
golfer's swing.
[0027] An exemplary embodiment of a process for capturing
information associated with a golfer's swing for analysis is
described herein. In some embodiments, the process includes
obtaining low resolution images of the golfer's swing from one or
more image capture devices, including a high-speed camera.
High-speed cameras capable of taking video and/or still images at a
rapid rate, including at a rate from 200 frames per second to up to
2000 frames per second. However, images acquired at such a rapid
rate may be generally of a lower resolution than may be obtained
using the type of conventional launch monitors and video devices
typically used to record characteristics associated with a golfer's
swing. As a result, an accurate measurement of the various
parameters associated with the movement of the golf ball during and
after the golfer's swing, is not possible within the resolution
limits of the high-speed camera images. Accordingly, the exemplary
embodiment of the process for using a low resolution image capture
of a golfer's swing for analysis described herein instead focuses
on measuring one or more parameters associated with a golfer's body
and/or golf club position during the swing.
[0028] FIG. 1 is a representational view of an exemplary embodiment
of a process 100 for using a low resolution image capture of a
golfer's swing for analysis. In some embodiments, sensor data
associated with a golf swing of a golfer may be obtained from one
or more sources at step 102. In an exemplary embodiment, the sensor
data obtained at step 102 may be obtained from one or more cameras,
including high-speed cameras, as further described below. Next,
process 100 may include a step 104 of calculating swing information
using the sensor data obtained from step 102. In an exemplary
embodiment, step 104 may include calculating one or more parameters
associated with positions of a golfer's body and/or golf club
position during the swing.
[0029] In some embodiments, process 100 may further include using
the calculated swing information from step 104 as inputs to
generate swing analysis outputs at step 106. In an exemplary
embodiment, calculated swing information may be used to analyze the
swing of a golfer and make recommendations regarding training, ball
selection, club selection including putter matching, as well as
other changes to improve the golfer's swing. In addition, in some
embodiments, the generated swing analysis outputs may be used as
part of additional golf-related processes or systems, as further
described below, including, but not limited to: ball fitting
systems, club fitting systems, golfer profile information, training
and/or practice regimens, as well as general feedback to the
golfer.
[0030] Referring now to FIG. 2, a schematic view of an exemplary
embodiment of a system 200 for analyzing a low resolution image
capture of a golfer's swing is illustrated. In some embodiments,
system 200 may be configured to capture information associated with
a golfer during a golf swing. In some embodiments, system 200 may
include one or more components that are configured to capture
and/or record information associated with a golf swing of a golfer.
Different embodiments of system 200 may include different
components. Any of the following components associated with system
200 may be considered optional in some embodiments. Some
embodiments may include a given component, while others may exclude
it. The following description discloses many of the possible
components that may be used with system 200, however, it should be
kept in mind that not every component must be used in a given
embodiment.
[0031] In an exemplary embodiment, system 200 may include one or
more sensors for capturing information associated with a swing of a
golfer. Captured information associated with a swing of a golfer
may include, but is not limited to: visual information, audio
information, weight and/or foot pressure information, as well as
any other type of sensor that may be used to measure parameters
associated with the golfer and/or the golfer's swing. In addition,
captured information may be associated with recorded time stamps or
other mechanisms for assigning time durations or increments to the
captured information.
[0032] In one embodiment, system 200 may include one or more
components associated with a portable movement capture device
configured to capture information associated with a golf swing of a
golfer. One such portable movement capture device that may be used
in accordance with system 200 and the method described herein is
disclosed in commonly owned U.S. Pat. No. 8,982,216, entitled
"Portable Movement Capture Device and Method of Finite Element
Analysis", and filed on Nov. 4, 2011, which application is
incorporated herein by reference in its entirety.
[0033] In some embodiments, system 200 may include one or more
cameras that are configured to capture images and/or video
associated with a golfer's swing. In one embodiment, system 200 may
include a front camera 202 that may be used to capture information
associated with a golfer's swing from a viewing angle facing the
front side of a golfer. In other embodiments, system 200 may
further include a rear camera 204 that may be used to capture
information associated with a golfer's swing from a viewing angle
located behind the golfer.
[0034] In this embodiment, front camera 202 and/or rear camera 204
may be a high-speed camera capable of recording audio and/or visual
information. In some cases, the high-speed camera may record video.
In other cases, the high-speed camera may record multiple still
images taken at a rapid rate. In one embodiment, the high-speed
camera may capture information at a rate from 600 to 1200 frames
per second. In other embodiments, the high-speed camera may capture
information at a higher or lower frame rate. In some cases, the
high-speed camera may capture information at a rate from 200 to 600
frames per second. In other cases, the high-speed camera may
capture information at a rate from 1200 to 2000 frames per second
or greater.
[0035] In still other cases, front camera 202 and/or rear camera
204 may be configured to capture three-dimensional images and/or
video. For example, in some embodiments a 3D camera including
multiple lenses may be configured to capture three-dimensional
images and/or video. In another embodiment, multiple cameras may be
disposed at different locations to capture different views of an
object used to create composite three-dimensional images and/or
video.
[0036] In an exemplary embodiment, the information obtained from
front camera 202 and/or rear camera 204 may be low resolution
images. The term "low resolution image" as used throughout the
specification and the claims refers to an image having a spatial
resolution that does not allow sufficiently accurate measurements
to be made of objects smaller than approximately 2 inches. For
example, low resolution images of a golfer hitting a golf ball
would have a spatial resolution that would not allow accurate
measurements regarding the exact position of the golf ball to be
made from one frame to the next. In other words, images of a low
resolution would show a granular appearance when resolving the
dimensions of a golf ball. In contrast, a high resolution image
would resolve the dimensions of a golf ball smoothly such that it
does not appear granular.
[0037] It should be understood that while the present embodiments
describe a method and system for using a low resolution image
capture of a golfer's swing for analysis, the principles described
herein would apply equally to a method and system using high
resolution images.
[0038] In some embodiments, system 200 may include additional
components configured to obtain information associated with a
golfer during a golf swing. In an exemplary embodiment, system 200
may include pressure sensors 206. In one embodiment, pressure
sensors 206 may be disposed under one or both feet of a golfer
during the golf swing. In another embodiment, pressure sensors 206
may be disposed within one or more shoes of the golfer. With this
arrangement, pressure sensors 206 may be configured to measure the
weight transfer between each foot of the golfer at various points
in the golfer's swing.
[0039] In some embodiments, system 200 may include a component that
is configured to detect the beginning of a golfer's swing in order
to send a signal to one or more of the components to begin
capturing data, including front camera 202, rear camera 204, and/or
pressure sensors 206. In an exemplary embodiment, system 200 may
include one or more trigger sensors 208 that are configured to
detect the beginning of a golfer's swing. In one embodiment,
trigger sensors 208 may include an optical sensor, including, but
not limited to a CCD device, that may be used to generate a trigger
signal. The optical sensor may be configured to detect motions of a
golfer associated with the beginning of a golf swing and generate a
trigger signal to allow system 200 to begin capturing information.
For example, in some cases, the optical sensor may be configured to
detect a pause in movement of a golfer's hands and/or club shaft
associated with the golfer assuming a ready position to begin the
golf swing. In other embodiments, trigger sensors 208 may include a
button pressed by the golfer or another user to indicate to system
200 to begin capturing information.
[0040] System 200 may also include a computer 210. In various
embodiments, computer 210 may include, but is not limited to: a
desktop computer, portable computer, tablet computer, smartphone, a
processor disposed in a digital camera, and/or any other device
including a processor. In some embodiments, computer 210 may be any
processing device that is configured to control one or more
components of system 200. In addition, computer 210 may optionally
include a display 218 that is configured to allow a user to view
and/or interact with information. With this arrangement, a user may
use computer 210 to view and/or interact with the information
obtained with system 200, including allowing a user to analyze
captured information associated with the golf swing of a
golfer.
[0041] In some embodiments, computer 210 may be associated with
system 200 so as to transfer the captured information from one or
more components of system 200 to computer 210. In an exemplary
embodiment, captured information from one or more of front camera
202, rear camera 204, and/or pressure sensors 206 may be
transmitted to computer 210. In this embodiment, a connection may
be provided to allow information transfer to and/or from computer
210 and various components of system 200, including front camera
202, rear camera 204, and/or pressure sensors 206. The connection
may be any type of connection used to transfer information between
devices, including, but not limited to USB, Firewire, Ethernet,
WiFi, Bluetooth, TCP/IP, as well as any other known wireless or
wired connection type. In some cases, the connection may be part of
a local area network (LAN). In other cases, computer 210 and
additional components may be distant from each other and the
connection may be part of a wide area network (WAN). In other
embodiments, one or more components of system 200 may be integrated
with computer 210. In still other embodiments, front camera 202
and/or rear camera 204 may include a processor that may perform
some or all of the functions associated with computer 210,
described above.
[0042] In addition, in some embodiments, trigger sensors 208 may
transmit a trigger signal to computer 210 for controlling any of
front camera 202, rear camera 204, and/or pressure sensors 206 to
begin capturing information. In other embodiments, trigger sensors
208 may be connected, wirelessly or via a wire, to one or more of
front camera 202, rear camera 204, and/or pressure sensors 206
directly.
[0043] In some embodiments, system 200 may include one or more
additional components located locally or remote from computer 210
and/or system 200. With this arrangement, computer 210 may be
configured to transmit the captured information associated with a
golfer's swing, including captured image data and/or generated
swing analysis outputs, as further described below, to different
locations. In one embodiment, a remote location 212 may be in
communication with system 200. Remote location 212 may include a
remote server or other computer that may assist computer 210 with
storing data, processing the captured image data, and/or computing
swing analysis outputs, as well as providing additional information
that may be relevant to a golfer.
[0044] In other embodiments, computer 210 may be configured to
transmit information to a storage medium 214. Storage medium 214
may be any known type of storage medium, including known magnetic
or optical storage media, and may further include removable and/or
portable media. For example, in some embodiments, storage medium
214 may include a portable memory card or other storage medium that
may have the golfer's captured information, including captured
image data and/or generated swing analysis outputs, stored upon it.
The portable memory card or other storage medium may be given to
the golfer for later retrieval or use. In other embodiments,
storage medium 214 may include one or more databases located on a
server.
[0045] In still other embodiments, system 200 and/or computer 210
may provide the golfer's captured information, including captured
image data and/or generated swing analysis outputs to additional
systems 216. Additional systems 216 may include any systems that
are configured to use the captured information associated with the
golfer's swing as input information. In an exemplary embodiment,
additional systems 216 may include any of ball fitting systems,
club fitting systems, golfer profile information, and/or training
and/or practice regimens.
[0046] FIG. 3 is an isometric view of an exemplary embodiment of a
system 300 for obtaining low resolution image capture of a golfer's
swing for analysis. In some embodiments, system 300 may be disposed
near a golfer 302 to obtain captured images of golfer 302, golf
club 304, and/or golf ball 306 during a golf swing by golfer 302.
In an exemplary embodiment, system 300 includes a front camera 310.
Front camera 310 may be any type of camera, including a camera
substantially similar to front camera 202, discussed above. In some
embodiments, front camera 310 may be configured to obtain images of
golfer 302, golf club 304, and/or golf ball 306 from a viewing
angle facing towards the front of golfer 302. In one embodiment,
system 300 may further include a rear camera 312. Rear camera 312
may be any type of camera, including a camera substantially similar
to rear camera 204, discussed above. In some embodiments, rear
camera 312 may be configured to obtain images of golfer 302, golf
club 304, and/or golf ball 306 from a viewing angle behind golfer
302.
[0047] In an exemplary embodiment, front camera 310 and/or rear
camera 312 may be high-speed cameras that are configured to obtain
low resolution images of golfer 302, golf club 304, and/or golf
ball 306 during various points of the golf swing. The captured
images may be further processed to obtain information associated
with the golfer's swing, as further described below. In some
embodiments, front camera 310 and/or rear camera 312 may be a
professional camera. In other embodiments, front camera 310 and/or
rear camera 312 may be a consumer camera available to purchase at a
retail store.
[0048] In this embodiment, system 300 includes a computer 314.
Computer 314 may be any kind of computer, including a computer
substantially similar to computer 210, discussed above. In some
embodiments, computer 314 may be configured to control one or more
of front camera 310 and/or rear camera 312 to obtain images. In an
exemplary embodiment, computer 314 may communicate wirelessly with
front camera 310 and/or rear camera 312 over wireless connection
316. In other embodiments, however, computer 314 may communicate
with various components of system 300 via any known wireless or
wired connection, as described above.
[0049] In addition, in this embodiment, system 300 may include
additional components that are not shown to assist system 300 with
capturing information associated with the golf swing of golfer 302.
In an exemplary embodiment, one or more pressure sensors (not
shown), including pressure sensors substantially similar to
pressure sensors 208, discussed above, may be included and
associated with the feet of golfer 302. System 300 may further
include any of the additional components described above in regard
to system 200.
[0050] Referring now to FIGS. 4 through 9, different exemplary
views of captured information associated with a swing of golfer 302
are shown. In some embodiments, captured information associated
with a swing of golfer 302 may be used to calculate one or more
parameters associated with positions of a golfer's body and/or golf
club position during the swing.
[0051] Referring now to FIG. 4, a representational view of an
exemplary embodiment of an image capture of golfer 302 during a
static initial address taken from a front view is illustrated. In
one embodiment, front camera 310, discussed above, may be used to
obtain captured information associated with golfer 302 at the
beginning of a swing during a static initial address. In an
exemplary embodiment, the captured information associated with the
beginning of the swing may be generally static information related
to absolute or relative positions of portions of golfer 302, golf
club 304, and/or golf ball 306 during the initial address or setup
of golfer 302 in preparation of taking a swing.
[0052] In some embodiments, one or more portions of golfer 302 may
be identified in the static captured image taken at the beginning
of the swing for later comparison during different portions of the
swing of golfer 302. Generally, the portions of interest of golfer
302 may be associated with various regions of golfer 302. For
purposes of reference, portions of golfer 302 may be described
using terms that are relative to the direction of travel of a golf
ball to describe both right-handed or left-handed golfers.
Accordingly, as used throughout the specification and claims,
portions of golfer 302 described as being "front" refer to a
direction facing towards the direction of travel of the golf ball
and portions of golfer described as being "back" refers to the
opposite direction away from the direction of travel of the golf
ball.
[0053] In an exemplary embodiment, a head/body region of golfer 302
may be associated with a head 400, a front shoulder 402, a back
shoulder 404, and/or the hips of golfer 302. Additionally, an
arm/club region of golfer 302 may be associated with a front arm
406, a back arm 408, a front hand 410, a back hand 412, and/or golf
club 304. Finally, a lower body/foot region of golfer 302 may be
associated with a front leg 414, a back leg 416, a front foot 418,
and/or a back foot 420. It should be understood that the various
regions described herein are merely exemplary and any portion of
golfer 302 that is of interest may be associated with any region.
In some embodiments, the positions of any one or more portions of
golfer 302 associated with each region may be captured using a
high-speed camera for analysis of the movement of golfer 302 during
a golf swing.
[0054] In some embodiments, the captured information may include
one or more images that may be used to calculate absolute or
relative positions of portions of golfer 302, golf club 304, and/or
golf ball 306 during the initial address or setup of golfer 302 in
preparation of taking a swing. The calculated positions may include
locations measured in terms of Cartesian coordinates, such as
points along an x-axis and/or y-axis, as well as relative positions
measured in terms of distances between two or more objects. In some
cases, the calculated positions and measurements may be measured
relative to a static golf ball position. With this arrangement, the
static golf ball position may be used as an origin point for
calculating or measuring relative distances and/or angles. In other
cases, an external point of reference, for example, a designated
mark on a wall or other object, may be used as an origin point for
calculating or measuring relative distances and/or angles.
[0055] In this embodiment, a first height 422 associated with the
height of golfer 302 from the ground surface to head 400 is
calculated from the captured information. Similarly, a second
height 424 associated with the position of front hand 410 and a
third height 426 associated with the position of back hand 412 may
also be calculated from the captured information.
[0056] In some embodiments, captured information may be used to
calculate parameters associated with absolute foot position and
separation, as well as relative foot position with respect to the
location of golf ball 306. In this embodiment, a first distance 428
associated with the separation of front foot 418 and back foot 420
is calculated. Similarly, a first relative distance 430 between the
position of back foot 420 and golf ball 306 may be calculated, as
well as a second relative distance 432 between the position of
front foot 418 and golf ball 306 may be calculated from the
captured information.
[0057] In addition, in some embodiments, relative positions in
terms of angular displacement may be calculated from the captured
information. In an exemplary embodiment, the relative position of
front shoulder 402 and back shoulder 404 of golfer 302 may be
calculated as a shoulder angle 434. Similarly, the relative
position of ends of golf club 304 between a proximal end associated
with front hand 410 and back hand 412 and a distal end adjacent to
the ground surface may be calculated as a club shaft angle 436. In
other embodiments, additional measurements may be obtained from the
captured static image of golfer 302 obtained before golfer 302 has
started his or her swing.
[0058] Referring now to FIG. 5, a representational view of an
exemplary embodiment of a backswing image capture of golfer 302
taken from a front view is illustrated. In one embodiment, front
camera 310, discussed above, may be used to obtain captured
information associated with golfer 302 during the backswing. In
some embodiments, the captured information may include a trace 500
depicting the path of a club head of golf club 304 as it travels
along various points during the backswing. In an exemplary
embodiment, captured information may include one or more images
taken at different times during the backswing. In some cases, the
number of images taken during the backswing may be determined based
on the frame rate capabilities of front camera 310. In other cases,
a predetermined number of images may be taken during the
backswing.
[0059] In an exemplary embodiment, the captured information
associated with the backswing may be information related to
absolute or relative positions of portions of golfer 302, golf club
304, and/or golf ball 306 during the backswing. In one embodiment,
an end position 502 of the club head of golf club 304 may be
calculated. End position 502 may represent the final position of
the club head during the backswing, just prior to a transition to
the downswing or forward swing of golfer 302. In addition, a fourth
height 504 associated with the height of the club head of golf club
304 during the backswing may be calculated from a measurement of
the distance between end position 502 and the ground surface. In
other embodiments, additional parameters associated with one or
more portions of golfer 302 may be calculated from measurements of
captured information along various points during the backswing
illustrated in FIG. 5.
[0060] Referring now to FIG. 6, a representational view of an
exemplary embodiment of a forward swing image capture of golfer 302
taken from a front view is illustrated. In one embodiment, front
camera 310, discussed above, may be used to obtain captured
information associated with golfer 302 during the downswing and/or
forward swing towards hitting golf ball 306. In some embodiments,
the captured information may include a trace 600 depicting the path
of a club head of golf club 304 as it travels along various points
during the downswing and forward swing. In an exemplary embodiment,
captured information may include one or more images taken at
different times during the downswing and/or forward swing. In some
cases, the number of images taken during the downswing and/or
forward swing may be determined based on the frame rate
capabilities of front camera 310. In other cases, a predetermined
number of images may be taken during the downswing and/or forward
swing.
[0061] In an exemplary embodiment, the captured information
associated with the downswing and/or forward swing may be
information related to absolute or relative positions of portions
of golfer 302, golf club 304, and/or golf ball 306 during the
downswing and/or forward swing. In one embodiment, a start position
602 of the club head of golf club 304 may be calculated. Start
position 602 may represent the beginning position of the club head
during the downswing, just after the transition from the backswing
of golfer 302. In an exemplary embodiment, start position 602 may
be substantially similar to end position 502 of the downswing,
discussed above.
[0062] In some embodiments, additional parameters associated with
one or more portions of golfer 302 may be calculated from
measurements of captured information along various points during
the downswing and/or forward swing illustrated in FIG. 6. In one
embodiment, a shoulder angle 604 associated with the relative
positions of front shoulder 402 and rear shoulder 404 may be
calculated from captured images of golfer 302 during the downswing
and/or forward swing. In some embodiments, a hand angle 606
associated with positions of front hand 410 and rear hand 412
relative to position of head 400 may be determined. In still other
embodiments, an impact club shaft angle 608 associated with the
relative position of ends of golf club 304 between a proximal end
associated with front hand 410 and back hand 412 and a distal end
adjacent to the ground surface may be calculated during the forward
swing prior to impact with golf ball 306.
[0063] In other embodiments, additional relative or absolute
positions of portions of golfer 302, golf club 304, and/or golf
ball 306 may be calculated at various points along the downswing
and/or forward swing of golfer 302.
[0064] Referring now to FIG. 7, a representational view of an
exemplary embodiment of a follow-through image capture of golfer
302 taken from a front view is illustrated. In one embodiment,
front camera 310, discussed above, may be used to obtain captured
information associated with golfer 302 during the follow-through of
the swing after hitting golf ball 306. In some embodiments, the
captured information may include a trace 700 depicting the path of
a club head of golf club 304 as it travels along various points
during the follow-through of the swing. In an exemplary embodiment,
captured information may include one or more images taken at
different times during the follow-through. In some cases, the
number of images taken during the follow-through may vary, as
discussed above with reference to the backswing, downswing, and/or
forward swing.
[0065] In one embodiment, a finish position 702 of the club head of
golf club 304 may be calculated. Finish position 702 may represent
the final position of the club head at the end of the
follow-through of the swing of golfer 302. In addition, a fifth
height 704 associated with the height of the club head of golf club
304 at the end of the follow-through may be calculated from a
measurement of the distance between finish position 702 and the
ground surface.
[0066] In some embodiments, one or more measurements associated
with golf club 304 hitting golf ball 306 may be calculated using
captured image information. In some cases, while the captured
images may be of such a low resolution as to make accurate
calculations of fine measurements associated with hit golf ball 306
difficult, coarse measurements associated with golf ball 306 may be
possible. In an exemplary embodiment, images from follow-through
may be of sufficient resolution to permit calculation of a launch
angle 706 associated with hit golf ball 306. In another embodiment,
a club head speed of golf club 304 and/or an initial velocity of
golf ball 306 after impact may also be calculated using captured
images from follow-through of golfer 302. In another embodiment,
the angle of attack associated with the swing of golfer 302 may be
determined. The angle of attack represents the angle of the path of
club head of golf club 304 as it travels toward, and then makes
contact with, golf ball 306. In other embodiments, additional
parameters associated with one or more portions of golfer 302 may
be calculated from measurements of captured information along
various points during the follow-through illustrated in FIG. 7.
[0067] In some embodiments, composite information comparing the
calculated positions of portions of golfer 302, golf club 304,
and/or golf ball 306 during various portions of the swing
illustrated in FIGS. 4 through 7 may be used to measure swing
characteristics associated with golfer 302. Referring now to FIG.
8, a composite view 800 is illustrated comparing positions of
portions of golfer 302, golf club 304, and/or golf ball 306 along a
backswing, as illustrated in FIG. 5 above, and a downswing and/or
forward swing, as illustrated in FIG. 6 above.
[0068] In this embodiment, trace 500 depicts the path of a club
head of golf club 304 as it travels along various points during the
backswing and trace 600 depicts the path of the club head of golf
club 304 as it travels along various points during the downswing
and forward swing. A transition point 802 represents the transition
between the backswing to the downswing. In some cases, transition
point 802 is substantially similar to end position 502 and/or start
position 602, discussed above.
[0069] In some embodiments, composite view 800 may include
comparative information that may be measured between trace 500 and
trace 600. In an exemplary embodiment, a vertical apex displacement
distance 804 may be calculated from measurements associated with
the highest point associated with the club head of golf club 304
during each of the backswing and the downswing. In one embodiment,
an inflection zone 806 may be associated with an area of composite
view 800 that represents a predetermined area where trace 500
associated with the backswing crosses over trace 600 associated
with the downswing or forward swing of golfer 302 at a crossing
point 808. In an exemplary embodiment, a horizontal apex
displacement distance 810 may be calculated from measurements
associated with the farthest point of the club head of golf club
304 from golfer 302 during each of the backswing and the
downswing.
[0070] In addition, other parameters may be compared relative to
similar measurements taken at various points along the swing of
golfer 302. In some cases, measurements of foot pressure sensors
associated with weight transfer during one or more of the
backswing, downswing and/or forward swing, and follow-through, may
be compared to determine measurements associated with body
pivoting. Similarly, time measurements associated with each portion
of the swing of the swing of golfer 302 may be obtained from time
stamp information or other time-related information included with
the captured information. In some embodiments, time measurements
may be then compared during one or more of the backswing, downswing
and/or forward swing, and follow-through to determine measurements
associated with the timing of the swing.
[0071] In some embodiments, captured information may be obtained
from a camera located behind golfer 302. In some cases,
calculations may be obtained from a camera with a viewing angle
located behind golfer 302 that would not be possible using a camera
with a viewing angle facing golfer 302. Referring now to FIG. 9, a
representational view of an exemplary embodiment of an image
capture of a swing of golfer 302 taken from a rear view is
illustrated. In one embodiment, rear camera 312, discussed above,
may be used to obtain captured information associated with golfer
302 during any portion of the swing. In this embodiment, a forward
swing is illustrated, however, rear camera 312 may be configured to
capture information associated with any portion of the swing,
including any one or more of the backswing, downswing and/or
forward swing, and follow-through as discussed above. In some
cases, the number of images taken using rear camera 312 may vary,
as discussed above with reference to the backswing, downswing,
and/or forward swing and camera 310.
[0072] In some embodiments, the captured information may include
determining a torso position of golfer 302 upon impact of golf club
304 with golf ball 306. In this embodiment, a shoulder line 900
represents a measured angle between rear shoulder 404 of golfer 302
and the club head of golf club 304. Similarly, a waist line 902
represents a measured angle between the waist or hips of golfer 302
and the club head of golf club 304.
[0073] In an exemplary embodiment, the captured information may
further include initial flight path information associated with hit
golf ball 306. In this embodiment, rear camera 312 may obtain
images associated with the immediate trajectory of golf ball 306
after being hit. In some cases, golf ball 306 may follow a
generally straight flight path 904. However, in other cases, golf
ball 306 may immediately take a path to either direction, including
a slice flight path 906 associated with golf ball 306 traveling to
the right and a hook flight path 908 associated with golf ball 306
traveling to the left. In this embodiment, the initial flight path
information may not be available to front camera 310. As a result,
rear camera 312 may provide additional information associated with
a swing of golfer 302 that would not otherwise be available.
[0074] In some embodiments, captured information and/or calculated
and measured parameters associated with the various portions of the
swing of a golfer may be used to generate swing analysis outputs.
Referring now to FIG. 10, a representational view of an exemplary
embodiment of a process 1000 for using low resolution image capture
inputs associated with a golfer's swing to generate swing analysis
outputs is illustrated. In some embodiments, one or more steps of
process 1000 may be performed using a computer or processor,
including one or more of computer 210, computer 314, and/or a
remote computer, described above.
[0075] In some embodiments, process 1000 may include one or more
steps associated with process 100, described above. In an exemplary
embodiment, process 1000 may include additional detailed steps
configured to categorize and group portions of the obtained inputs
from step 102 to assist with generating swing analysis outputs at
step 106.
[0076] In one embodiment, sensor data associated with a golf swing
of a golfer may be obtained from one or more sources at step 102.
In an exemplary embodiment, the sensor data obtained at step 102
may be obtained from one or more cameras, including high-speed
cameras, as described above, including obtaining captured
information from a front camera at step 1002. In some embodiments,
process 1000 may further include obtaining captured information
from a rear camera at step 1004. In other embodiments, process 1000
may optionally include obtaining additional data from other sensors
at step 1006, including pressure sensor information, as described
above.
[0077] In some embodiments, process 1000 may include a step 1010 of
categorizing the sensor data obtained from step 102, step 1002,
step 1004, and/or step 1006. In an exemplary embodiment, the
product of step 1010 may be categorization of sensor data according
to various portions of the swing of the golfer. In some cases,
process 1000 may use time stamped information or other time-related
indications to assist with categorizing the sensor data at step
1010. In an exemplary embodiment, categorization of the sensor data
at step 1010 may include categorizing the sensor data as being
associated with a static portion 1012, a backswing portion 1014, a
forward swing portion 1016, and/or a follow-through portion
1018.
[0078] Using the categorized sensor data from step 1010, process
1000 may further include the step of calculating swing information
inputs at step 104. In this embodiment, the calculated swing
information inputs at step 104 may include any of the measured
and/or calculated parameters and quantities described in reference
to FIGS. 4 through 9 above. In an exemplary embodiment, the
calculated swing information inputs may be further described as
being related to different types of captured information. In this
embodiment, the different types of captured information includes
body angles/head positions 1020, club shaft positions 1022, swing
path information 1024, and/or initial trajectory 1026 of a golf
ball, as described above.
[0079] In an exemplary embodiment, body angles/head positions 1020
may include information associated with body angles, head position,
shoulder positions, arm positions, hand positions, leg positions,
and foot positions, as well as any other portion of golfer 302.
Club shaft positions 1022 may include information associated with
club shaft angles and club head position of golf club 304, as well
as related information, such as hand positions and/or arm positions
of golfer 302. Initial trajectory 1026 may include coarse
measurements associated with the flight path of golf ball 306,
including an initial velocity, launch angle, and initial trajectory
direction.
[0080] In an exemplary embodiment, process 1000 may be configured
to use one or more of the calculated swing information inputs,
including, but not limited to body angles/head positions 1020, club
shaft positions 1022, swing path information 1024, and/or initial
trajectory 1026, to generate swing analysis outputs at step 106. In
different embodiments, swing analysis outputs generated by process
1000 at step 106 may include one or more of swing characteristics
1028, swing profile information 1030, and flight path information
1032.
[0081] In some embodiments, swing analysis outputs generated at
step 106 may be used to provide recommendations and/or feedback to
a golfer regarding the details of his or her swing and steps to
obtain improved results. FIGS. 11A and 11b illustrate a
representational view of an exemplary embodiment of a table 1100
correlating swing analysis outputs associated with a golfer's swing
to specific recommendations to the golfer for improvements or
corrections.
[0082] In some embodiments, table 1100 may be embodied as a program
or algorithm running on a computer or processor, located either
locally or remotely, and configured to use one or more of the swing
analysis outputs generated at step 106 of process 1000, described
above, to provide relevant recommendations and/or feedback to a
golfer regarding his or her swing. In some cases, the captured
information obtained at step 102, described above, may be processed
automatically using the computer or processor to generate the
recommendations and/or feedback in table 1100. In other cases,
table 1100 may be a lookup table or database that correlates one or
more of the swing analysis outputs to a predetermined
recommendation or feedback.
[0083] In this embodiment, table 1100 may be organized relative to
a swing progression 1102 that identifies the relevant portion of
the swing from which the swing analysis output was generated. In
this embodiment, table 1100 may be organized into a first portion
shown in FIG. 11A associated with a swing of a golfer from an
initial address to a backswing and into the transition to the
downswing. Table 1100 may further be organized into a second
portion shown in FIG. 11B associated with a swing of a golfer from
the transition to the downswing into the downswing, through the
forward swing and to impact and follow-through. In other
embodiments, table 1100 may be organized according to different
criteria. In addition, it should be noted that table 1100 is merely
exemplary and may include a larger or smaller number of identified
swing analysis outputs 1104, as well as a larger or small number of
recommendations and/or feedback 1110.
[0084] In an exemplary embodiment, table 1100 includes a first
column associated with one or more discrete swing analysis outputs
1104. Table 1100 may also include a second column indicating the
source 1106 of the captured information that relates to the
relevant swing analysis output 1104. In some cases, source 1106 may
identify one or more of a front camera, rear camera, foot pressure
sensors, or any other sensor sources used to capture information
associated with a swing of a golfer.
[0085] Next, in some embodiments, table 1100 may further include a
third column that correlates a discrete swing analysis output from
column 1104 with an effect 1108 that may result on the golf ball.
In an exemplary embodiment, table 1100 also includes a fourth
column including one or more recommendations and/or feedback 1110
for the golfer to take to counteract the identified effects 1108
for the given swing analysis output 1104. With this arrangement,
the system and method described herein may be configured to provide
a golfer with analysis of his or her swing and correlate the
identified swing analysis outputs to specific recommendations for
improving one or more of swing characteristics, swing profile,
and/or initial flight path/trajectory of the golf ball.
[0086] For example, captured images taken from a front camera may
identify that a golfer cocks his or her wrists at initial take away
of beginning a swing, resulting in a golf ball that has more spin
and a flight path associated with a slice. As a result, table 1100
provides the golfer with a recommendation to use a golf ball
associated with a lower amount of spin and/or to practice to
eliminate the identified issue with the swing.
[0087] In another example, captured images taken from a rear camera
may identify that a golfer has an inside/outside movement of the
club head of the golf club at initial take away of beginning a
swing, resulting in a golf ball that has a flight path associated
with a hook or a slice. As a result, table 1100 provides the golfer
with a recommendation to use a golf ball associated with a lower
amount of spin and/or to practice to eliminate the identified issue
with the swing. In some embodiments, a rear camera may also be used
to obtain captured images that identify that a golfer has an over
the top transition from backswing to downswing, causing more
sidespin and/or backspin than may be desired. In this case, table
1100 provides a recommendation to use a golf ball associated with a
lower amount of spin and/or to practice to eliminate the identified
issue with the swing.
[0088] Similarly, captured images taken from a front camera may
identify that a golfer has too long of a backswing, or has head
and/or body sway during a backswing instead of a rotation of the
torso, both of which table 1100 indicates may be corrected with
increased practice. Captured images taken from a front camera may
also be used to identify and/or calculate an x-factor angle
associated with the angle between the rotation of the shoulders and
hips at the top of the backswing. A smaller x-factor angle may
cause a decrease in power and spin. As a result, table 1100
provides the golfer with a recommendation to use a golf ball
configured to increase distance and/or to increase flexibility to
increase the golfer's ability to rotate the shoulders relative to
the hips.
[0089] In some embodiments, a swing analysis output 1104 may be
associated with multiple input sources 1106. For example, either or
both of a front camera and a rear camera may be used to identify
that a golfer lifts his or her heel during a backswing, resulting
in a loss of distance when hitting the golf ball. As a result,
table 1100 provides the golfer with a recommendation to use a golf
ball configured to increase distance and/or to increase flexibility
to avoid lifting the heel. Similarly, a loss of distance may also
result from casting at the top of the backswing, caused by a
failure to maintain a wrist angle during the downswing detected
using captured images from a front camera. Accordingly, table 1100
provides the golfer with a recommendation to use a golf ball
configured to increase distance and/or to practice maintaining the
wrists during the downswing.
[0090] In another embodiment, other sensor data may be used, either
alone or in combination with the captured images from a front
camera and/or a rear camera, to identify a swing analysis output
1104. For example, referring now to FIG. 11B, in one embodiment,
source 1106 may include a front camera and/or foot pressure sensors
to identify a reverse pivot in a golfer's swing associated with
having weight forward on the backswing and weight backwards on the
downswing, resulting in inconsistent contact with the golf ball
and/or a loss of distance. To correct this issue, table 1100
provides a recommendation to use a golf ball configured to improve
play, such as a 2 piece or 3 piece game improvement ball, and/or to
practice shifting weight correctly during backswing and
downswing.
[0091] In some embodiments, swing analysis output 1104 may use
comparative calculations between one or more portions of a swing of
golfer. For example, a disparity in the ratio between the time
associated with a backswing and the time associated with a
downswing obtained from a front camera may result in a
recommendation in table 1100 that the golfer practice more to
equalize the timing of his or her swing. Similarly, a swing
analysis output 1104 that indicates that the golfer is dropping or
raising his or her head from initial set up of the swing can result
in an effect 1108 that the golf ball has less spin and a higher
launch or more spin and a lower launch. Accordingly, table 1100
provides a recommendation to use a golf ball associated with a
lower trajectory and higher spin or a higher trajectory and lower
spin, respectively, and to practice more to prevent movement of the
head.
[0092] In some embodiments, swing analysis outputs 1104 may include
analysis of captured images associated with a golf club and/or golf
ball, either alone or relative to one or more portions of a body of
the golfer. For example, in one embodiment, a front camera may be
used to capture images used to calculate that the golfer has a high
angular speed transfer from his or her forearms to the golf club,
resulting in more spin on the golf ball when hit. As a result,
table 1100 provides a recommendation to use a golf ball associated
with a lower amount of spin.
[0093] Similarly, a front camera may also be used to capture images
used to identify a launch angle of the golf ball, which table 1100
provides recommendations to change using different golf balls
associated with various dimple patterns and/or ball compression
values to change the launch angle as desired. The front camera may
also be used to capture images used to identify the angle of
attack. Generally, a steeper angle of attack may cause a golf ball
to exhibit a larger amount of spin when hit and a shallower angle
of attack may cause a golf ball to exhibit a smaller amount of
spin. Accordingly, table 1100 provides a recommendation to use a
golf ball associated with lower amount of spin or higher amount of
spin, respectively.
[0094] In another embodiment, a rear camera may also be used to
capture images used to identify parameters associated with an
initial trajectory of a golf ball. For example, a rear camera may
identity that a golf ball travels on a trajectory immediately to
the left or right. As a result, table 1100 provides a
recommendation to vary the choice of golf ball based on the contact
time of the impact to increase or decrease the compression of the
ball as needed to correct the trajectory.
[0095] As noted above, the correlations listed in table 1100 are
merely exemplary and additional correlations generated using swing
analysis outputs according to the principles described herein may
be made to assist a golfer with improving one or more portions of
his or her swing.
[0096] In some embodiments, swing analysis outputs 106 generated
according to process 100 and/or process 1000, described above, may
be used an inputs for additional systems. Referring now to FIG. 12,
a representational view of an exemplary embodiment of a process
1200 for using swing analysis outputs in combination with various
golf-related systems is illustrated.
[0097] In one embodiment, process 1200 may include associating
swing analysis outputs 106 with golfer profile information 1202. In
some cases, a golfer may have golfer profile information 1202
stored in a database or on a removable media to allow a computer to
retrieve the golfer profile information. It is also contemplated
that a removable media device, such as a portable flash memory
device, could be used with a computer to store and/or retrieve a
golfer's inputs and information associated with swing analysis
outputs 106 as golfer profile information 1202. This would enable a
golfer to reevaluate after some time has lapsed to determine how
their game has changed over time. This would also enable
portability of their information in case of travel or
relocation.
[0098] In an exemplary embodiment, swing analysis outputs 106 may
be used as inputs for training and/or practice purposes, as
described above in reference to FIGS. 11A and 11B. With this
arrangement, a golfer may use swing analysis outputs 106 to receive
recommendations and/or feedback to improve elements of his or her
swing.
[0099] In some embodiments, swing analysis outputs generated at
step 106 may be used as inputs to a system that is configured to
assist a golfer select a golf club or golf ball suited to his or
her swing characteristics or swing profile. In one embodiment,
swing analysis outputs 106 may be used as a component in a club
fitting system 1208 and/or a ball fitting system 1206, including
the ball fitting system disclosed in commonly owned U.S. Pat. No.
8,758,169, entitled "Method and System for Golf Ball Fitting
Analysis", and filed on Jul. 7, 2009, the disclosure of which is
hereby incorporated by reference in its entirety. Club fitting
systems are discussed in US 2009/0326688, filed on Jan. 29, 2009,
and entitled "Systems and Methods for Fitting Golfers with Golf
Clubs," the disclosure of which is hereby incorporated by reference
in its entirety. Club fitting may include fitting any golf club to
a golfer, including, but not limited to putter matching, driver
matching, and matching or fitting one or more irons to a
golfer.
[0100] While various embodiments of the invention have been
described, the description is intended to be exemplary, rather than
limiting and it will be apparent to those of ordinary skill in the
art that many more embodiments and implementations are possible
that are within the scope of the invention. Accordingly, the
invention is not to be restricted except in light of the attached
claims and their equivalents. Also, various modifications and
changes may be made within the scope of the attached claims.
