IR system for kinematic analysis
First Claim
1. A computer-implemented method for analyzing a golfer'"'"'s body movement, comprising:
- selectively positioning a plurality of markers on a golfer;
using a processor, selectively connectable to a memory and an image acquisition system to acquire a first set of one or more images of the golfer, wherein the images are acquired when the golfer is substantially motionless;
removing some of the plurality of markers from the golfer;
using the processor to acquire a second set of one or more images of a golfer after the removal of some of the plurality of markers, wherein the golfer is in motion at least part of the time during the second set of image acquisition; and
using the processor to compare the movement of two or more body parts of the golfer using the second set of one or more images.

Abstract
A infrared method and apparatus for the kinematic analysis of a golfer is disclosed. The method includes selectively positioning a plurality of infrared markers on a golfer, and optionally on a golf club. Images of the golfer may be acquired before, during, and after he/she swings the golf club. The images may be analyzed to determine the kinematic characteristics of the movement of the golfer'"'"'s body parts. A kinematic analysis of the golfer'"'"'s body parts may then be correlated with a kinematic analysis of the golf club. The method and apparatus disclosed herein provide the advantage of allowing a golfer'"'"'s movement to be correlated with a kinematic analysis of their golf swing while minimizing the physical restrictions on the golfer'"'"'s movement.

8. A computer-implemented method for performing a kinematic analysis of a golfer'"'"'s body, comprising:
-
selectively positioning a first plurality of infrared markers on a golfer; using a processor, operatively connected to a memory, to execute computer program instructions to perform the following steps; acquire images of the golfer, wherein at least some of the images are acquired when the golfer is substantially motionless and at least some of the images are acquired when the golfer is in motion; analyze the kinematics of one or more body parts of the golfer using the acquired images; and correlate the kinematics of the golfer'"'"'s one or more body parts with the kinematics of at least one of a golf club and a golf ball; wherein the first plurality of infrared markers are positioned on the golfer when they are substantially motionless and a second plurality of infrared markers are positioned on the golfer when they are in motion, wherein the first plurality of infrared markers is greater than the second plurality of infrared markers. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer-implemented method for performing a kinematic analysis of a golfer'"'"'s body, comprising:
-
selectively positioning a plurality of markers on a golfer and a golf club; using a processor to perform the following steps; acquire images of the plurality of markers before and after the golfer swings the golf club, wherein the golfer swings the golf club two or more times; and determine the correlation between the movement of the golfer'"'"'s body parts and the golfer'"'"'s club swings based on the acquired images of the plurality of markers; wherein a first plurality of images are acquired while the golfer has a first plurality of markers positioned on the golfer'"'"'s joints and rigid body parts and a second plurality of images are acquired while the golfer has a second plurality of markers positioned only on the golfer'"'"'s rigid body parts. - View Dependent Claims (16, 17, 18, 19, 20, 21)
