Patent ID: 7283647

Claim:
An analysis tool for capturing and analyzing physical motion of a golf putter during a putting stroke, comprising: (a) one or more video image recording devices; (b) a computer processing environment for processing and storing video image data recorded by said video image recording devices; (c) means for a calibration process to determine an exact trajectory a golf ball must roll along to reach a predetermined target zone and to determine measurement correction factors necessary to compensate for measurement errors caused by optical distortion, misalignment, or positional variance of said individual image recording devices; (d) a light reflective element attached to a surface of said golf putter whereby providing a visual target to record using said video recording devices, detect, and measure position and angle of said light reflective element representing said putter, relative to said exact trajectory with respect to time; (e) a computer readable media containing computer algorithms operable in said computer processing environment for processing said video image data as recorded from each single said video recording device containing recorded image representations of said light reflective element whereby determining a plurality of said position and angular measurements of said light reflective element relative to said exact trajectory, representing said golf putter to which said light reflective element is attached; (f) a display device providing means for presenting said position and angular measurements relative to said exact trajectory; (g) means for processing and correcting said position and angular measurements using said calibration correction factors relative to said exact trajectory; whereby providing corrected, position and angular motion measurement information to aid in instruction and improvement of said putting stroke.
