Fitting system for a golf club
View Patent ↗A method relating to an improved fitting system for a golf club shaft is disclosed herein. More specifically, the present invention utilizes specific data gathered from the golfer's golf swing itself to determine the best performing golf club shaft for this particular golf swing. Even more specifically, the present invention relates to the utilization of infrared motion capturing cameras to record the location data of a golf club shaft throughout a swing. Based on the location data captured, one or more dynamic behavioral characteristics can be calculated to determine one or more preferred shaft characteristics. Using the preferred shaft characteristics, a shaft can be recommended for the golfer having this particular golf swing. The current inventive fitting methodology is preferred to the archaic fitting method of using data gathered from the result orientated ball flight data together with a tedious process of having to try numerous different shafts.
1. A method of fitting a golfer to a recommended shaft comprising:
selectively positioning a plurality of markers on a golf club;
selectively positioning a plurality of cameras, adapted to react to said plurality of markers, around said golfer;
capturing a plurality of location data of said plurality of markers using said plurality of cameras, as said golfer performs a golf swing;
calculating a one or more dynamic behavioral characteristics of said golf club based on said plurality of location data of said plurality of markers throughout said golf swing;
determining a combination of preferred static shaft characteristics based on said one or more dynamic behavioral characteristics; and
selecting said recommended shaft having a combination of static shaft characteristics that most closely resembles said combination of preferred static shaft characteristics;
wherein said combination of preferred static shaft characteristics comprises a shaft length, a shaft weight, a shaft frequency, a shaft torque, a shaft flex, and a shaft EI profile.
2. The method of claim 1 , wherein said plurality of markers requires at least three markers.
3. The method of claim 2 , wherein said step of capturing said plurality of location data further comprises:
identifying a location of each of said plurality of cameras;
identifying an angle between each of said plurality of cameras and each of said plurality markers; and
triangulating the exact location of each of said plurality of markers based on said location of said plurality of cameras and said angle between said plurality of cameras and each of said plurality of markers.
4. The method of claim 2 , wherein said plurality of markers further comprise of an at least one or more clusters of three markers.
5. The method of claim 4 , wherein a position of said one or more clusters of three markers become closer to one another as their placement gets closer to a tip end of said golf club.
6. The method of claim 1 , wherein a number of cameras in front of said golfer is greater than a number of cameras behind said golfer;
wherein said number of cameras in front of said golfer is defined as any camera having a negative y coordinate placement, and said number of cameras behind said golfer is defined as any camera having a positive y coordinate placement for a right handed golfer.
7. The method of claim 1 , wherein said one or more dynamic behavioral characteristics comprises at least one of takeaway max lead, takeaway max lag, takeaway lead duration, takeaway lag duration, takeaway lead/lag recovery point, downswing max lead, downswing max lag, downswing lead duration, downswing lag duration, downswing lead/lag recovery point, takeaway max droop, takeaway max drift, takeaway droop duration, takeaway drift duration, takeaway droop/drift recovery point, downswing max droop, downswing max drift, downswing droop duration, downswing drift duration, downswing droop/drift recovery point, kick velocity, kick acceleration, takeaway max positive torque, takeaway max negative torque, downswing max positive torque, downswing max negative torque.
8. The method of claim 1 , wherein said plurality of location data are presented in a three dimensional Cartesian coordinate system.
