Method and system for golf swing analysis and training for putters

Abstract

Techniques for measuring and modeling club-like sports instrument inertial motion sensing signals are disclosed. The disclosed method and system generate corrected output of a motion sensing circuit, which circuit includes an inertial measurement unit and associates with a putting club-like sports instrument. One aspect of the disclosed subject matter includes a method and system for isolating analysis positions of a golf swing, which analysis positions facilitate measuring and modeling the swinging motion. Another aspect of the disclosed subject matter includes a method and system for correcting golf swing measurement errors for more accurately measuring and modeling the swinging motion. Yet another aspect of the disclosed subject matter provides a method and system for determining an impact position of a swinging sports instrument.

1 . An intelligent golf putting system for improving of putting performance, comprising: 
 a golf putting club head;    a shaft of a dimension, weight, and tensile properties essentially similar to a standard golf putting club;    a grip handle associated with said shaft of a dimension and weight essentially similar to a standard golf putting club;    electronic components inserted into said grip handle, the electronic components comprising: 
 a plurality of accelerometers capable of producing linear acceleration measurements of the sports device in three (3) axes during a swing of the sport device;  
 a plurality of gyroscopes capable of producing angular rate measurements of the sports device in three (3) axes during the swing of the sport device; and  
 an RF transmitter for transmitting the linear acceleration measurements and the angular rate measurements;  
   a radio frequency link box for receiving the transmissions of the linear acceleration measurements and the angular rate measurements from the radio frequency transmitter;    logic coupled to the radio frequency link box for transforming the linear acceleration measurements and the angular rate measurements into swing information corresponding to the swing of the sport device; and    a display for displaying the swing information.
