METHOD FOR PREDICTING A GOLFER'S BALL STRIKING PERFORMANCE
First Claim
1. A method for predicting a golfer'"'"'s ball striking performance, the method comprising:
- determining a plurality of pre-impact swing properties for the golfer using at least one CMOS camera, the CMOS imaging system having a sensor array with at least one megapixel in size, wherein the CMOS imaging system forms a region of interest operating at a frame rate of 1000 to 4000 frames per second prior to the golf club entering the field of view and then forms subsequent regions of interest as the golf club travels through the field of view;
inputting a plurality of golf club properties for a first golf club head of a first golf club, the plurality of golf ball properties for a first golf ball, and the plurality of pre-impact swing properties into a rigid body code;
generating a plurality of ball launch parameters from the rigid body code;
inputting into a trajectory code a plurality of ball launch parameters, a plurality of first atmospheric conditions and a plurality of lift and drag properties for the first golf ball; and
generating a predicted performance from the trajectory code of the first golf ball if struck with the first golf club by the golfer under the plurality of first atmospheric conditions, wherein predicting the performance comprises at least one of predicting the trajectory shape, the trajectory apex, the dispersion of the golf ball, the flight distance of the golf ball and the roll distance of the golf ball.

Abstract
A method for a predicting golfer'"'"'s performance is disclosed herein. The method inputs the pre-impact swing properties of a golfer obtained from a CMOS imaging system, a plurality of mass properties of a first golf club, and a plurality of mass properties of a first golf ball into a rigid body code. Ball launch parameters are generated from the rigid body. The ball launch parameters, a plurality of atmospheric conditions and lift and drag properties of the golf ball are inputted into a trajectory code. This trajectory code is used to predict the performance of a golf ball if struck by the golfer with the golf club under the atmospheric conditions. The method can then predict the performance of the golf ball if struck by the golfer with a different golf club. The method and system of the present invention predict the performance of the golf ball without the golfer actually striking the golf ball.
