System and method for measuring a golfer's ball striking parameters
First Claim
1. A system for simultaneously measuring the golf club properties and the golf ball properties during a golfer'"'"'s striking of a golf ball, the system comprising:
- a first camera and a second camera, each of the first and second cameras focused toward a predetermined field view;
a golf club having at least one light contrasting area thereon;
a golf ball within the predetermined field of view;
a detector disposed prior to the golf ball along a path of a golf club swing, the detector capable of estimating the speed of the golf club swing during the golfer'"'"'s striking of the golf ball;
means for calculating a first time interval between a first plurality of exposures of the golf club based on the estimation of speed of the golf club by the detector, and a second time interval between a second plurality of exposures of the launched golf ball, wherein a high speed golf club swing has a shorter first time interval than a low speed golf club swing; and
means for determining a plurality of golf club swing properties and golf ball launch properties based on an image frame generated by the first and second cameras, the image frame comprising the first plurality of exposures and the second plurality of exposures.

Abstract
A system (20) for capturing and analyzing golf club information and golf ball information during and after a golfer'"'"'s swing is disclosed herein. The golf club information includes golf club head orientation, golf club head velocity, and golf club spin. The golf club head orientation includes dynamic lie, loft and face angle of the golf club head. The golf club head velocity includes path of the golf club head, attack of the golf club head and downrange information. The golf ball information includes golf ball velocity, golf ball launch angle, golf ball side angle, golf ball speed manipulation and golf ball orientation. The golf ball orientation includes the true spin of the golf ball, and the tilt axis of the golf ball which entails the back spin and the side spin of the golf ball. The system includes camera units (26 and 28), a trigger device (30) and a computer (22).
