System and method for measuring a golfer's ball striking parameters
First Claim
1. A method for simultaneously measuring the golf club properties and the golf ball properties during a golfer'"'"'s striking of a golf ball, the method comprising:
- swinging a golf club toward a teed golf ball;
activating a detector as the golf club is swung toward the teed golf ball, the detector transmitting an estimated golf club head speed to an imaging system, the imaging system capable of compiling a plurality of exposures to generate a frame;
taking a first plurality of exposures of the golf club head prior to the golf club head impacting the teed golf ball, the first plurality of exposures having a first time interval between exposures;
striking the teed golf ball with the golf club;
taking a second plurality of exposures of the golf ball after the golf ball has been struck by the golf club head, the second plurality of exposures having a second time interval between exposures, the second time interval different than the first time interval;
generating a frame that includes the first plurality of exposures of the golf club head prior to impact with the teed golf ball and the second plurality of exposures of the golf ball after impact with the golf club head;
wherein the method provides measurements of the golf club head and of the launched golf ball.

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).

10. A system 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 teed within the predetermined field of view;
a detector disposed prior the teed golf ball along a path of a golf club swing, the detector capable of estimating the golf club speed;
means for calculating a first time interval between a first plurality of exposures of the golf club and a second time interval between a second plurality of exposures of the launched golf ball based on the estimated golf club speed; and
means for determining the 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. - View Dependent Claims (11, 12, 13, 14, 15)
