Abstract

An apparatus and method is provided for analyzing a golfer'"'"'s individual swing attributes and determining, based on that analysis, a suitable golf club configuration for that golfer. The swing analysis apparatus include video cameras for obtaining video images of a golfer swinging a golf club, such as a putter, at a golf ball. Images obtained from the video cameras may then be analyzed to determine what golf club dimensions will provide improved results in combination with the golfer'"'"'s individual swing characteristics. The apparatus may additionally include a golf club having predetermined dimensions. When such a golf club is included, images from the video cameras may be analyzed to determine how the golf club of known dimensions must be adjusted to provide the golfer with desirable swing results. The apparatus may also include a method for confirming the dimensions that it is believed will provide a golfer with improve swing results.

Claims

1. A golf analysis system for analyzing a golfer'"'"'s swing, comprising:

a striking location to accommodate a golf ball to be struck with a golf club, wherein the golf club comprises a grip portion and a head, and wherein the golf ball comprises markers;

a first camera directed at said striking location and positioned to capture side view images of the ball;

a second camera operatively coupled to a computer and positioned to capture top view images of the golfer, the club, and the ball during the swing;

a third camera directed at said striking location and positioned to capture front view images of the ball before and after being struck by the club;

a force plate positioned such that the golfer will stand atop the force plate when addressing the golf ball;

a computer operatively coupled to said first, second, and third cameras and said force plate, said computer including;

memory for storing data received from said first, second, and third cameras and said force plate; and

analyzing software for analyzing data supplied to said computer, wherein the data comprises ball movement data from images captured by at least one of the first, second, and third cameras; and

a first display operatively coupled to said computer.

2. The golf analysis system of claim 1, further comprising:

a fourth camera operatively coupled to said computer and positioned to capture side view images of the golfer'"'"'s shoulders during the swing; and

a fifth camera operatively coupled to said computer and positioned to capture front view images of the golfer'"'"'s shoulders during the swing.

3. The golf analysis system of claim 2, further comprising:

a sixth camera operatively coupled to said computer and positioned to capture rear view images of the club head during the swing.

4. The golf analysis system of claim 1, wherein said first, second, and third cameras are high-speed video cameras.

5. The golf analysis system of claim 1, wherein said force plate is configured to dynamically measure the location of the golfer'"'"'s center of weight during the swing and to transfer such measured center of weight data to said computer.

6. The golf analysis system of claim 5, wherein said computer is configured to analyze and transfer said center of weight data to said first display such that the golfer'"'"'s dynamic center of weight is displayed.

7. The golf analysis system of claim 6, wherein said dynamic center of weight is displayed as a trace as a function of time.

8. The golf analysis system of claim 6, wherein said computer is configured to analyze and transfer image data and said center of weight data to said first display such that image data of the golfer, club, and ball during the swing and the golfer'"'"'s dynamic center of weight are displayed simultaneously.

9. The golf analysis system of claim 8, further comprising a second display positioned to be viewable by the golfer at address, operatively coupled to said computer, and configured to display the same information as said first display.

10. The golf analysis system of claim 6, wherein said force plate is further configured to dynamically measure the pressure applied by each of the golfer'"'"'s feet and where such pressure is centered on each of the golfer'"'"'s feet during the swing and to transfer such measured pressure data to said computer.

11. The golf analysis system of claim 10, wherein said computer is configured to analyze and transfer image data, said center of weight data, and said pressure data to said first display such that image data of the golfer, club, and ball during the swing and the golfer'"'"'s dynamic center of weight and dynamic foot pressure are displayed simultaneously.

12. The golf analysis system of claim 1, further comprising a rail positioned on said striking location so as to be intermediate the golfer'"'"'s feet and the golf ball.

13. The golf analysis system of claim 1, wherein said rail includes measurement indicia thereon.

14. The golf analysis system of claim 1, further comprising a laser device positioned in front of the golfer and oriented to project a laser beam at the club head such that said laser beam will be reflected onto a predetermined location when the golf club is properly positioned at address.

17. The golf analysis system of claim 1, wherein the markers comprise bands placed along two perpendicular circumferences of the golf ball.

15. A golf analysis system for analyzing a golfer'"'"'s swing, comprising:

a striking location to accommodate the golfer, a golf club, and a golf ball to be struck with the golf club, wherein the golf club comprises a grip portion and a head, and wherein the golf ball comprises markers;

a first camera directed at said striking location and positioned to capture side view images of the club head;

a second camera directed at said striking location and positioned to capture back view images of the club head;

a third camera directed at said striking location and positioned to capture front view images of the ball before and after being struck by the club;

a force plate positioned such that the golfer will stand atop the force plate when addressing the golf ball;

a rail positioned on said striking location so as to be intermediate the golfer'"'"'s feet and the golf ball;

a computer operatively coupled to said first, second, and third cameras and the force plate, said computer including;

memory for storing data received from said first, second, and third cameras and the force plate; and

analyzing software for analyzing data supplied to said computer, wherein the data comprises ball movement data from images captured by the third camera;

a first display operatively coupled to said computer.

16. The golf analysis system of claim 15, further comprising a laser device positioned behind the golfer and oriented to project a laser beam at the club head such that said laser beam will be reflected onto a predetermined location when the golf club is properly positioned at address.

18. The golf analysis system of claim 15, wherein the markers comprise bands placed along two perpendicular circumferences of the golf ball.
