Abstract

A method for automatically identifying an object is disclosed. Preferably, the method is used in conjunction with a performance monitor. A set of markers are selectively positioned on the surface of each of a plurality of golf clubs and golf balls. It is desired that each set of markers for a unique pattern on each of the golf clubs and golf balls. Each unique pattern is preferably acquired and stored. A player may choose any of a plurality of golf clubs and golf balls. When within the field of view of the performance monitor, the pattern on the club and ball is automatically matched with the stored patterns, thereby identifying the type of club and ball.

Claims

1. A method for identifying the type of golf club or golf ball, comprising:

storing image reference information for a plurality of golf clubs and golf balls to provide a library of stored patterns, wherein each of the stored patterns is assigned a Eigen value;

acquiring an image of at least one of said balls and clubs during a swing with at least one camera system to provide a received pattern;

assigning an Eigen value to the received pattern;

matching the received pattern with a stored pattern; and

using a computational device and the assigned Eigen values to identify at least one of said club or ball.

2. The method according to claim 1, wherein the step of matching takes about six seconds or less.

3. The method according to claim 1, wherein the step of matching takes about one second or less.

4. The method according to claim 1, wherein said image reference information is based on a plurality of markers, wherein said markers comprise visible ink.

5. The method according to claim 4, wherein said markers comprise ink responsive to ultraviolet light.

6. The method according to claim 4, wherein said visible ink markers comprise limited spectrum markers responsive to one of colored light and fluorescent light.

7. The method according to claim 1, wherein said image reference information is based on inherent features of said balls and clubs.

8. The method of claim 1, wherein the each of the stored patterns has a unique Eigen value.

9. The method of claim 1, wherein the image reference patterns comprise at least one of manufacturer information, club head model, club shaft model, club shaft stiffness, club head loft, club shaft length, club grip model, or ball model.

10. A method for identifying the type of a plurality of golf clubs and golf balls, comprising:

storing image reference patterns based on a plurality of markers for each type of the plurality of golf clubs and golf balls;

assigning each reference pattern an Eigen value;

acquiring an image of at least one of said balls and clubs during a swing using at least one camera system to provide a received pattern; and

identifying with a computational device the type of at least one of said club or ball based on a comparison of the received pattern to said image reference patterns in about six seconds or less using Eigen values.

11. The method according to claim 10, wherein said plurality of markers comprise visible ink.

12. The method according to claim 11, wherein said markers comprise ink responsive to ultraviolet light.

13. The method according to claim 11, wherein said visible ink markers comprise limited spectrum markers responsive to one of colored light and fluorescent light.

14. The method according to claim 10, wherein said image reference patterns are based on inherent features of said balls and clubs.

15. The method of claim 10, wherein the step of acquiring comprises receiving a pattern formed from placement of fluorescent markers on the surface of the golf club or golf ball.

16. The method of claim 10, wherein the type of golf club or golf ball is based on at least one of manufacturer, head model, shaft model shaft stiffness, head loft, shaft length, grip model, and ball model.

17. A system for identifying the type of golf club and golf ball, comprising:

at least one camera system; and

a computational device capable of comparing an acquired image to a library of stored reference patterns with assigned Eigen values and identifying at least one of the type of golf club and golf ball, wherein the type of golf club is determined by comparison of at least one parameter selected from the group consisting from manufacturer, head model, shaft model shaft stiffness, head loft, shaft length, and grip model to the library of stored reference patterns and assigned Eigen values, and wherein the type of golf ball is determined by comparison of the ball model to the library of stored patterns and assigned Eigen values.

18. The system according to claim 17, wherein the library of stored reference patterns comprise club manufacturer, club head model, club shaft model, club shaft stiffness, club head loft, club shaft length, club grip model, and ball model for a plurality of golf clubs and golf balls.

19. The system according to claim 17, wherein the acquired image comprises a pattern based on a plurality of UV markers.

20. The system according to claim 17, wherein the acquired image comprises a pattern based on a plurality of visible markers.

21. The system according to claim 17, wherein said library of stored reference information comprises about 200 or more objects, each assigned a unique Eigen value.
