Abstract

A system for predicting object location includes a video capture system for capturing a plurality of video frames, each of the video frames having a first area, an object isolation element for locating an object in each of the plurality of video frames, the object being located at a first actual position in a first video frame and being located at a second actual position in a second video frame, and a trajectory calculation element configured to analyze the first actual position and the second actual position to determine an object trajectory, the object trajectory comprising past trajectory and predicted future trajectory, wherein the predicted future trajectory is used to determine a second area in a subsequent video frame in which to search for the object, wherein the second area is different in size than the first area.

Claims

1. A system for predicting object location, comprising:

a video capture system for capturing a plurality of video frames, each of the video frames having a first area;

an object isolation element for locating an object in each of the plurality of video frames, the object being located at a first actual position in a first video frame and being located at a second actual position in a second video frame; and

a trajectory calculation element configured to analyze the first actual position and the second actual position to determine an object trajectory, the object trajectory comprising past trajectory and predicted future trajectory, wherein the predicted future trajectory is used to determine a second area in a third video frame in which to search for the object, wherein the second area is different in size than the first area, in which the object is located in the third video frame at a third actual position.

2. The system of claim 1, further comprising a video output comprising position information relating to the object, the position information being shown relative to a performance gauge.

3. The system of claim 2, wherein the position information relating to the object being shown relative to a performance gauge comprises displaying a spline curve representing the object trajectory.

4. The system of claim 2, wherein the position information relating to the object being shown relative to a performance gauge comprises an indicator showing a height of the object relative to the performance gauge.

5. The system of claim 1, wherein the system further comprises a scoring engine configured to compare the third actual position with the second actual position.

6. The system of claim 5, wherein the scoring engine causes a result of the comparison to be displayed.

7. The system of claim 1, wherein the trajectory calculation element predicts a third location of the object in the third video frame.

8. The system of claim 7, wherein the system further comprises an element configured to compare the predicted third location with the actual third location to determine a margin of error between the predicted third location and the actual third location.

9. The system of claim 8, in which the margin of error is used to determine a third area in a subsequent video frame in which to search for the object, wherein the third area is different in size than the first area and the second area.

10. The system of claim 9, wherein the second area is smaller than the first area and the third area is smaller than the second area.

11. A method for predicting object location, comprising:

capturing a plurality of video frames, each of the video frames having a first area;

locating an object in each of the plurality of video frames, the object being located at a first actual position in a first video frame and being located at a second actual position in a second video frame;

analyzing the first actual position and the second actual position to determine an object trajectory, the object trajectory comprising past trajectory and predicted future trajectory, wherein the predicted future trajectory is used to determine a second area in a third video frame in which to search for the object, wherein the second area is different in size than the first area; and

locating the object at a third actual position in the third video frame.

12. The method of claim 11, further comprising providing a video output comprising position information relating to the object, the position information being shown relative to a performance gauge.

13. The method of claim 12, wherein the position information relating to the object being shown relative to a performance gauge comprises displaying a spline curve representing the object trajectory.

14. The method of claim 12, wherein the position information relating to the object being shown relative to a performance gauge comprises showing a height of the object relative to the performance gauge.

15. The method of claim 11, further comprising

comparing the third actual position with the second actual position.

16. The method of claim 15, further comprising displaying a result of the comparison.

17. The method of claim 11, further comprising predicting a third location of the object in the third video frame.

18. The method of claim 17, further comprising

comparing the predicted third location with the actual third location to determine a margin of error between the predicted third location the actual third location.

19. The method of claim 18, further comprising determining a third area in a subsequent video frame in which to locate the object, wherein the third area is different in size than the first area and the second area.

20. The method of claim 19, wherein the second area is smaller than the first area and the third area is smaller than the second area.

21. A method for predicting object location, comprising:

capturing a plurality of video frames, each of the video frames having a first area;

locating an object in each of the plurality of video frames, the object being located at a first actual position in a first video frame and being located at a second actual position in a second video frame;

analyzing the first actual position and the second actual position to determine an object trajectory, the object trajectory comprising past trajectory and predicted future trajectory, wherein the predicted future trajectory is used to determine a predicted third location in a second area in a third video frame in which to search for the object, wherein the second area is different in size than the first area;

locating the object at a third actual position in the third video frame; and

providing a video output comprising position information relating to the object, the position information being shown relative to a performance gauge.

22. The method of claim 21, further comprising

comparing the third actual position with the second actual position to determine a margin of error between the predicted third location and the actual third location.

23. The method of claim 22, further comprising determining a third area in a subsequent video frame in which to search for the object, wherein the third area is different in size than the first area and the second area.

24. The method of claim 23, wherein the second area is smaller than the first area and the third area is smaller than the second area.

25. The method of claim 21, wherein the position information relating to the object being shown relative to a performance gauge comprises displaying a spline curve representing the object trajectory.

26. The method of claim 21, wherein the position information relating to the object being shown relative to a performance gauge comprises showing a height of the object relative to the performance gauge.
