Abstract

A system for dynamically tracking and indicating a path of an object comprises an object position system for generating three-dimensional object position data comprising an object trajectory, a software element for receiving the three-dimensional object position data, the software element also for determining whether the three-dimensional object position data indicates that an object has exceeded a boundary, and a graphics system for displaying the object trajectory.

Claims

1. A system for dynamically tracking and indicating a path of an object, comprising:

an object position system for generating three-dimensional object position data comprising an object trajectory;

a software element for receiving the three-dimensional object position data, the software element also for determining whether the three-dimensional object position data indicates that an object has exceeded a boundary; and

a graphics system for displaying the object trajectory.

2. The system of claim 1, in which the software element further comprises a collision detection module for analyzing a plurality of positions on the object trajectory to determine whether the object has exceeded the boundary.

3. The system of claim 1, in which the software element further comprises a tracking confidence analysis module for determining whether to abort displaying the object trajectory.

4. The system of claim 1, in which the display of the object trajectory comprises altering a visual indication of the object trajectory.

5. The system of claim 4, in which the visual indication of the object trajectory is altered before the object has exceeded the boundary.

6. The system of claim 4, in which the visual indication of the object trajectory is altered after the object has exceeded the boundary.

7. A method for dynamically tracking and indicating a path of an object, comprising:

generating three-dimensional object position data comprising an object trajectory;

receiving the three-dimensional object position data and determining whether the three-dimensional object position data indicates that an object has exceeded a boundary; and

displaying the object trajectory.

8. The method of claim 7, further comprising analyzing a plurality of positions on the object trajectory to determine whether the object has exceeded the boundary.

9. The method of claim 7, further comprising determining whether to abort displaying the object trajectory.

10. The method of claim 7, further comprising altering a visual indication of the object trajectory.

11. The method of claim 10, further comprising altering the visual indication of the object trajectory before the object has exceeded the boundary.

12. The method of claim 10, further comprising altering the visual indication of the object trajectory after the object has exceeded the boundary.

13. A system for dynamically tracking and indicating a path of a baseball, comprising:

an object position system for generating three-dimensional object position data comprising a trajectory of a baseball in flight;

a software element for receiving the three-dimensional object position data, the software element also for determining whether the three-dimensional object position data indicates that a baseball has exceeded a boundary; and

a graphics system for displaying the trajectory.

14. The system of claim 13, in which the software element further comprises a collision detection module for analyzing a plurality of positions on the trajectory to determine whether the baseball has exceeded the boundary.

15. The system of claim 13, in which the software element further comprises a tracking confidence analysis module for determining whether to abort displaying the trajectory.

16. The system of claim 15, in which the display of the trajectory comprises altering a visual indication of the trajectory.

17. The system of claim 16, in which the visual indication of the trajectory is altered before the baseball has exceeded the boundary.

18. The system of claim 16, in which the visual indication of the trajectory is altered after the baseball has exceeded the boundary.
