Abstract

A system and methods for generating an optimized video stream of a target that is moving within a predefined area uses an automated video system provided with a plurality of video cameras that are positioned about the predefined area by tracking the moving target and determining which of the video cameras is positioned to provide the user defined optimal view of the target and integrating the video stream from that camera to the optimized video stream.

identifying the zone in which the target is as an active zone;

determining a video camera among the plurality of video cameras that has the optimal view of the target defined for the active zone; and

designating the video stream from the selected video camera as the optimized video stream.

2. The method of claim 1, wherein once designated as the optimized video stream, the selected video camera'"'"'s video stream remains as the optimized video stream for a minimum duration.

3. The method of claim 1, wherein the optimal view for each of the zones has a reference angle of interception associated with the optimal view and the step of determining a video camera that has the optimal view of the target for the active zone comprises:

determining for each of the video cameras, the angle of interception between the video camera'"'"'s line of sight and the target'"'"'s orientation axis;

selecting the video camera whose angle of interception is closest to the reference angle of interception associated with the optimal view defined for the active zone.

4. The method of claim 1 further comprising displaying the optimized video stream on to a video display visible to the target.

5. The method of claim 1 further comprising analyzing the video stream from one of the video cameras to detect any abnormalities in the condition of the target or measure performance parameters of the target.

6. The method of claim 1 further comprising transmitting the optimized video stream over a communications network to a remote location.

8. The method of claim 1, wherein at least one particular zone is assigned to a system command and further comprising the step of:

determining whether the target is in the particular zone;

determining how long the target is staying in the particular zone, wherein if the target stays longer than a predefined length of time in the particular zone the automated video system executes the system command assigned to the particular zone.

9. The method of claim 1, wherein the location of the target is provide as a reference Cartesian space coordinate and further comprising the step of transforming the reference Cartesian space coordinate of the target to a coordinate in Cartesian space of each of the video cameras, thus, allowing the video cameras to track and follow the target.

7. The method of claim I further comprising:

storing the optimized video stream and the video streams from each of the plurality of video cameras;

subsequently recalling the recorded optimized video stream and revising the optimized video stream using the stored video streams from the plurality of video cameras.

10. A method for generating an optimized video stream of a target that is moving within a predefined area using an automated video system provided with a plurality of video cameras, each video camera producing a video stream, that are positioned about the predefined area, the method comprising:

defining a desired optimal view for generating the optimized video stream for a performance routine to be performed by the target;

determining the location and orientation of the target as the target is moving through the performance routine;

determining a video camera among the plurality of video cameras that has the optimal view of the target; and

designating the video stream from the video camera having the optimal view as the optimized video stream.

11. The method of claim 10, wherein once designated as the optimized video stream, the selected video camera'"'"'s video stream remains as the optimized video stream for a minimum duration.

12. The method of claim 10, wherein the optimal view has a reference angle of interception associated with the optimal view and the step of selecting a video camera that has the optimal view of the target comprises:

determining for each of the video cameras, the angle of interception between the video camera'"'"'s line of sight and the target'"'"'s orientation axis;
