Real-time visible-talent tracking system
First Claim
1. A system comprising:
- a real-time view-frustum (RTVF) culling processor adapted to;
receive tag-associated data for each of one or more wireless tags;
receive camera information for a film segment generated by a camera;
process the received camera information to determine, for the film segment, a view frustum of the camera; and
correlate the tag-associated data with the view frustum for the film segment to generate frustum-culling information identifying one or more of the wireless tags as intra-frustum tags within the view frustum.

Abstract
In one embodiment, a movie set includes a motion-picture camera and a visible-talent tracking system having several elements. Based on the camera'"'"'s characteristics, items in a portion of the movie set called the view frustum will appear in focus in the film. The camera and a camera-tracking system provide camera-location, orientation, and settings information to a culling processor. The culling processor delineates the location and dimensions of the view frustum based on the received camera information. Wireless tags are attached to talent on set. A tag-locating system tracks the real-time respective locations of the wireless tags and provides real-time spatial information regarding the tags to the culling processor, which determines which tags, if any, are considered to be within the view frustum, and provides information associated with the intra-frustum tags to a track recorder for recording along with the corresponding film frames. That information is variously used after editing.

17. A computer-implemented method comprising:
-
receiving tag-associated data for each of one or more wireless tags; receiving camera information for a film segment generated by a camera; processing the received camera information to determine, for the film segment, a view frustum of the camera; and correlating the tag-associated data with the view frustum for the film segment to generate frustum-culling information identifying one or more of the wireless tags as intra-frustum tags within the view frustum. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
