Abstract:
The present invention provides a cost effective, reliable system for producing a virtual scene combining live video enhanced by other imagery, including computer generated imagery. In one embodiment it includes a scene camera with an attached tracking camera, the tracking camera viewing a tracking marker pattern, which has a plurality of tracking markers with identifying indicia. The tracking marker pattern is positioned proximate so that when viewed by the tracking camera, the coordinate position of the scene camera can be determined in real time. The present invention also includes novel filtering algorithms, that vary based on camera motion and maintain accurate positioning.
