Abstract:
A method of extracting a depth map from known camera and tracking data. The method includes the steps of positioning a virtual camera at the coordinates of the tracked camera, setting the field of view to that of the tracked camera, positioning and orienting a synthetic tracked object to the coordinates of the tracked object, clearing the depth buffer and rendering the tracked object as a depth map.
