CAMERA TRACKING SYSTEM AND METHOD, AND LIVE VIDEO COMPOSITING SYSTEM |
摘要 |
Provided are a camera tracking system and method and a live video compositing system using the same, which track a main camera with a sub-camera attached to the main camera and thus stably calculate the motion of the main camera even in a dynamic case where most of a static background is occluded by a moving foreground object. The camera tracking system and the live video compositing system can connect feature point tracks that are cut by a foreground object which dynamically moves in an image. Accordingly, the camera tracking system and the live video compositing system can perform the more accurate and quick tracking of a camera even in a case where a foreground object occludes background by dynamically moving.
