REALTIME CAMERA TRACKING AND LIVE VIDEO COMPOSITING SYSTEM AND ITS METHOD

摘要

A real-time camera tracking and realistic image synthesis system and a method thereof are provided to synthesize a road guide and peripheral information with a realistic image in real time in a car navigator, and to output the synthesized image, thereby ensuring real-time effect and accuracy. A feature point prediction and selection unit(19) selects only feature points rom which a 3D position is restored, among feature points for an image. A camera movement prediction unit(13) predicts camera movement information by using the selected feature points. A matching unit(21) compares the current location of a camera with a background geometry model of a peripheral space, and matches the compared information. A synthesizer(25) synthesizes the predicted camera movement information with a realistic image of the peripheral information, and outputs the synthesized image.
