Based On Digital Image Processing Camera Tracking System

Camera Tracking System that is one of the key technologies in the Virtual Studio is studied in the paper. Compared with prevent works, the new Camera Tracking is brought forward in the thesis. It is new way that is referred to the image of ceiling to design the camera tracking system. To cut down the cost of the system, to meet require of real-time and accuracy the image of ceiling is designed.Assistant camera that fasten the main camera shoot ceiling. The shot images are analyzed and the better filter arithmetic of is chosen. To compute a small part of the image can reduce the work time of the system and it is a new way to prove the rate of the system.Comparing with the Sobel operator and the imaging the theory of CCD Array gets the better Edge detectionImage edges are computed by the Edge detection of the CCD array. And the points correspondences can gained by Hough transform. At last it can gain the position parameters of the main camera.
