Abstract
The detailed and accurate outdoor object tracking is an important task for surveillance system. In this thesis, we proposed a tracking system to track human or vehicle by two PTZ cameras. For the vehicle tracking purpose, we find the relationship between the cameras and studied the trajectory equation of certain point in the image plane during the panning or tilting procedure of the PTZ camera. We can use the moving trajectory to get the required pan/tilt value for displaying the target in the center of the image plane. In the other hand, an effective template matching method is proposed for human tracking. By considering the information of the moving speed and moving direction of the target, we can track the target instantly even long occlusion situation occurred.
