摘要
In this paper, a new 3D object tracking system is suggested by using the disparity motion information extracted from input stereo image sequences. That is, in the proposed method, by using only the disparity information of input stereo image sequences, moving object can be detected and the location coordinates of the target are extracted and then, using these coordinate values the stereo object tracking is accomplished by just controlling the stereo camera that is mounted on a pan/tilt system. And at the same time, this disparity information can be sent to the receiver together with one of the input stereo image for multiview stereoscopic 3D image reconstruction of the target image under tracking. From some experiments with the 5 frames of the stereo image pairs having 256(x)256 pixels, it is shown that the proposed stereo tracking system can adaptively track the target object with a low error ratio of about 3.38 % on average between the detected and actual location coordinates of the target object.
