A Moving Object Tracking System Based On DSPs

With the development of computer technology, the image processing is applied more and more extensively in most fields of national economy. Recently, many companies and scholars at home and abroad think highly of tracking the moving object automatically in multiple scenes. This paper describes a real time moving object tracking system. We set up a DSPs based on the TMS320C6701. First, the DSP board calculates optical flows (the velocity field of an image) based on the gradient method. Next, the region of the moving object on the image is extracted from the optical flows using knowledge about the region of the object, such as Region-Merge arithmetic, Region-Connection arithmetic or Clustering arithmetic. Finally, the camera is controlled to keep the object in its field of view. Therefore we achieve a real time system to track the moving object in the multiple scenes. This system consists of an image capture card, a personal computer, pan/tilt and DSPs board. The result of experiments shows that the method can track the moving object in the multiple backgrounds in real time. For example, the walker walks through the avenue where the trees sway in the wind, and the toy car speeds up across the brushwood.
