Moving Target Tracking System Based On The Dsp Complex Background

With the development of computer technology, the image processing is applied more and more extensively in almost fields of national economy. Recently, many companies and scholars at home and abroad think highly of tracking the moving objects automatically in multiple scenes. This paper describes a method that extracts the optical flows from sequent images and tracks the moving objects in real time. We set up a DSPs based on the TMS3206701.First, the DSP boards calculate optical flows (the velocity field of an image) based on the gradient method. Next, the region of 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 head is controlled to keep the object in the field of view of the camera. Therefore we achieve a real time tracking system to the moving objects in the multiple scenes. The results of experiments show that the method can track the moving objects in the multiple backgrounds in real time. For example, the walker walks through the avenue where the trees swayed in the wind, and the toy car speeds up across the brushwood.
