Abstract


With the advancement of science and technology and the emergence of the new DSP devices , as the core device to TMS320DM642 image tracking system design . First , according to the functional requirements of the system , the overall system design , and discusses in detail the the submodule image tracking system hardware circuit design method . Secondly , this paper presents a related tracking algorithm based on the frequency domain , the algorithm of image differential scale space filtering establish target template , and large-scale computing the match from the time domain to the frequency domain to solve the traditional correlation tracking algorithm for computing the amount of the big drawback enhanced matching precision and anti-jamming . Double contrast similarity detection methods used in the template update strategy to improve the stability of the target tracking . And on this basis, the software part of the system design . Finally, system debugging and experiments . The experiments show that the algorithm has good real-time , high positioning accuracy and tracking stability .
