Research And Design Of Video Tracking System Based On DSP

Target recognition and tracking technology is the focus of the image processing,with a wide range of applications in both military and civilian. In military，such asprecision-guided weapons, missiles, aircraft warning. In civilian，such as trafficmanagement, criminal investigations. In a complex background, extraction, andtracking specific target is an urgent problem.This paper introduces the research status and development trend of domestic andinternational video tracking system, the basic components of the video tracker works.The main work includes:1) The video image tracking system hardware principle, the image sensor usesTMS320C6455image tracking system hardware circuit uses dual DSP design, selecttwo the DSP6455as core processor, complete the core algorithm for target extractionand tracking, selection Xilinx Virtex-XC5VSX95T₂FF1136as a logical unit,complete image acquisition, preprocessing and character overlay function.MT47H64M16BT-3as a memory cache for the image data acquired.2) In the design of hardware circuit to achieve the image acquisition andpre-processing, storage and display character overlay function, given the principle ofthe centroid, center of gravity, the edge and related the classic target trackingalgorithm, and these the DSP implementation of the algorithm and optimization study,stable extracting and tracking on the target is achieved in the design of the hardwaresystem.3) For the current development trend of target identification and tracking, featuretracking template tracking algorithm research, in order to achieve the target trackingin the complex context of target identification and tracking using sift algorithm, thealgorithm in DSP the realization method.Finally, carry experimental verification of the actual target, the results show that,this paper, the design of video image tracking system is stable, strong the objectextraction capacity and anti-jamming ability.
