Based On DSP Target Tracking And Multi-channel Display Technology Research

Whether in military or civilian, target tracking technology has very importantsignificance, which is hot and one of the cutting-edge issues of the countries in the world ofacademic researchers’. This paper mainly studies the hardware and software systems of theinfrared image target tracking technology. The human of stationary background is researchsubject，in this paper. Which research purpose is under the case of non-human intervention, tounderstand and analyze images captured by the camera of the application of imageprocessing, video processing technology and intelligent analysis technology. To completethe task this is detection and tracking of moving targets in the Scenarios. Considered tocomply with project requirements, conduce multi-channel display technology, aimed atexpanding the scope of monitoring, providing more comprehensive monitoring information.Firstly, the paper research on image tracking and multi-channel display hardware circuittechnology, and design the target tracking and multi-channel display based on DSP hardwaresystem. Research and design the hardware platform that the main chip and itsperipheral circuit. In this paper using the DSP chip on TMS320DM642 (Hereinafter referredto as DM642) which is TI Company’s designed for video, image processing and application.Than do the follow job conducted demonstration of the program, the design of the hardwareschematic，layout design and testing work and so on. Introduced the design of eachmodule in the hardware circuit , including image acquisition module, timing controlmodule, image coding output module and so on; Finally, it gets more satisfactory results aftertesting the system.Secondly, the paper study the image preprocessing algorithm, design the appropriate wayto compensate for the noise in the video image acquisition due to the scenarios, light, machineitself. The use of target detection algorithm based on three difference method, which achievesthe moving target detection. Using the cancroids tracking methods complete the target tracking task, compile related software and experiment with better tracking.Finally，This paper aims to make the scene information which captured by multi-channelCCD display on a monitor screen, through researching the image scaling algorithm and themulti-channel display framework to achieve multi-channel video image information at thesame time, real-time display.
