| The photoelectric real-time imaging tracking system has wide applications in military affairs including monitoring warn, precision guidance, fire control and other civilian-use fields, such as industry manufacture, disease diagnosis and traffic monitoring. With the technology development, the increasing flexibility and hidden ability of the target make the real-time feature and precision to be the key points during the research of tracking system. Therefore, the research of the efficient and high precision imaging tacking system is a matter of great theoretical significance and value for engineering complication.With the analysis of current real-time imaging tracking system and its future trend, this paper has designed and built a real-time imaging tracking system hardware platform which is based on the template matching algorithm. Aiming to improve the real-time ability and precision, the platform is designed to track objects of complex ground situation, and to realize target recognition and precision tracking algorithms. Firstly, the paper makes a deep analysis to several classic target recognition algorithms, according to their merits and faults, the template matching method is chosen as the core algorithm of the imaging tracking system. Secondly, based on the operating feature of the chosen algorithm, the paper has designed and built an information processing system centering on DSP (Digital Signal Processor) and FPGA (Field Programmable Gate Array), which integrates the hardware structure and tracking algorithms, and the MCU (Micro Control Unit)-oriented control system combines the parameter input, information process and optical-cabin control into a complete closed loop controlled photoelectrical imaging tracking system. Finally, according to abundant outfield experimental data, the paper has tested and verified the anti-interference ability, tracking precision, flexibility, stability and real-time ability, and the result shows that specifications of the system are with great advanced characteristic and universality which satisfy missile tactical requirements. |
