  • In order to fulfill the requirement to extract miss distance of moving target in real time in optoelectronic tracking system, a Mean-shift image tracking algorithm based on gray histogram is designed. The target model and the candidate model of the algorithm are improved, and the impact of background pixels on target tracking is suppressed. The algorithm is implemented in the Visual C++ 6.0 platform in the upper computer of the system. When the optoelectronic tracking system captures the moving target, the system uses the Mean-shift image tracking algorithm to track the moving target. The miss distance is used as the input signal of the servo control system to drive the tracking device to track the target. Experiment results show that the proposed Mean-shift algorithm is able to track the moving target in real time precisely and effectively so that the angle deviation can be limited within 30 arc sec.
