摘　　要：光电跟踪系统的精度效果与多种信息密切相关,当前单一传感器信息无法全面描述目标状态,导致光电跟踪系统的跟踪误差大,难以满足实际应用的要求。为了克服当前光电跟踪系统存在的弊端,提高光电跟踪的精度,设计了基于信息融合的光电跟踪系统精度提高方法。首先采用多个传感器对光电跟踪系统跟踪目标的信息进行采集,然后对不同信息进行融合描述光电跟踪系统的跟踪目标状态,引入滤波器对目标状态进行估计,最后进行了光电跟踪系统的性能测试实验。结果表明,本文方法可以从多个角度描述目标的状态,提高了光电跟踪系统的跟踪精度,同时光电跟踪系统的跟踪误差要明显低于单一信息的光电跟踪系统方法,能够对目标进行有效的跟踪和检测。The precision effect of the photoelectric tracking system is related to a variety of information. Single information cannot describe the state of the target in an all-round way, which leads to the large tracking error of the photoelectric tracking system, and it is difficult to meet the requirements of the practical application. In order to overcome the disadvantages of current photoelectric tracking system and improve the precision of photoelectric tracking, a method of improving the precision of photoelectric tracking system based on information fusion is designed. Firstly, several sensors are used to collect the tracking target information of the photoelectric tracking system, and then different information is fused to describe the tracking state of the optoelectronic tracking system, and the target state is estimated by the filter. Finally, the performance test experiment of the photoelectric tracking system is carried out. The results show that this method can describe the state of the target from many angles and improve the tracking precision of the photoelectric tracking system. At the same time, the tracking error of the photoelectric tracking system is obviously lower than the single information tracking system, which can effectively track and detect the target.
