摘要
影响光电跟踪系统精度的因素很多,采用一种方法无法准确描述各种因素的影响结果,使得光电跟踪系统控制精度低,控制误差大,为了全面描述准确描述各种因素对光电跟踪系统精度的影响,提出基于信息融合的光电跟踪系统高精度控制方法。首先对光电跟踪系统控制研究现状进行分析,指出当前光电跟踪系统控制方法存在的局限性,然后基于信息融合理论分别采用不同方法对光电跟踪系统精度进行拟合,最后通过具体实例对光电跟踪系统控制精度进行分析,本文方法的光电跟踪系统控制精度均值达到了96%以上,光电跟踪系统控制时间明显小于对比光电跟踪系统控制方法,结果表明,本文方法可以有效改善光电跟踪系统的控制效果,解决当前光电跟踪系统控制过程中存在的一些难题。
There are many factors affecting the accuracy of the photoelectric tracking system. Only one method cannot accurately describe the results of various factors,which makes the control accuracy of the photoelectric tracking system low and the control error large. In order to describe the influence of various factors on the accuracy of the photoelectric tracking system comprehensively and accurately,high precision control method for tracking system based on information fusion is proposed. Firstly,the research status of photoelectric tracking system control is analyzed,and the limitations of current photoelectric tracking system control methods are pointed out. Then,based on information fusion theory,different methods are used to fit the accuracy of photoelectric tracking system. Finally,the control accuracy of photoelectric tracking system is analyzed through specific examples. The average control precision of the photoelectric tracking system is over 96%,and the control time of the photoelectric tracking system is obviously less than that of the control method of the comparative photoelectric tracking system. The results show that the control effect of photoelectric tracking system can be effectively improved by this method,and some difficult problems in control process of current photoelectric tracking system can be solved.
