摘　　要：为验证光轴指向误差对光学姿态测量精度的影响程度,并为后续实况类设备实现姿态测量提供理论依据,以中轴线法为依据,对算法步骤进行拆分,并对光轴指向误差的影响进行溯源,得出指向误差影响姿态处理结果可从两个方面进行分析。同时对模型内交会算法的直接影响和模型外动态基准的间接影响进行推导分析,将仿真计算和实测数据进行结合验证,获取了在典型中长远光学姿态测量中指向误差200″对姿态角误差不超过0.1°的结论,为现有姿态测量可靠性分析以及后续靶场设备能力拓展奠定了理论基础。To verify the influence of optical axis pointing error on optical attitude measurement accuracy and provide a theoretical basis for subsequent real-time equipment to realize attitude measurement,based on the central axis method,the algorithm steps were split,and the influence of optical axis pointing error was traced.It was concluded that the influence of pointing error on attitude processing results could be analyzed from two aspects.At the same time,the direct influence of the intersection algorithm in the model and the indirect influence of the dynamic reference outside the model were deduced and analyzed.Through the combination of simulation calculation and measured data,the conclusion that the pose angle error is no more than 0.1°in typical medium and long-term optical attitude measurement in the pointing error of 200"was obtained.It lays a theoretical foundation for the reliability analysis of the existing attitude measurement and the capability expansion of the subsequent range equipment.
