| 摘 要： | 为提高单线阵CCD相机双激光器立靶测量系统的坐标测量精度，为系统设计提供理论和实验依据，对系统测量误差进行了理论分析，在建立系统数学模型的基础上，推导了系统测量误差公式，采用Matlab软件对测量误差进行了仿真，获得了各误差影响因素对着靶坐标测量误差影响的大小和趋势，以及1 m×1 m靶面内的误差分布，并通过模拟实弹实验对误差分析结果进行了实验验证，实验结果表明，x坐标测量误差的标准差σx为4.1 mm，y坐标测量误差的标准差σy为10.2 mm，模拟实弹实验坐标测量误差与理论分析结果一致。

| Abstract: | In order to improve the measuring accuracy of single-linear array CCD camera and dual-laser vertical target system, theoretical and experimental basis is provided for the system design. Theoretical analysis is carried out on the measuring error and the system measuring error formula is derived based on the establishment of system's mathematic model. Measurement error is simulated by Matlab software. The influence of error factors on measurement error of target coordinates is obtained, and error distribution in 1 m×1 m target surface is obtained. Error analysis is carried out by simulating the live ammunition experiment. Experimental results show that standard deviation σx and σy for measuring error of the x-coordinate and y-coorcinate are 4.1 mm and 10.2 mm respectively, and the error of the simulated live ammunition coordinate is consistent with the theoretical analysis. |
