Electro-optical Observer Shafting Perpendicularity Error Analysis and Correction

光电观瞄仪方位轴和俯仰轴的轴系垂直误差会带来对目标测量的误差。采用坐标旋转的分析方法,可得轴系垂直误差对目标测量误差的传递模型。对误差传递模型进行简化获得误差修正公式,此公式能用于修正轴系垂直误差对测量目标指示精度的影响。

The azimuth and elevation shafting perpendicularity error affect the indication precision of electro-optical observer. Using coordinate rotating analysis method, the error model of the affecting of shafting perpendicularity error can be derived. The error correction formula is derived by simplifying the error model, and the formula can correct the target indication error impacted by shafting perpendicularity error.
