摘要
采用矢量分析的方法从理论上推导出了直角棱镜与自准直光管各种姿态变化情况对方位测量的影响,得出了自准直光管绕光轴的横滚等效于直角棱镜棱线倾斜工况,二者产生的方位测量误差公式一致;并对姿态变化引入的方位测量误差提出了补偿措施。
The influence on measuring the azimuth of a right-angle prism caused by the pose of the prism and auto collimating light pipe is theoretically deduced, with vector analyzing method. The error formula on measuring the azimuth of a pism is the same,which caused by the horizontal rolling of the auto collimating light pipe as well as the dip angle of the right-angle prism axis＇ s. The method to compensate the measuring error caused by the pose change of the prism and the light pipe is present.
