摘要
论述了由于测试转台横轴与竖轴不正交,光电测角装置在测试转台上作测试试验,产生测量参数的误差。提出误差推导的一种新方法,利用向量旋转及坐标系变换理论推导出误差公式。通过对光电平台的检测,测得不同正交度情况下的测量参数误差。实验结果是不正交度在β≤5′时,方位角最大误差为-5″;俯仰角最大误差为-13.2″,均符合精度要求。
Discussing measurement parameter error that is caused by the measurement turn-table cross shaft and vertical axis nonorthogonality during opto-electric measurement angular device is tested.Presenting a new method on error.Deducing error equation that used vector rotating and transfer of axes theory,Measuring out measurement parameter error on different orthogonality by testing optical-electrical device.The experimental result is that position angle maximal error is-5″;pitch angle maximal error is -13.2″,when nonorthogonality is β≤5′,Accord with accuracy standard.
