对采用两台经纬仪测量空间点的三维坐标时的各种误差因素的影响规律进行了较为深入的理论分析和仿真研究,指出在靠近测量平面的区域内测量误差较大,应尽量避免。同时,可以找到两台经纬仪的最佳距离,从而可大大提高测量准确性。 The influence laws of various error factors in measuring the three-dimensional coordinates of space points by using two theodolites are analyzed in depth. The results show that the measurement error is larger in the area near the measurement plane and should be avoided as much as possible. At the same time, you can find the best distance between two theodolites, which can greatly improve the measurement accuracy.
