全站仪自由设站法的探讨与分析

Discussion and analysis of the free station method with total station

本文讨论和分析了2~4个已知控制点的全站仪自由设站法,并给出了点位坐标和点位误差的直接计算法,同时绘制了点位误差等值线示意图,通过一个计算实例表明,直接计算得到的结果基本上与严密平差一致,提出一些实用的说明,供参考。

This paper analyses the free station method with total station for two to four known control points.The method of direct computation of point coordinates and error is given.At the same time,the positioning error contour diagram is plotted.Through an example,we find that the results of the direct computation method agree with that of rigorous adjustment.Several illustrations of practical applications are proposed for references.
