【摘要】 光电测距导线测量的精度是当前测绘界普遍关心的课题之一。本文利用PC——1500机编制的固定程序,按坐标变量平差法对单一导线进行严密平差,计算时根据不同的测角与测距精度,拟定了六种典型方案,分别计算了待定点位置的误差元素,如纵、横坐标误差,误误差椭圆元素以及方向差和边长误差等等。然后根据计算数据对平差后导线点的点位误差分布,导线边方向误差的特点进行探讨。同时还可按不同方案的计算结果,分析导线测量所能达到的精度,从而为导线的设计或制定相应规范提供参考。更多还原

【Abstract】 In recent years much attention has been focused on the accuracy ofelectro--optical distance traversing in the surveying field.ThiS paper utilizesthe modular program on microcomputers P C--1500 to adjust the single tra-verse rigorously according to the variation of coordinate methods.We makesix typical designs according to the different accuracy of the angular andthe distance measurement and calculation error elements of each unknownpoints which are errors of X and Y coordinates and the elements of errorsellipse as well as errors of the direction or the side longth.Then we ana-lyse and discuss the error distribution of the points and the error propertyof the traverse direction on the basis of the data obtained.Further we dis-cuss what traversing accuracy accompanies the six designs.All this isrecommended reference in optimizing the design and in determining the properstandard.更多还原
