摘要
在实际工作中,特殊点的定位测量,在GPS等先进的仪器设备无法解决的情况下,我们会应用到"边角后方交会"的测量方法,按照传统的计算方法,在没有多余观测条件时,如果已知数据或者观测数据出现错误时,尽管计算过程是正确的,但计算结果仍然是不正确的,这时如何发现计算结果的错误就显得非常重要。本文结合实践总结出了一种检查方法,经过验证,能够准确应用"边角后方交会"方法解决生产过程中的一些特殊问题。
In practice,when the GPS and other advanced equipments are not adequate enough to measure a special point＇s position,we will apply to the＂side angle resection＂measurement method.Based on the traditional method,under the conditions of the absence of redundant observations,if the known data or observation data occurs error,even though the calculation is correct,the results are still incorrect.Under such a scenario,how to find the error of the calculation result is very important.Based on the production practice,this paper summarizes a examination method,which has been verified to solve some special problems accurately using＂side angle resection＂measurement method.
