仪高差法的原理及误差分析

随着城市建设的发展,越来越多高层建筑及形状新颖建筑的出现,一些建筑特征点无法用直接测量法测量,为了解决这个问题,本文介绍了一种使用仪高差法来确定测点的平面位置和高程,并对理论成果进行误差分析,同时通过与直接测量法进行比较,实践证明这种方法简单易行,精度可靠。

Principle and Error Analysis of Instrument Height Difference Method

With the development of city construction,more and more high-rise buildings and construction of new shape are presenting.Some of the feature points buildings cannot be measured by direct method.In order to solve this problem,this paper presents a method to determine the point plane location and elevation by instrument height difference measuring,and the error analysis of theoretical results is carried.At the same time comparing with the direct measuring method,the result proves that this method is simple,accurate and reliable.
