闭合环搜索方法的探讨

On the Method of Closed Polyline Searching

在导线、水准、GPS测量中 ,经常需要搜索独立闭合环 ,计算闭合差 ,以检查观测数据的质量。比较传统的测量方法是通过手工搜索独立的闭合环 ,然后列误差方程进行电算 ,这种方法的好处是比较直观 ,但在测量点较多的情况下就比较麻烦。本文介绍一种利用矩阵变换进行独立闭合环搜索的方法 ,通过此方法可以将独立闭合环搜索同平差一起交给计算机处理。

In many surveying works,such as traversing,leveling and GPS survey,searching the closed polyline is usually needed to check the quality of observation data.The traditional method is to search the independent closed polyline manually,then set up formula to do computation.When many points are set up,this method is inefficient.Another method based on matrix transformation is introduced in this paper,by which searching the closed polyline can be dealt with adjustment.
