介绍了全站仪任意坐标系三维变形监测方法。即初次、后次监测通过全站仪任何位置设站观测各点三维坐标后,利用坐标变换原理,将监测点的后次观测坐标系坐标与初始观测坐标系坐标进行数学变换,从而直接得到各个监测点的位移量,给出了方法的位移计算公式。应用误差传播定律推导和给出了监测点位移精度计算公式。实际应用计算分析结果表明,该方法是可行的。 The method of three-dimensional deformation monitoring of total station arbitrary coordinate system is introduced. That is, the first time, the second time monitoring station through the total station at any location to observe the three-dimensional coordinates of each point, the use of coordinate transformation principle, the monitoring point coordinates of the observed coordinate system and the coordinates of the initial observation coordinate transformation to directly get each The displacements of monitoring points give the displacement calculation formula of the method. The error propagation law is used to deduce and calculate the displacement accuracy of monitoring points. Practical calculation and analysis results show that this method is feasible.
