摘要
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。
This paper introduces the method of 3Ddeformation monitoring of the total station.After the first and the second monitoring,the coordinates of the observation points are calculated by using the principle of coordinate transformation,and the displacement of the monitoring points is obtained.A formula for calculating the displacement accuracy of the monitoring points is derived and given by using the law of error propagation.The results show that the method is feasible.
