利用全站仪进行工程测量的传统作业模式是首先在已知控制点上设站,后视已知控制点设置后视方位角,然后开始测量。本文探讨的是在已知控制点不通视下自由设站进行工程测量,讨论分析了后方交会点的精度问题,并提出了几点实用性的建议。 The traditional mode of operation for total station engineering surveying is to first set up a station at a known control point and rear view the known control point to set the azimuth of rearview and then start the measurement. In this paper, it is discussed that the station should be set up freely under the condition of the known control points to do engineering survey, the accuracy of the rear intersection point is discussed and analyzed, and some practical suggestions are put forward.
