基于免棱镜全站仪的竖井高精度测量

摘要

In order to solve the invisibility problem of mounted total station on the ground and the bottom of shaft,it does not use connection triangle measurement to transfer ground coordinates and azimuth to the bottom of the shaft,but carries out free station measurement,to realize the unification of the coordinate and elevation system through the measured reference points and coordinate conversion.The proposed method is simple,secure and precise,which provides a new way to shaft survey.Using the high precision data of shaft measured by the reflectorless total station,three-dimensional (3D) scattered diagram of shaft can be drawn with effectiveness.%为了解决竖井测量中地面设站仪器与井底不通视问题,文中不采用联系三角形测量将地面坐标和方位传递到井底,而进行自由设站测量,并通过联测基准点、坐标高程转换,实现地面、井底坐标与高程系统统一,操作简单快捷、精度高,为竖井测量提供一种新思路.利用免棱镜全站仪测量的竖井高精度数据,绘制竖井三维散点图,达到了良好效果.
