摘要
由于地下空间GPS信号弱,传统测量方法工作量巨大,因此可利用三维激光扫描技术获取地下空间设施的点云数据。本文以某市地下车库为研究对象,研究具体施测方案,探讨如何有效获取和处理地下建筑物的空间数据。
GPS signal is weak in underground space,and traditional measurement methods are difficult to apply,sothree-dimensional laser scanning technology is used to obtain point cloud data of the underground building.In this paper, we find aunderground garage as a research object,this paper studies the specific measurement scheme, and discusses how to acquire and deal with spatial data of underground building effectively.
