摘要
三维激光扫描技术是一门近几年来在不断飞速发展的新兴测量技术,其在地下空间测量中具备一些传统测量技术难以比拟的技术优势。文章中以昆明市2020年地下空间普查项目为例,讨论了基于徕卡RTC360及配套软件的点云数据采集,点云数据处理以及点云质量控制三个关键技术点。同时论证了三维激光扫描技术在地下空间测量中的适用性和优越性。
3D laser scanning technology is a new measurement technology which has been developing rapidly in recent years.It has some technical advantages which are difficult to compare with in the underground space measurement.Taking Kunming underground space census project in 2020 as an example,this paper discusses three technical points:point cloud data acquisition,point cloud data processing and point cloud quality control based on Leica RTC360 and its supporting software.At the same time,the applicability and superiority of 3D laser scanning technology in underground space measurement are demonstrated.
