摘要
3维激光扫描技术可以快速、高效且准确的获取测量目标的高精度点云数据,为测量数字化的发展提供了必要的条件。本文以地铁隧道为例,详细阐述了3维点云数据获取的方案、数据处理的基本方法,验证了基于3维激光扫描技术进行地铁3维可视化的可行性。
3D laser scanning technology can fast, efficiently and accurately access the high - precision measurement of the target point cloud data, and provides the necessary conditions for the development of digital measuring. This paper gives an example of subway, and elaborates the method of 3D point cloud data acquisition, data processing and modeling, and verifies the feasibility of 3D visual- ization of subway based on 3 D laser.
