地面三维激光扫描在道路测图中的应用

摘要

The ground 3D laser scanning technology is widely used on improving the efficiency of road measurement. Taking some roads of Xiamen University of Technology as the object ,based on FARO Focus3D three dimensional laser scanner ,the author carried out point cloud data collecting ,projecting picture extracting ,fast drawing of digital line graphic(DLG),to realize 2D information extraction and 3D model construction ,meanwhile ,the author compared the data with traditional total station data , and obtained the integrity and effectiveness of information of laser cloud data.%地面三维激光扫描技术在提升公路测量效率方面有广泛应用。以厦门理工学院部分道路为研究对象，基于FARO Focus3D三维激光扫描仪，对该道路进行点云数据采集、道路正射影像图的提取、道路数字线划地图（DLG）的快速绘制，实现了二维信息的提取和三维模型的构建，同时与传统全站仪数据对比，得出激光点云数据信息的完整性和效益性。
