机载LIDAR数据的建筑物三维重建技术

摘要

随着城市化进程的加快,城市规划、环境监测和汽车导航等领域对建筑物有了更多的需求.3D GIS、虚拟现实技术的发展使传统的测量方法逐渐暴露出工作效率和精度方面的不足.LIDAR技术的出现为城市建筑物的快速提取提供了一种新的途径.首先从LIDAR点云数据中自动提取建筑物边缘,然后采用一种新的三维重建方法对提取出来的建筑物进行重建.%With the accelerated urbanization processing, urban planning, environmental monitoring and the areas of automotive navigation,it has more demand on the building. 3D GIS, virtual reality technology to the traditional measurement methods have shown up efficiency and low precision. LIDAR technology provides a new way to extract buildings of cities rapidly. The buildings edge are extracled automatically from LIDAR point cloud data firstly,then a new method is used to reconstruct building model with these extracted building edges.
