| 摘 要： | 车载激光扫描系统可以精确、快速获取城市建筑物、道路交通设施、隧道等地物的表面信息,非常适用于城市物体三维空间信息的快速精确获取和在此基础上的三维重建.然而点云不是GIS数据,也不是三维模型,要将大量离散的点处理为可使用的三维模型还需要一系列复杂的过程,现阶段针对车载激光点云三维重建的方法还主要依赖于人工交互或半自动化处理,而且没有针对整个城市地物的三维重建方法.针对这一问题,本文仅提供一种基于地物分类的车载激光点云三维重建的方法,数据基础是已分类的彩色点云,重点是充分利用各类地物的特性,对不同地物使用不同的三维建模策略,以首都师范大学自主研制的车载激光扫描系统获取的三亚市点云数据为实验对象,验证了本文提出方法的可行性与实用性.

| Abstract: | Vehicle-borne laser scanning system can obtain the surface information of city buildings,road traffic facilities and tunnels accurately and quickly,it is very suitable for acquiring the 3D space information of urban objects quickly and accurately that 3d reconstruction on the basis of.But point cloud is not the data of GIS or 3D models,so the conversion from huge amounts of discrete points to 3D models can be used also requires a complex process.At present the method of 3D reconstruction based on vehicle-bo... |
