激光LiDAR数据在三维城市模型中的应用

The Application of Laser LiDAR Data in 3D City

三维城市模型作为数字城市的一个重要组成部分,它的建立可以拓宽城市规划、设计人员的视角,为城市建筑结构调查、绿地位置设计、道路规划、光照分析、噪声传播和污染研究等提供有效信息,对于城市可持续发展研究具有重要意义。结合生产实际,介绍了激光LiDAR数据在三维城市模型方面的应用,探讨了应用过程中遇到的问题及对策。

3D City Model is an important component of the digital city,its establishment can broaden the viewpoint of urban planning and designing engineers,and can provide effective information for the investigation of urban building structure,the design of green land location,the road planning,the lighting analysis,and the research on noise propagation and pollution,etc.Connecting with the production practice,this paper introduces the application of the laser LiDAR data in three-dimensional city model,and probes into some problems existing in and countermeasures for its application.
