摘要
机载激光雷达(light detection and ranging,LiDAR)是一种主动遥感观测技术,在生成数字地面模型(digital terrain model,DTM)和数字表面模型(digital surface model,DSM)、建筑物建模、城市三维重建等方面有着巨大的潜力。从机载LiDAR点云数据中提取建筑物顶面轮廓的方法并进行相关实验,结果表明该方法能够提取较高精度的建筑物顶面轮廓,这对于城市精细化建模、输电线路三维设计等具有较大意义。
Airborne LiDAR is a new active remote sensing technology,which has great potential in DTM and DSM generation,3D building modeling and 3D city reconstruction.In this paper,the workflow and analyze methods of building roof boundary extraction based on airborne LiDAR were described.Experimental results showed the methodology proposed could extract accurate building roof boundary based on airborne LiDAR,so it could be applied in city reconstruction and 3D designing of transmission lines.
