摘要
机载激光雷达(light detection and ranging,LiDAR)可快速获取大面积地表点的三维坐标信息,为建筑物的提取和重建带来了便利。通过阅读大量文献并进行总结,本文概括了国内外机载LiDAR数据建筑物轮廓线的提取方法和研究进展,为机载LiDAR数据建筑物轮廓线提取的研究提供了有效的参考。
LiDAR(light detection and ranging)can quickly get 3d ground points coordinate information of large area,it can bring convenience to building extraction and reconstruction.Through reading a large number of documents and summarizing,this paper summarized the methods and research progress of building contour extraction from airborne LiDAR data at home and abroad,which provides an effective reference for the research of building contour extraction from airborne LiDAR data.
