| 摘 要： | LiDAR技术可以快速获取地形表面高精度3维信息。基于LiDAR数据提取建筑物目标是这一技术的重要应用之一。探讨了一种基于LiDAR点云数据生成不同比例尺的DSM深度影像,然后利用边缘检测算子提取建筑物边缘的方法。实验证明,该方法不需要其他辅助数据,可以从LiDAR点云数据中提取建筑物边缘,并滤除了许多干扰信息。这种方法为基于LiDAR数据提取建筑物目标提供了新的思路。

| Abstract: | LiDAR can capture 3D geographical information quickly.One of important applications is building extraction from LiDAR data.In this article,the LiDAR point cloud data was translated into different scale DSM depth-image.The edge detection algorithm was applied for edge extraction of buildings. The result of the experiment showed that this scheme could extract edge of buildings without accessorial data,and could clear much interferential information,which gave a new way to extract building with the LiDAR data. |
