| Abstract: | Airborne LiDAR point cloud data filtering is not only the key to obtain high-precision Digital Elevation Model,but also one of the difficulties and the focus in the current study of the LiDAR point cloud data post-processing.In this paper,the method is proposed for filtering LiDAR point cloud data based on progressive TIN and the details of filter principle is described.Firstly,LiDAR point cloud data is organized by regular grid and Triangulated Irregular Network(TIN),seed points are selected by regional su... |
