An improved progressive triangular irregular network densification filtering algorithm for airborne LiDAR data
Airborne lidar is a technology for mapping surface spatial information and has been widely used in many areas of geospatial information disciplines. The filtering process of removing non-ground points has always been the focus of research. PTD (Progressive Triangular Irregular Network Densification)...
