Semi-Global Filtering of Airborne LiDAR Data for Fast Extraction of Digital Terrain Models

Semi-Global Filtering of Airborne LiDAR Data for Fast Extraction of Digital Terrain Models

Automatic extraction of ground points, called filtering, is an essential step in producing Digital Terrain Models from airborne LiDAR data. Scene complexity and computational performance are two major problems that should be addressed in filtering, especially when processing large point cloud data w...
