Extraction of Dense Urban Buildings From Photogrammetric and LiDAR Point Clouds

Extraction of Dense Urban Buildings From Photogrammetric and LiDAR Point Clouds

Point clouds derived from LiDAR (Light Detection and Ranging) and photogrammetry systems are used to extract building footprints in dense urban areas. Two extraction methods based on DSM (Digital Surface Model) images and point clouds are comprehensively evaluated and compared. Firstly, photogrammet...
