Automatic building modeling from terrestrial laser scanning

摘要: We present an automatic approach to create building models from terrestrial laser points. Our method starts by extracting important features (wall, window, roof, door, extrusion) segmented point cloud. Then visible geometries are recovered direct fitting polygons extracted feature segments. For the occluded parts, geometric assumptions made parts and knowledge about buildings. Finally solid can be obtained combining directly fitted for parts. This achieves high automation, level of detail, accuracy.
