Automatic building modeling from terrestrial laser scanning

Chapter
Part of the Lecture Notes in Geoinformation and Cartography book series (LNGC)

Abstract

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