摘要: This paper introduces a modularized tool for the processing of LIDAR data based on analysis neighbor relationships between points with goal to extract planes, lines, and in 3D. The tool's functionalities will be exemplified by application reconstructing building roofs. Detecting buildings within digital surface models is one further step enhance results fully- semi-automatic software tools which handle huge point clouds. comprise sorting coordinates improve efficiency, retrieval topology triangulation points, extraction 3D planes "plane growing" determination roof outlines statistical estimation hypothesis testing their parameters.
