| summary |
New construction within existing buildings requires documentation of the existing buildings, in a form that one is familiar with from new construction or architectural design. Laser scanning is a powerful tool to survey the built reality. It provides a replica of the existing building in the form of a point cloud. The difficulty is to analyse the resulting amounts of data that has been generated and being able to interpret it as a Building Information Model (BIM). This article proposes a new generic approach for pattern recognition of architectural objects. The procedure is introduced through the use of two examples - polygon fitting, which is important for the generation of new building element classes and wall detection. The second part describes how individual components can be automatically connected to consistent networks. BIM systems walls should be aligned, within predefined limits of accuracy, either perpendicular to or in line with each other. |
