Abstract
New computational methods provide means to deduce semantic information from measurements, such as range scans and photographs of building interiors. In this paper, we showcase a method that allows to estimate elements that are not directly observable – ducts and power lines in walls. For this, we combine explicit information, which is deduced by algorithms from measured data, with implicit information that is publicly available: technical standards that restrict the placement of electrical power lines. We present a complete pipeline from measurements to a hypothesis of these power lines within walls. The approach is structured into the following steps: First, a coarse geometry is extracted from input measurements; i.e., the unstructured point cloud which was acquired by laser scanning is transformed into a simplistic building model. Then, visible endpoints of electrical appliances (e.g. sockets, switches) are detected from photos using machine learning techniques and a pre-trained classifier. Afterwards, positions of installation zones in walls are generated. Finally, a hypothesis of non-visible cable ducts is generated, under the assumption that (i) the real configuration obeys the rules of legal requirements and standards and (ii) the configuration connects all endpoints using a minimal amount of resources, i.e. cable length.
