Abstract

Automatic modeling of As-Is BIM Models will become more and more important. While a lot of progress has been made to automate the scan-to-bim process, there are still many challenges and problems to be solved. A multi faceted tool that helps various stakeholders in the different phases of construction of a building is being developed by Fraunhofer Italia. Part of this tool generates an IFC BIM Object from an already segmented point cloud instance of BIM objects. This paper presents the research on BIM objects and different ways to represent them in the IFC format, only doors are focused in this thesis paper. Results of experimentation on existing methods to extract crucial features from a point cloud, which could help reconstruct sub structures of a door, are presented. Experimentation revealed that oriented bounding boxes generated from appropriate segmented point clusters does approximately resemble a door, as well as provide approximate segmentation of sub structures of a door. A first assessment of the quality of this approach is provided by performing both a quantitative and qualitative analysis. Quantitative analysis is done by comparison with a BIM model generated by an expert and qualitative analysis is done by examining answers to a subjective questionnaire about the results of the experiment.
