Heritage BIM for Sustainable Development Based on 3D Reconstruction and Semantic Enhancement

In contemporary times, Historic Building Information Modeling (HBIM) has become an effective way for the sustainable development of historic buildings. However, lack of reliable document and technical information remain significant obstacles. Furthermore, discrepancies between the ancient construction regulation and real construction process add difficulty to constructing HBIM. To address these challenges, this research proposes a framework that combines practical 3D reconstruction models with standardized HBIM models to obtain practical HBIM models. For the 3D reconstruction process, laser scanning and photogrammetry are combined together to ensure the quality of the point cloud. While for standardized HBIM models, the parameters that determine the geometric information are identified and presented as variables. The framework is verified by a case study of Twin pagodas in Suzhou, providing ideas for the constructing HBIM and sustainable development of historic buildings.
