Abstract: Addressing the issues of low model completeness and unstable data accuracy in traditional modeling of existing buildings in historical and cultural districts,a technical system of “comprehensive acquisition-data fusion-intelligent reconstruction” is proposed.By utilizing 3D laser scanning and multi-view photogrammetry technologies,millimeter-level geometric frameworks and high-resolution texture information of buildings are obtained respectively.An improved SICP algorithm is employed to achieve precise fusion of multi-source point clouds.Finally,using BIM reverse modeling to construct a realistic 3D model containing building information.The results indicate that this method achieves millimeter-level geometric accuracy and over 98%completeness of the model,supporting multi-dimensional spatio-temporal information overlay analysis.It provides a full lifecycle solution for preventive conservation,virtual restoration,and revitalization of the district.

Key words: BIM reverse modeling, 3D laser scanning, historical and cultural district, point cloud fusion
