Welcome! I'm CHEN, Sou-Han

PhD Candidate at The University of Hong Kong, Department of Real Estate and Construction

My research develops graph frameworks (AOOGM) for interpretable Architectural Opening reconstruction from point clouds, alongside point cloud embeddings for BIM retrieval. This advances Scan-to-BIM automation, enabling robust digital twins for accessibility and sustainability analysis in existing buildings.
