摘要

Tomb excavation is essential for cultural heritage preservation and historical research, but conventional recording methods based on hand-drawn sketches and photographs are time-consuming and prolong artifact exposure. This increases the risk of deterioration caused by environmental fluctuations, microbial attack, and oxidation. To address this issue, this study proposes a rapid documentation workflow integrating a laser scanner and a 360° panoramic camera. The workflow includes three modules: (1) scene construction using high-precision LiDAR point clouds for 3D scene and digital surface model (DSM) generation with multi-temporal registration; (2) dynamic object removal for automatic detection and elimination of occluders during excavation; and (3) orthophoto and 3D model generation from registered multi-temporal point clouds and imagery. Applied to the Wuwangdun tomb, the method produced high-resolution orthophotos and detailed 3D models that support accurate off-site annotation and documentation.
