Abstract

This invention relates to the field of historical building conservation and digitization technology, and discloses a collaborative management platform for three-dimensional digital archives of historical buildings. The platform includes: a data acquisition module for acquiring multi-source heterogeneous data of the target historical building; a data processing module for receiving the raw data set, performing format unification and time-base alignment processing on different data sources, and respectively performing point cloud denoising, image feature extraction, and geometric reconstruction processing; a data integration module for establishing a unified spatial coordinate system and generating three-dimensional structural data that uniformly expresses the overall form and detailed features of the historical building; and a data application module for constructing a three-dimensional digital archive database of the historical building based on the fused three-dimensional structural data. This invention achieves closed-loop management of the entire process of historical building management, from raw data acquisition to digital archive construction and application analysis.
