Application Research on Digital Archiving of Ancient Architectures Based on Multi-Information Fusion Technique

In view of the problems of traditional paper document recording for ancient architecture protection, such as heavy workload, errors, incomplete information recording and difficult information retrieval, this paper studies the application method of digital archiving of ancient architectures based on multi-information fusion technique, which combined with the advantages of terrestrial 3D laser scanning technology, 3D modeling and virtual reality, by taking the example of Hualin Temple Hall which is a national protected heritage of Song Dynasty in Fuzhou City of China, from the collection and processing of point cloud data to the generation of CAD drawings of surveying and mapping, to the creation of 3D models, and then to the virtual reality design. Finally, aiming at the technical difficulties of poor data compatibility and decentralized management in application, this paper puts forward a specific coping strategy which is “Multi-source Data Fusion and Unified Platform Management”, in order to provide reference for the future repair, protection and research of ancient architectures.
