3D DOCUMENTATION AND DATA MANAGEMENT IN THE DAZU THOUSAND-HAND BODHISATTVA STATUE IN CHINA

Abstract. Recently different types 3D data of many cultural heritage are collected, however, how to store and manage these data problem. This paper presents a new solution regarding cultural 3D information fine reconstruction and data management based on 3D modeling. These data were stored with the file system and database, which improved the efficiency of data retrieval; on this basis, hyper-fine 3D models of cultural relics were established. Fine 3D information model based on this method can be used for 3D statistics, virtual restoration and change detection, etc. It can provide a scientific basis for the field of conservation and restoration of cultural relics, but can also provide a reference for fine 3D reconstruction to be applied to other cultural relics. Finally, the Dazu Thousand-hand Bodhisattva has been taken as an example, which verified the feasibility and effectiveness of the program.
