With the development of digital technology, museums are facing a great challenge in the preservation and utilization of 3D data of cultural relics. Based on the demands on long-term preservation of 3D data of cultural relics by museums, a solution of 3D digitization of cultural relics is proposed in this paper for the unbalanced cost-efficiency-result, rare data utilization and inconsistent data storage scheme in the process of digitization. To solve the problem of unbalanced cost-efficiency-result, an evaluation model of 3D digitization has been designed by the Palace Museum, namely comprehensive “cost-efficiency-result” evaluation model. By adding a QR code control device for close range photogrammetry of cultural relics the high digitization cost, low digitization efficiency and inconsistent data quality are solved. Based on the specific needs of preservation and utilization, different grades are specified for 3D data of cultural relics, and a three-layer hierarchical structure and storage scheme is designed in this paper, which solves data inconsistence and difficult data sharing. The above methods have been widely used in the digitization project of the Palace Museum, and the related studies and practices also provide reference for the further development of national 3D digitization standards.
