With the development of 3D scanning technology, the scope of its application has been gradually expanded. This technology also plays an important role in the conservation of cultural relics. As a result, the digitization during conservation and restoration of cultural relics has become an essential part of a modern museum, and the technology is developing rapidly. Recently, researchers in the Capital Museum have carried out a series of digital modeling projects, and a special effort was made to assist the restoration and reproduction of cultural relics. Various problems, such as color misinterpretation and background interruption were encountered during the process, and solutions were proposed. This research is for mutual discussion by researchers working in computer science and conservation of cultural relics.
