Research Status and Development Trend of Virtual Restoration of Cultural Relics in China—Based on the Visualization and Analysis of Literature Knowledge Mapping in the Past Twenty Years

In order to deeply understand the development status quo and future trends in the field of virtual restoration of cultural relics in China, and to promote the application of virtual restoration technology in the field of cultural relics protection, this paper, with the help of CiteSpace visualization and analysis tools, takes the Chinese literature database of China National Knowledge Infrastructure (CKNI) as the source of data, and conducts a knowledge mapping analysis of the relevant literature on virtual restoration of Chinese cultural relics in the last twenty years. The results show that from 2002 to 2024, the research on virtual restoration of cultural relics in China can be roughly divided into the preliminary exploration stage, the rapid development stage and the integration and innovation stage; high-frequency keywords such as "mural restoration" and "deep learning" represent the research hotspots of virtual restoration of cultural relics, and the application of artificial intelligence technology is the main application of virtual restoration of cultural relics. Research hotspots, the application of artificial intelligence technology is the hot topic of future research in the field of virtual restoration.
