Digital protection and utilization of Grotto cultural relics

Abstract

With the rapid development of digital technology, the digital protection and utilization of grotto cultural relics have attracted worldwide attention. We introduce the digitalization of grotto cultural relics from three perspectives, namely, the collection, protection, and utilization of grotto cultural relics. Moreover, it laid special stress on analyzing the applying status of the cutting-edge technology related to the digital protection of these cultural relics. In analyzing the cutting-edge research, we found that digital protection research on grotto temple cultural relics has been formed, which is developing rapidly with the dropping cost of technology.The rapid update of cultural relics digitization technology and endless applications extended the scope of cultural relics digitization technology from the initial digital recording to various applications. Thus, listing all the types of technologies involved in cultural relics digitization is impossible. This study discusses the digital protection and utilization of the cultural relics of the cave temple in recent years, mainly involving the visual information category. Moreover, other technical scopes will not be introduced.The protection and utilization of digitization include protection related to digital recording and the utilization of digitized information. The technologies used by them are different but not completely unrelated. This study classifies and summarizes from the technology perspective. The Longmen Grottoes art mainly includes cave niche architecture, stone sculptures, and stele inscriptions. Cave niche architecture refers to the shape of cave niches, eaves, lintels, wood-like buildings on the walls, stone relief towers, and so on. Therefore, the technology used must also be covered extensively. Next, this study mainly introduces 3D information acquisition technology and 3D printing.However, current research topics remain relatively scattered, hence a complete system has not yet been formed. Domestic research also has problems, such as convergence of research perspectives and lack of international exchanges. Finally, through the introduction and analysis of the classic cases of Yungang Grottoes and Longmen Grottoes, the paper explores the future trends and provides relevant technology and application suggestions.The success of the two cases also shows that the digital work of the cave temple is the result of the cross integration of multiple technologies and multiple, and that over emphasis on a certain technology often fails to solve practical problems. How to deeply mine the effective information of the collected data, and flexibly use VR, AR, and artificial intelligence, and other related technologies to use and inherit the cave temple culture is a hot research trend in the future.
