With the wide application of computers and Internet systems and the deepening of the idea of cultural heritage conservation, virtual restoration technology has been extensively used in the field of cultural heritage, but there are still many problems. This thesis summarizes the current application cases of virtual restoration in the establishment of digital scenic spots, repair of damaged cultural relics, and color restoration of faded and discolored areas on the basis of the basic concept of virtual restoration technology. In addition, it outlines that the status quo of virtual restoration is characterized by preference for theoretical research, technical failure of meeting the requirements of virtual restoration of cultural heritage, and lack of the combination of various virtual restoration technologies. It also proposes that future research / work should concentrate on establishing a cultural heritage database, improving the software and hardware design of virtual restoration, establishing corresponding principles and standards, and cultivating professional talents so as to provide suggestions for the development of virtual restoration technology in cultural heritage conservation.
