In the past, the museum exhibition mode was limited by the opening hours and the exhibition venue. The stage of its operation has become more and more narrow, and its development space has become more and more limited and there is no room for it. For example, at present, the exhibitions of museums are mostly oriented to the audience in the form of exhibits with explanatory plates and pictures. However, with the development of society and the improvement of people's knowledge level, the audience is no longer satisfied with only enjoying the wonderful exhibits, but more I want to explore the cultural heritage behind the collection, and even eager to remove a certain part of the favorite cultural aspect from the museum and dissolve it into my own life. In order to adapt to the world cultural trend and meet the cultural needs of the society, the application of computer technology is one of the most effective means. Therefore, the digitalization of the museum represents the direction of social development of the world museum.

The museum is an important symbol of the development of a region or even a national civilization. The development trend of the contemporary world museum shows that modern museums are no longer the collection, display and research institutions of simple cultural specimens, but should be a society oriented to the society and serve the public. Educational institutions and information materials consulting agencies. At present, museums in China are often neglected in this respect. To change this phenomenon, it is necessary to involve changes in the museum exhibition mode.

With the development of 3D scanning technology, 3D digital models can play a significant role in the restoration, reproduction, mapping and establishment of digital museums. Compared with traditional archaeological techniques, 3D digital technology has obvious advantages in the following aspects: 3D model can be saved as a copy of real cultural relics, complete, accurate and permanent digital archives for cultural relic protection research; 3D digital technology through digital recording The method provides detection and repair basis for cultural relic protection, and can reconstruct historical relics that are no longer existed or destroyed on the basis of scanning known data. Three-dimensional digital technology can truly record archaeological excavation sites and reproduce the sites before and after archaeological excavation. Original appearance; 3D digital technology can digitally restore cultural relics scattered abroad; virtual museums and virtual exhibitions can provide more free observation points for cultural archaeologists and visitors.
