A Grid Model for Digital Modeling of Cultural Relics Based on Virtual Reality Technology

An image-based 3D reconstruction method is introduced into the digital protection of material cultural heritage, and an automatic reconstruction method for 3D models of cultural relics is proposed. With the continuous development of the application of 3D digital technology for cultural relics, the realization of high-definition color 3D digital models suitable for cultural relics is an urgent problem to be solved. The digitization of cultural relics faces archaeology. Research, display, education, dissemination, utilization and other application needs, and at the same time facing a series of information acquisition technology means such as digital photography, 2D scanning, 3D scanning, photogrammetry, photometric stereo, CT scanning, geological radar and so on. choose. Focusing on the acquisition of the 3D mesh model of cultural relics and the mapping of 3D textures, several works related to the protection of cultural relics are discussed. The virtual reality technology is used in this paper, which is an important direction of simulation technology, and is an important part of simulation technology and computer graphics. It is a collection of various technologies such as science, human-machine interface technology, multimedia technology, sensor technology, and network technology. It is a challenging cross-technology, frontier discipline and research field.
