Research on Digital Protection Technology of Based on Virtual Reality

Abstract

VR technology is a simulation of the virtual world. Users receive and respond to various sensory stimuli provided by the virtual environment with the help of special output and input devices, and interact with people and objects in the virtual world in a natural way to create an immersive feeling. Based on the virtual reality technology, the tourism intangible cultural heritage that has disappeared can be reproduced in front of people. Three technologies are specifically used. First, the three-dimensional modeling technology makes the real scene virtual reappearance, and produces a fully real three-dimensional effect. Second, three-dimensional panorama technology, which uses panoramic images to represent three-dimensional virtual environment, makes the picture effect more realistic. Third, human-computer interaction technology. After adding the somatosensory device, you can get an almost real interaction experience.
