[Abstract]:In recent years, virtual reality (VR) technology has been widely used in military, medical, entertainment and other fields. At the same time, as a high risk and high risk industry, the coal mine production industry of our country has applied VR technology, and has made a great contribution to the safety of the industry. In this paper, a set of virtual mine application software is developed by using VC _ (10) call OpenGL in Windows environment, and a realistic mine production environment is simulated by high-tech computer technology, which can improve the safety production efficiency of coal mine. It is very important to optimize mine equipment. The specific work of this paper is the theoretical study of the 1: 1 VR technology. This paper introduces the development of VR technology, basic concepts, architecture, classification and so on. The key technologies of VR technology used in virtual mine system, including image-based and model-based VR technology, 3D mine modeling technology are studied. This paper introduces several key technologies of 3D modeling, describes the collection, analysis and preprocessing of mine data, and focuses on the establishment of mine model. According to the characteristics of mine model, the theoretical research of scene model. 3) is realized by static modeling, dynamic modeling, material modeling and effect rendering. This paper introduces the basic principle and classification of LOD algorithm. An improved progressive grid LOD algorithm based on edge folding algorithm is optimized and applied to VR technology of virtual mine. The virtual mine system is developed based on VC platform, and the design and development of the system is carried out by using the 3DS Max interface, which is convenient to optimize the detail of 3DS technology, and the collision detection is used. A friendly man-machine interactive virtual mine application system is realized with the functions of text prompt and so on. At the end of the paper, the research content is summarized and the future development direction is prospected.
