Virtual reality oral cavity teaching system

Abstract

The invention belongs to the virtual reality technology field, and discloses a virtual reality oral cavity teaching system. The virtual reality oral cavity teaching system comprises a tooth scanning module, a data processing optimization module, a virtual reality interaction module, and a case classification and diagnosis method automatic processing module. The tooth scanning module is used to convert a CCD data model into a 3D model automatically, and a complete tooth database is established. By adopting the data processing optimization module, scanning data is in accordance with a Unity scene. The virtual reality interaction module is used to realize the virtual reality oral cavity teaching system provided with visual sense, auditory sense, and tactile sense in VR hardware equipment. The case classification and diagnosis method automatic processing module is used to automatically prompt various defects caused by separation of different tooth positions by using pictures, texts, and voices, and is also used to provide corresponding treatment methods. The complete tooth model database is established by scanning actual tooth data, and simulation of basic teaching in oral medicine, prosthetic dentistry, oral periodontology, oral implantology, and orthodontics, and clinical operation simulation are realized. By integrating the virtual reality technology with the oral cavity teaching, the high-efficiency oral cavity teaching system is provided.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and in particular relates to a virtual reality oral teaching system. Background technique [0002] Virtual reality is a combination of multiple technologies, including real-time three-dimensional computer graphics technology, wide-angle (wide-view) stereoscopic display technology, tracking technology for the observer's head, eyes and hands, and tactile / force feedback, stereo, network transmission, voice, etc. Input and output technology, etc. The evolution and development history of virtual reality technology can be roughly divided into four stages: before 1963, the simulation of sound, shape and dynamics was the first stage containing the idea of ​​virtual reality; (1963-1972) the germination of virtual reality was the second stage; ( 1973-1989) The emergence of the concept of virtual reality and the initial formation of the theory is the third stage; (1990-2004) the further improvement...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: firstly, the traditional teaching form is single, and the display form of text and two-dimensional images is single, and it is impossible to show a more complete three-dimensional and microstructure to teach students oral knowledge. Systematically and effectively grasp the key points of oral abstract knowledge; secondly, the field of virtual reality technology is not wide enough, and the existing oral teaching-style virtual reality content is even scarcer
