Application research of image preprocessing based on MR (Mixed Reality) system of rail vehicles

Mixed reality technology (MR) combines the advantages of virtual reality (VR) and augmented reality (MR), by introducing the real scene information in the virtual environment. The real space is first scanned and recognized, and then the virtual scene is fully integrated into the real space. In MR (Mixed reality) system of rail vehicle, users wear mixed reality equipment, mobile video capture, after image processing, combined with multi-modal human-computer interaction knowledge base and constraint control theory, to achieve the control of virtual equipment and scene of rail vehicle and the best practical teaching effect. In this paper, by studying the method of rapid real-time preprocessing of image acquisition, it lays a solid foundation for the complex image processing of rail vehicle MR (mixed reality) system.
