The invention relates to a VR visual angle correction method, device and system and a storage medium. The method comprises the following steps: establishing a maintenance operation simulation picture;obtaining N-1 moving speeds according to the position coordinates of the display equipment at the N moments; processing according to the speed component of the moving speed in the three-dimensional coordinate system to obtain a correction speed; when the variation of the two adjacent correction speeds is greater than a preset speed, performing curve fitting on the position coordinates of the N moments to obtain view angle movement data; and adjusting the overhaul operation simulation picture according to the view angle movement data, and sending the adjusted overhaul operation simulation picture to the display device. By adopting the method, the position coordinates of the display equipment at N moments can be obtained; and processing to obtain correction rates corresponding to the movingspeeds, carrying out curve fitting on the coordinates of each position when the variation of two adjacent correction speeds is greater than a preset speed, and carrying out smoothing processing on the visual angle of the overhaul operation simulation picture to improve the stability of the visual effect.
Description
technical field [0001] The present application relates to the technical field of railway maintenance, in particular to a VR viewing angle correction method, device, system and storage medium. Background technique [0002] With the improvement of my country's railway science and technology level, the overhaul and maintenance of rolling stock and the information management of rolling stock are particularly important. In the railway maintenance training system, virtual reality (VR) technology is used to simulate the working environment and fault conditions of railway wagons, and guide trainees to carry out equipment maintenance according to maintenance standards. The operator can control the scene in the virtual scene to move to the pointing position through wearable devices and external sensors, and interact with the equipment in the 3D virtual scene for maintenance training. [0003] However, the current railway maintenance training system has poor visual stability and stude...
