A VR rendering method, device, wearable device and readable storage medium

Abstract

The invention provides a VR (Virtual Reality) rendering method and device, a wearable device and a readable memory medium. A left eye scene image and a right eye scene image are obtained; the left eyescene image and the right eye scene image are rendered on a texture image; and anti-distortion processing is carried out on the target image through adoption of an anti-distortion mode based on gridvertices. According to the process, the scene images of two eyes are rendered on the texture image, so the texture image only needs to be transmitted once. Compared with a mode of transmitting the texture images twice in the prior art, the mode has the advantages that the consumed time is reduced. According to the method, the device, the wearable device and the readable memory medium, the anti-distortion mode based on the grid vertices is employed, so each pixel does not need to be processed independently, the distortion processing is carried out on vertices of relatively sparse grids, the computing quantity is greatly reduced, the consumed time is reduced, and the anti-distortion processing efficiency is improved. Compared with the prior, the method, the device, the wearable device and the readable memory medium have the advantages that the consumed time in a VR rendering process is greatly reduced, and the VR rendering efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a VR rendering method, device, wearable device and readable storage medium. Background technique [0002] Virtual reality (Virtual Reality, VR) is a high-tech emerging in recent years. VR is a comprehensive integrated technology, involving computer graphics, human-computer interaction technology sensor technology, artificial intelligence and other fields. It uses computer-generated realistic 3D audio-visual to make people, as participants, experience and interact with the virtual world naturally through appropriate devices. VR mainly has three meanings: first, virtual reality is a realistic entity generated by computer, and "entity" refers to people's senses (audio, hearing, touch, smell); For environmental interaction, natural skills refer to other human body movements such as head turning, eye movement gestures, etc. Third, virtual reality often requires the h...

Problems solved by technology

[0003] As far as the current VR experience is concerned, the most urgent problem to be solved is the physical discomfort such as dizziness during user experience. There are many reasons for physical discomfort, such as resolution, image ghosting, image delay, and discontinuous depth perception. Wait

Taking games as an example, usually a game’s frame rate can be kept above 30 frames per second to meet the player’s needs for a smooth game, but for VR immersive experience, 30 frames per second is far from enough. If the frame rate is too low, the picture delay will be too long, and the rendered scene that the user actually sees will be displayed "one pause at a time", which will increase the discomfort of the VR experience and even make people feel dizzy.

Generally speaking, the delay needs to be less than 20ms and the smaller the better, so as to ensure a better VR experience. If you want the delay to be less than 20ms, you must ensure that the frame rate reaches at least 75 frames per second, or even 90 frames per second. Above, and this kind of performance requirements, even the current mainstream home PCs are difficult to meet
