Abstract

The embodiment of the invention relates to the technical field of image processing, in particular to an image rendering method, device and equipment for virtual reality and VR equipment. The image rendering method for virtual reality, based on an open graphics library, comprises the following steps: in response to a vertical synchronization signal, obtaining an image rendered by a 3D rendering thread and a first attitude transformation matrix of the 3D rendering thread by an anti-distortion thread; changing the first attitude transformation matrix according to acquired attitude parameters of the virtual reality equipment to obtain a third attitude transformation matrix; and subjecting the rendered image to anti-distortion processing through the third attitude transformation matrix, outputting, and displaying. According to the embodiment, the picture rendering time is shortened, and the display frame rate is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image rendering method for virtual reality, an image rendering device for virtual reality, an image rendering device for virtual reality, and a VR device. Background technique [0002] Virtual reality (abbreviated as VR) technology is a practical technology for computer simulation of virtual environment. Among them, VR glasses are a kind of head-mounted virtual reality device, and its work requires the display device to have high definition, high frame rate, and extremely low motion display delay (the time delay from the change of human action posture to the change of the picture). Therefore, the rendering technology to solve the above problems is the core of VR technology. At present, the rendering capabilities of mainstream mobile GPUs are difficult to meet the above requirements. There are some asynchronous warping and other technologies on the market to optimize ...
