Problems solved by technology

[0005] In the image display process, the frame rate of the image displayed on the monitor is usually fixed. The frame rate refers to the number of times the displayed image is updated per second. The frame rate is, for example, 60Hz or 120Hz. However, under the current hardware architecture, the image rendering capability of the GPU is limited. Certain restrictions, when the image rendering capability of the GPU is insufficient, it is easy to cause the problem that the image display is not smooth

Abstract

The invention provides a virtual reality image display method and device and virtual reality equipment. The method can be applied to the virtual reality equipment. The method comprises the steps thata latest rendering-completed image is acquired; a first head pose after first preset duration is predicted based on an acquired first current head pose, wherein the first preset duration is duration required for performing first time warping processing on the latest rendering-completed image; first time warping processing is performed on the latest rendering-completed image according to the firsthead pose to obtain a first warped image matched with the first head pose; and the first warped image is output into a display cache, so that the first warped image is displayed when a vertical synchronization signal Vsync of a current frame is received. Through the method, display delay of the image can be shortened, and the smoothness of a display picture can be improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a virtual reality image display method and device thereof, and a virtual reality device. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) technology is a computer simulation technology that can create and experience a virtual world. It combines computer technology and display technology to construct a virtual environment that allows users to immerse themselves in the virtual environment. Strong sense of immersion. [0003] In order to achieve a three-dimensional display effect, the image frame rate of the display screen of a virtual reality device is usually higher than that of an ordinary display. The frame rate of the display screen refers to the number of times the image displayed on the display screen is updated per second, and its unit is Hertz ( Hz). [0004] The display system of a VR device generally includes a central process...
