Embodiment 1

[0020] figure 1 It is a flowchart of a virtual reality scene rendering method according to an embodiment of the present invention, such as figure 1 as shown,

[0021] In step S110, the image processor receives the distortion data, and stores the distortion data in a register of the image processor;

[0022] In step S120, during the process of converting the virtual reality scene to be rendered into a two-dimensional image, the image processor performs distortion processing on the virtual reality scene to be rendered according to the distortion data, and converts the A 2D image is rendered to the screen.

[0023] pass figure 1 It can be seen from the method shown that the technical solution of the present invention saves the distortion data in the register of the image processor, and in the process of converting the virtual reality scene to be rendered into a two-dimensional image by the image processor, according to the distortion data The virtual reality scene is distorte...

Abstract

The invention discloses a virtual reality scene rendering method, an image processor and head-mounted display equipment. The method comprises the steps that the image processor receives distortion data and stores the distortion data in the register of the image processor; and the image processor performs distortion processing on a virtual reality scene to be rendered according to the distortion data in the process of the converting the virtual reality scene to be rendered into a two-dimensional image and renders the two-dimensional image after distortion processing on a screen. Compared with the method in the prior art that a three-dimensional scene requires to be rendered into the two-dimensional image in a hardware layer and then distortion processing is performed on the two-dimensionalimage in a software layer and then the two-dimensional image is projected to the screen, the operation of the software layer can be omitted, interaction of software and hardware can be reduced, the delay time can be reduced and the user experience can be enhanced.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to a virtual reality scene rendering method, an image processor and a head-mounted display device. Background technique [0002] When a virtual reality (Virtual Reality, VR) device presents a three-dimensional scene or object for the user, it mainly renders the three-dimensional scene or object into a two-dimensional image at the bottom layer of the hardware, and then uploads the two-dimensional image to the software layer, where the two-dimensional After distorting the 2D image, the distorted 2D image is finally projected to the screen. The whole process requires interaction between software and hardware, which takes a certain amount of time during the interaction between software and hardware, resulting in long delays and poor user experience. Contents of the invention [0003] The present invention provides a virtual reality scene rendering method, an image processor a...
