Embodiment 1

[0039] Such as figure 1 As shown, the 4K video optimization method in virtual reality of the present invention comprises the following steps:

[0040] Step S101: In the virtual reality engine, according to the position of the decoded 4K video on the screen in the virtual reality scene and the frame size of the screen, anti-distortion processing is performed on the decoded 4K video without scaling ;

[0041] In the method of the present invention, before the decoded 4K video is placed on the screen in the virtual reality scene, it is necessary to perform anti-distortion processing on the video to adapt to the position and size of the screen in the virtual reality scene, but it is different from the prior art What is interesting is that in the prior art, the decoded 4K video is subjected to anti-distortion processing and zooming at the same time before delivery. In the present invention, only anti-distortion processing is performed without scaling, so that the loss of video pi...

Embodiment 2

[0046] Such as figure 2 As shown, the 4K video optimization method in virtual reality of the present invention is described in more detail, and the method includes the following steps:

[0047] Step S201: Obtain the recorded 4K video, and decode the 4K video.

[0048] 4K video refers to a video with a resolution of 4096×2160 (width×height), that is, there are 4096 pixels horizontally and 2160 pixels vertically, and its total pixels exceed 8 million, which is 4 times the resolution of 2K projectors and high-definition TVs. (The resolution of 2K digital movies is roughly equivalent to that of HDTV, which is 1920×1080). 4K video in the true sense refers to digital video shot with a 4K camera and projected with a 4K projector.

[0049] Step S202: In the virtual reality engine, perform anti-distortion processing on the decoded 4K video without zooming according to the position of the decoded 4K video on the screen in the virtual reality scene and the frame size of the screen ;

Embodiment 3

[0060] Such as image 3 As shown, the 4K video optimization device in virtual reality of the present invention is described in detail, including:

[0061] The video anti-distortion module 31 is used in the virtual reality engine to perform anti-distortion on the decoded 4K video according to the position on the screen in the virtual reality scene and the size of the screen frame that the decoded 4K video needs to be placed on. processed without scaling;

[0062] The synthesis and delivery module 32 is configured to synthesize the anti-distortion processed video and the rendered scene after the scene rendering is completed, and perform picture delivery and output to the screen of the virtual reality device.

[0063] Preferably, it also includes:

[0064] The video decoding module 33 is configured to obtain the recorded 4K video and decode the 4K video.

[0065] Preferably, the video anti-distortion module 31 is further configured to perform anti-distortion processing on the ...

Abstract

The invention discloses a virtual reality 4K video optimization method and device. The method comprises the steps that step A: anti-distortion processing is performed on a decoded 4K video and zooming is not performed in a virtual reality engine according to the position of projection of the decoded 4K video on the screen of a virtual reality scene and the size of the frame of the screen; and step B: after completion of scene rendering, the video after anti-distortion processing and the rendered scene are synthesized, and the frames are delivered and outputted to the screen of virtual reality equipment. Anti-distortion processing is performed on the video and zooming is not performed before the video texture is pasted on the screen of the virtual reality scene, the video is deformed into the shape suitable for playing of the screen of the virtual reality scene, and finally the video and the scene are directly synthesized in the process of synthesis of the video and the scene and delivery to the screen of the virtual reality equipment so that the problem of the fuzzy frames caused by reducing the 4K video and then zooming the 4K video can be avoided.

Description

technical field [0001] The present invention relates to the technical field of virtual reality, in particular to a method and device for optimizing 4K video in virtual reality. Background technique [0002] The primary application of virtual reality has been understood and recognized by a large number of users in the past two years, and there are already some video playback and demand based on virtual reality, such as watching videos played on the screen of a cinema in a virtual cinema. However, due to the limited resolution of existing devices, how to improve the display quality as much as possible under the existing resolution is an urgent problem to be solved. [0003] The premise of this problem is that the resolution of the existing virtual reality equipment is high resolution, such as 4K, but due to the limited rendering capability of the GPU (Graphics Processing Unit, graphics processing unit), the single-eye resolution of the actual virtual reality scene may only be ...
