Problems solved by technology

Under the same definition requirements, the data volume of VR video is more than ten times that of ordinary video, and storage and transmission are difficult
[0006] In order to compress the data volume of VR video, the existing technology reduces the file size by reducing the definition of secondary parts in the image, but the inventors found that this compression method can only reduce the data volume to a limited extent, and actual

Example Embodiment

[0072] Example 1

[0073] like figure 1 , image 3 , Figure 4 , Figure 5 with Image 6 As shown in a VR video data compression method, comprising:

[0074] The VR camera is fixed in the field center of the scene to generate a VR video 1; divide the 1 VR screen into a different target area according to the complexity of the change in timeline to different target regions to perform different density recording sampling;

[0075] The target area 2 of the complex movement or change is recorded as a dynamic 3D video;

[0076] The original video information 8 of the target area 3 that is simple or repeated motion is recorded as a short video 9 that covers a period of time, and the short video is played to the time line when viewed.

[0077] The original video information 10 of the target area 4 that is slow-moving is recorded in the timeline to reduce the frame rate video 11, and the video slowly plays this video to fill the timeline.

[0078] The original video information 12 of the station...

Example Embodiment

[0080] Example 2

[0081] like figure 2 , image 3 , Figure 4 , Figure 5 with Figure 7 As shown, a method of compressed VR video data, including:

[0082] Select the scene to be taken, determine the center of the scene as the position of the camera device; divide the VR screen corresponding to the scene into different target regions in different densities in the time line, to perform different density recording sampling;

[0083] Use the eight-purpose VR camera 7 to cover the short video 9 of the simple or repeated motion of the target area 3 to cover a time line, and then play this short video to fill the timeline.

[0084] Use the eight-purpose VR camera 7 to shoot a single frame picture 13 of the stationary target area 5, and the picture continuously presents this picture to fill the timeline when viewing;

[0085] Target area 2 with complex motion or change is recorded as dynamic 3D video with 3D camera 6.

[0086] Turning this video 11 with a 3D camera 6 to reduce the video 11...

Abstract

The invention belongs to the technical field of video data processing, and particularly relates to a method for compressing VR video data, and the method comprises the steps: carrying out the sampling and recording of a part of or all regions of a VR visual field on a timeline as any one or a combination of a single-frame picture, a short video covering a time line, and a video with a reduced frame rate, sending the sampling result to the client and filling the timeline in any one or more combination modes of continuous playing, loop playing and slow playing; sampling a part of the region in the VR visual field into a 3D video, sending the 3D video to a client, and playing the 3D video. By means of the compression method, high definition can be kept while efficient data compression is achieved, and the watching effect is prevented from being reduced.

Description

technical field [0001] The disclosure belongs to the technical field of video data processing, and in particular relates to a method for compressing VR video data. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Virtual reality (VR) video refers to 3D panoramic video that can be viewed in a VR head-mounted display. VR video has both three-dimensional and surround effects, which can bring immersive experience to movie viewers. It has been widely used in leisure and entertainment, product display and online teaching and other fields. [0004] According to the generation method and data structure of VR video, it can be divided into VR video of real scene shooting and VR vid...
