Live broadcast method at dynamic viewing angle of 0-360 degrees

Abstract

The invention discloses a live broadcast method at a dynamic viewing angle of 0-360 degrees. The method comprises the following steps: firstly, acquiring a 360-degree panoramic image through a 360-degree panoramic camera; then, cutting the 360-degree panoramic image; reserving a required visual angle scene of any angle between 0 degree and 360 degrees as a visual area; replacing the cut image datawith black, setting the black image data as a shielding area, transmitting the data of the visible area part and the data of the shielding area part to a cloud server after the data of the visible area part and the data of the shielding area part are encoded by an encoder for video encoding, and obtaining a viewable video at any angle between 0 degree and 360 degrees through video decoding and 360-degree video rendering. The 360-degree panoramic camera is used for collecting 360-degree videos, the videos at any angle of 0-360 degrees are achieved through a video cutting and filling algorithmand a video center point moving algorithm, then 360-degree impression experience is achieved through a video encoding and decoding technology, the phenomena of image splicing, ghosting and the like can be avoided, and the impression of a user is improved.

Description

technical field [0001] The invention relates to a live broadcast method, in particular to a 0-360° dynamic viewing angle live broadcast method. Background technique [0002] At present, most VR video live broadcasts use 360° panorama equipment. Generally, 360° video capture equipment has 6 lenses, and the six images need to be spliced ​​before they can be displayed as 360° viewable scenes on the VR display terminal. The problems caused by the splicing algorithm are: [0003] One is that the images in the middle of the two spliced ​​images are superimposed, and the superimposed images are deformed; [0004] The second is that the people and objects in the image have ghosting phenomenon; [0005] Third, the resolution of VR videos is relatively large, and the generated images are generally 3K, 4K and above. Therefore, the bandwidth during real-time transmission generally needs to be above 20Mbps to achieve ideal viewing clarity. [0006] At present, it is difficult for ordi...
