Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see Figure 1~4 , in the embodiment of the present invention, a 0-360° dynamic angle of view live broadcast method, firstly, a 360-degree panoramic image is collected through a 360-degree panoramic camera, and then the 360-degree panoramic image is cut to retain the required 0-360-degree The viewing angle scene at any angle between is the visible area, replace the cut image data with black, set it as a shielding area, and transmit the data in the visibl...

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...
