Embodiment Construction

[0053] In order to better understand the technical solutions provided by the embodiments of the present application, the technologies or names involved in the embodiments of the present application are firstly introduced.

[0054] (1) panoramic video stream

[0055] Panorama (panorama) is to stitch one or more groups of photos taken by the camera ring 360 degrees into a panoramic image. In other words, the panoramic image may include images within a 360-degree range centered on the camera. Panoramic images can be displayed through dedicated playback software. If displayed on a desktop computer or laptop, the user can operate the mouse to control the direction of viewing; if displayed on a mobile terminal such as a mobile phone or tablet, the user can control the direction of viewing through sliding operations . The direction of looking around can be left or right, and objects or scenes can be viewed near or far.

[0056] Panoramic video stream is to splice multiple video st...

Abstract

The embodiment of the invention provides a video processing method, device and system, which are used for splicing videos in the field of virtual reality. The method comprises the following steps: determining shooting demand parameters required by video stitching; acquiring a first group of shooting parameter information matched with the shooting demand parameter; acquiring a first video stream matched with the first group of shooting parameter information; and generating a first panoramic video stream according to the first group of shooting parameter information and the first video stream. According to the embodiment of the invention, the dependence on operators can be reduced, and the generation efficiency of the panoramic video stream can be improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of virtual reality, and in particular, to a video processing method, device, and system thereof. Background technique [0002] Virtual reality (virtual reality, VR) live broadcast, using a specific panoramic camera or equipment and video stitching algorithm or software, can upgrade the common two-dimensional flat video to a three-dimensional panoramic video. The user's viewing angle is no longer limited to a fixed screen box, but changes with the change of the viewing angle, bringing a brand-new visual experience to the user, and giving the video content a new display form. VR live streaming can be applied to the film and television media industry, medical industry, tourism industry, real estate industry, shopping and consumption industries, etc., bringing visual experience and convenience to work, life, and entertainment. [0003] At present, the content generation process of VR...
