Problems solved by technology

For example, to reach the desired video angle, you need to operate the button 5 times, and the server will also extract and push the video data in the first four times, which greatly increases the computing pressure on the server and increases the communication between the server and the video terminal. transmit traffic

Abstract

The invention discloses a playing method and a playing system of an interactive multi-view video. The method comprises the steps that a video terminal transmits a video request including a video identifier to a server; the video terminal receives a 3D (Three-Dimensional) model and a panoramagram of a video site corresponding to the video identifier fed back by the server; the video terminal receives a virtual viewpoint selected by the 3D model, and displaying the panoramagram corresponding to the virtual viewpoint; and the video terminal obtains video data corresponding to the virtual viewpoint, and plays the obtained video data. According to the technical scheme of the playing method, the operation pressure of the server can be reduced effectively, and the occupation of flow transmission between the server and the terminal can be reduced.

Description

technical field [0001] The invention relates to video processing technology, in particular to a method and system for playing interactive multi-view video. Background technique [0002] With the continuous upgrading of video services, the simple visual information provided by traditional video can no longer meet the demand. Facing the diverse world around us, we need to observe and analyze from a more comprehensive and three-dimensional perspective. Thus, multi-view video technology came into being. Compared with traditional single-point video, multi-view video can provide information from different angles of a certain object or scene, and these information can be synthesized to generate multi-angle, all-round free or stereoscopic vision. [0003] The original data of the multi-view video is generally collected by a collection of multiple cameras, and different types of multi-view video data are generated according to different arrangements of the cameras. Since most of t...
