Embodiment Construction

[0020] A kind of coding method of interactive multi-viewpoint video that the present invention proposes, in conjunction with accompanying drawing and embodiment detailed description is as follows:

[0021] An interactive multi-viewpoint video encoding method proposed by the present invention is characterized in that the video data of each channel synchronously collected by multiple cameras is divided into several viewpoint groups in turn according to the adjacent positions collected by them, and each viewpoint group viewpoint The number is the same (the number of viewpoints included in each group can be determined according to factors such as encoding server performance, network transmission bandwidth, and user requirements for video volume. Generally, an odd number is selected as the last group if the number of viewpoints is insufficient). For predictive coding, each viewpoint group is coded in the same way.

[0022] The above-mentioned viewpoint group adopts an inter-viewpoi...

Abstract

The method comprises: dividing video data in each channel collected by multi video cameras into multi viewpoint groups in term of their adjacent location in the collection; each viewpoint group has identical numbers of viewpoints; in each viewpoint group, using the predictive coding relating between the viewpoints; each viewpoint uses same coding approach.

Description

technical field [0001] The invention belongs to the technical field of information dissemination, and relates to an interactive multi-viewpoint video encoding method, in particular to the design of a multi-viewpoint video encoding prediction structure. Background technique [0002] Networking, interactivity and realism are the development direction of video technology. On the one hand, users hope to fully participate in video applications, and the relationship between humans and computers develops from passive to active, so as to fully realize the individual needs of each person; on the other hand, the real world is a three-dimensional environment, and traditional video mainly Based on the two-dimensional expression, although the three-dimensional information is expressed to some extent, the user requires a more realistic experience and feeling. Multi-viewpoint video is proposed for such interactive video applications, covering binocular stereoscopic video and multi-viewpoi...
