Problems solved by technology

[0004] The disadvantage of the existing Shuangpin 3D video coding method is that it adopts the traditional single-view coding framework for processing, without considering the characteristics of the Shuangpin attribute of the signal source, so it is impossible to obtain the optimal coding effect

Abstract

The invention provides a method and device for coding two paths of three-dimensional videos, wherein the method comprises the following steps of: splicing two paths of three-dimensional videos to obtain a binary syllabification sequence; in the term of the two paths of three-dimensional videos, carrying out rate distortion optimization coding on the binary syllabification sequence; and reconfiguring the coded binary syllabification sequence to obtain a coding result of each path of video. Through changing a distortion measurement selected by a macro block mode, the rate distortion performance of coding the two paths of three-dimensional videos is improved, and an optimal image coding effect is obtained.

Description

technical field [0001] The invention relates to the technical field of stereoscopic video processing, in particular to a method and device for encoding two-way stereoscopic video. Background technique [0002] In recent years, with the popularization of 3D applications, the research on stereoscopic images and videos has become a hot spot, and the applications related to images and videos have also been continuously expanded, such as digital TV broadcasting, video on demand, distance education and medical care, wireless multimedia communications, etc. . Since the data volume of the original image and video is very large, and the bandwidth cannot be increased without limit, in order to use the limited bandwidth to complete the image transmission of large data volume, it is necessary to use effective video compression technology. [0003] Currently, a two-view stitching technique for stereoscopic video is proposed. Compared with the separate transmission of two channels of vi...
