Method for encoding stereo video

Abstract

The invention discloses a three-dimensional video encoding method. The method has the advantages that: the encoding quality of an image is changed by changing a quantization parameter, thus changing the code rate of the image, so as to adapt to the changing of the network transmission bandwidth; under the condition of high bandwidth, a left-viewpoint basic-layer code stream, a left-viewpoint enhancement-layer code stream, a right-viewpoint basic-layer code stream and a right-viewpoint enhancement-layer code stream are transmitted at the same time, thus acquiring high-quality videos; under the condition of low bandwidth, however, only the left-viewpoint basic-layer code stream and the right-viewpoint basic-layer code stream are transmitted, a client can also normally decode and acquire low-quality videos, thus leading good network adaptability of the method; as an automatic three-dimensional display device can synthesize the video which is corresponding to the present viewing angle by the existing viewpoint video when the viewing angle is changed, namely the virtual viewpoint synthesis. The method leads an automatic three-dimensional display terminal of users to be capable of quickly realizing the virtual synthesis of multi-viewpoint images with low complexity by providing the parallax field code stream for the client, thus satisfying the requirement of real-time automatic three-dimensional displaying.

Description

technical field [0001] The invention relates to a video signal encoding and compression method, in particular to a stereoscopic video encoding method. Background technique [0002] Compared with two-dimensional (2D, Two Dimensional) video display, stereoscopic / three-dimensional (3D, Three Dimensional) video display matches people's vision better, and it makes people have a sense of three-dimensionality and immersion when watching images on the screen. In recent years, the governments of the United States, Europe, Japan, and South Korea have invested huge sums of money in the research and development of three-dimensional television / three-dimensional television (3DTV, ThreeDimensional Television), including the National Natural Science Foundation of the United States, the U.S. Department of Naval Research and Energy, the U.S. Advanced The Visual Technology Center of the European Union, the 3DTV plan of the European Union's sixth framework agreement, the European Union's ESPRIT...
