3D (three-dimensional) video signal compression coding-decoding method, device and system

Abstract

The invention is suitable for the field of multimedia information processing and provides a 3D (three--dimensional) video signal compression coding-decoding method, device and system. The compression coding method comprises the following steps: obtaining an odd pixel value or an even pixel value of a left eye video image and an odd pixel value or an even pixel value of a right eye video image of an original 3D video signal; and generating a hybrid video image according to the odd pixel value or even pixel value of the left eye video image and the odd pixel value or even pixel value of the right eye video image. The size of the newly generated hybrid video image is the same as that of the left or right eye video image so as to solve the problem of insufficient transmission bandwidth; and meanwhile, various frequency components of the left and right eye video images are completely preserved to reduce the distortion of the images, and the relativity of the left eye video image and the right eye video image is basically preserved so that the efficiency of coding and decoding the transmission format of the hybrid video image is high, and the compression ration is high.

Description

technical field [0001] The invention belongs to the field of multimedia information processing, and in particular relates to a method, device and system for compressing and encoding 3D video signals. Background technique [0002] With the widespread application of 3D video, 3D movies, etc., 3D technology is becoming more and more popular. 3D technology is based on the principle of binocular parallax and the visual characteristics of the human eye. Two images with a certain angle are projected into the left and right eyes of the person respectively, so that the human brain forms an image with a certain sense of depth, thereby forming a 3D stereoscopic effect. display effect. Therefore, in order to achieve a 3D stereoscopic display effect, two video images (a left-eye video image and a right-eye video image) must be displayed simultaneously within a certain period of time. However, the current video transmission system is limited by physical conditions such as system bandwidt...
