Embodiment 1

[0072] Such as figure 1 The flow chart of the method for compressing and encoding a 3D video signal provided by the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0073] In step S101, the odd or even pixel values ​​of the left-eye video image and the odd or even pixel values ​​of the right-eye video image of the original 3D video signal are acquired.

[0074] In the embodiment of the present invention, the original 3D video signal includes a left-eye video image and a right-eye video image.

[0075] In the embodiment of the present invention, the original 3D video is stored in the form of matrix, that is, the value of each pixel is stored in the form of matrix. Therefore, the pixel values ​​of the left-eye video image and the right-eye video image of the original 3D video signal are respectively stored in two matrices of the same size. When the sum of the row and column where ...

Embodiment 2

[0092] Such as Figure 5 The flow chart of the method for compressing and decoding a 3D video signal provided by the present invention is shown, and for the convenience of description, only the parts related to the embodiment of the present invention are shown.

[0093] In step S501, the transmission format of the mixed video image is decoded.

[0094] In the embodiment of the present invention, the decoding end decodes the transmission format after receiving the mixed video image. Any method may be used to decode the transmission format of the mixed video image, and the transmission format decoding method is not limited here.

[0095] In step S502, the mixed video image is decompressed and decoded to obtain a primary left-eye video image and a right-eye video image.

[0096] In the embodiment of the present invention, the decompression and decoding of the mixed video image is specifically: filling the left-eye odd pixel value or even pixel value of the mixed video image into...

Embodiment 3

[0113] In the embodiment of the present invention, the even pixel value of the left-eye video image is used as the even pixel value of the mixed video image, and the odd pixel value of the right-eye video image is used as the odd pixel value of the mixed video image, thereby forming a mixed video image As an example, to describe in detail how to combine the odd pixel value or even pixel value of the left-eye video image of the original 3D video signal and the odd pixel value or even pixel value of the right-eye video image to form a mixed video image to complete the compression encoding of the 3D video image , but not limited to this way of composing mixed video images.

[0114] Such as Image 6 Shown is the specific implementation steps of using the even pixel value of the left-eye video image as the even pixel value of the mixed video image, and using the odd pixel value of the right-eye video image as the odd pixel value of the mixed video image. For the sake of illustratio...

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 simultaneously displayed within a certain period of time. However, the current video transmission system is limited by physical conditions such as system bandwidt...
