Problems solved by technology

[0003] The disadvantage of this format is that since the 2D image and the depth image each account for half, the information of the 2D image is compressed by half in the horizontal direction, while the depth image on the right is only a grayscale image, occupying three channels of RGB, which appears unbalanced. while wasting space

Embodiment Construction

[0037] Specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0038] Unless expressly stated otherwise, throughout the specification and claims, the term "comprise" or variations thereof such as "includes" or "includes" and the like will be understood to include the stated elements or constituents, and not Other elements or other components are not excluded.

[0039] Such as Figure 3-4 Shown, a kind of 2D plus depth 3D image longitudinal storage method based on RGB compression, its steps are:

[0040] (1) Divide the screen with a resolution of 1920╳1080 into three equal parts vertically, and then divide the lower part into two equal parts horizontally;

[0041] (2) Compress the 2D color image vertically to 2 / 3, and then place it in the 1920╳720 area, where the top-half Color is placed in the top 1920╳360 area, and the bottom-half...

Abstract

The invention discloses a 2D plus depth3D image vertical storage method based on RGB compression. An image having a resolution ratio of A*B is vertically and equally divided into three parts, and the lower part is horizontally and equally divided into two parts. The 2D colorful image is vertically compressed to be two thirds of the original size, and then is disposed in the A* 2 / 3B area, and in addition, the top-half color is disposed in the A*1 / 3B area of the top part, and the bottom-half color is disposed in the A*1 / 3B area of the middle part. The depth image is vertically compressed to be two thirds of the original size, and then is disposed in the A*1 / 3B area of the lower part after being compressed by the RGB channel, and in addition, the depth image corresponding to the top-half color is disposed in the 1*2A*1 / 3B area of one side of the lower part, and the depth image corresponding to the bottom-half color is disposed in the 1 / 2A* 1 / 3B area of the other side of the lower part. The 2D plus depth image is converted into a multi-view view by a conversion circuit or a conversion software. The 3D display image quality is greatly improved without causing any other costs.

Description

Technical field: [0001] The invention belongs to the technical field of image processing, and in particular relates to a longitudinal storage method for 2D-enhanced 3D images based on RGB compression. Background technique: [0002] At present, the format of 3D display source files based on 2D plus depth is mostly 2D and depth image formats with half on the left and half on the left. Such as figure 1 As shown, if the resolution of the target display screen is AxB, and the image to be displayed is a 2D AxB and an AxB depth map, first divide the display area into two symmetrical parts, each of which is 0.5AxB. Compress the 2D color image by half horizontally and place it in a 0.5AxB area on the left, and then compress the depth image by half horizontally and place it in a 0.5AxB area on the right. The 2D depth-enhanced image is converted into a multi-view view through a proprietary circuit or software. [0003] The disadvantage of this format is that since the 2D image and t...
