Embodiment Construction

[0030] A preferred embodiment of the three-dimensional image processing method of the present invention will be described in detail below with reference to the accompanying drawings. Please refer to figure 1 , figure 1 It is a schematic diagram of a 3D image processing architecture in a preferred embodiment of the present invention. The three-dimensional image processing method of the preferred embodiment of the present invention is used to convert a first image 10 located in a first viewing angle into a plurality of second viewing angles located in a plurality of second viewing angles through the encoder 120 and the decoder 140. Image 20. Specifically, the first viewing angle can be a left viewing angle or a right viewing angle. If the first viewing angle is a left viewing angle, the first image 10 is a left-eye image; if the first viewing angle is a right viewing angle, the first image 10 is a Right eye image. In fact, the encoder 120 receives the left-eye image and the ...

Abstract

The invention discloses a method for processing a three-dimensional image. The method is used for converting one first image of a first viewing angle into a plurality of second images of a plurality of second viewing angles, and comprises the following steps that a depth map is provided and corresponds to the first image, wherein the depth map comprises a plurality of gray scale pixels, and each gray scale pixel consists of a plurality of sub pixels; the capacity of the depth map is reduced to obtain a reduced depth map, and the reduced depth map only takes the single sub pixel to represent the single gray scale pixel; the first image and the reduced depth map are transferred to a decoder; and the second images are calculated in the decoder. By the method, the information compression ratio is increased, the purpose of reducing the information transmission quantity is realized, and moreover, a picture three-dimensional (3D) display effect is also optimized.

Description

technical field [0001] The present invention relates to an image processing method, in particular to a three-dimensional image processing method. Background technique [0002] In a three-dimensional (three-dimensional, 3D) naked-eye display, the 3D video coding technology is a key technology for realizing the transmission of multi-view images. Compared with traditional single-view two-dimensional (2D) video frame image coding, Multi-view Video Coding (MVC) has a larger amount of data and extremely high computational complexity. In order to overcome the huge transmission volume of multiple 2D images to generate multi-view images, multi-view video coding utilizes the correlation between different views, so it has a better compression rate than individual compression of a single view. Therefore, some people propose to use distributed video coding technology (Distributed Video Coding, DVC) to move complex calculations to the decoding side, so as to improve the coding performanc...
