Problems solved by technology

[0003] However, compared with the color image, the texture of the depth image is simple, which includes more flat areas, but due to the limitations of the depth image acquisition algorithm, the depth image generally has problems such as poor time continuity and depth discontinuity.

Embodiment Construction

[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0068] A kind of deep image encoding method proposed by the present invention, its flow chart is as follows figure 1 As shown, it specifically includes the following steps:

[0069] ①Define the unprocessed color stereoscopic video with color space YUV and its corresponding depth stereoscopic video captured by an external stereoscopic video capture tool as the original 3D stereoscopic video. The original 3D stereoscopic video consists of the original left viewpoint color image, the original Right viewpoint color image, original left viewpoint depth image and original right viewpoint depth image, the original left viewpoint color image at time t is recorded as The original right-viewpoint color image at time t is recorded as Denote the original left-viewpoint depth image at time t as Denote the original right-view depth image at time t as ...

Abstract

The invention discloses a depth image coding method which is characterized in that a maximum tolerable distortion distribution image of an original left viewpoint depth image is obtained according to influence of depth distribution on virtual viewpoint image drawing and by combining the visual characteristics of human eyes, a drawing image of an original right viewpoint depth image is obtained in the method based on depth image drawing, the original left viewpoint depth image is coded according to the maximum tolerable distortion distribution image and the set coding forecast structure to obtain a decoded left viewpoint depth image, the original right viewpoint depth image and a residual image of the drawing image of the original right viewpoint depth image are coded according to the set coding forecast structure to obtain a decoded residual image, and finally a reconstructed image of a decoded right viewpoint depth image is obtained according to a drawing image of the decoded right viewpoint depth image and the decoded residual image. The depth image coding method has the advantage of greatly improving depth image coding efficiency on the basis of ensuring virtual viewpoint image drawing performance.

Description

technical field [0001] The invention relates to a video signal encoding and compression method, in particular to a depth image encoding method. Background technique [0002] Since the beginning of this century, with the digital 2D (two-dimensional) video technology becoming more and more mature, as well as the rapid development of computer, communication and network technology, people have a strong demand for a new generation of video systems. The current two-dimensional video system is difficult to meet the user's needs for three-dimensionality and viewpoint interaction when representing natural scenes. The 3D video system is more and more popular because it can provide a brand-new visual experience with three-dimensional sense and viewpoint interaction. Application prospects. Compared with single-channel video, 3D video needs to process at least twice the amount of data. Therefore, it is an urgent problem to reduce the coding rate of 3D video as much as possible without ...
