Embodiment Construction

[0051] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] Interactive 3D video systems such as figure 1 As shown, it is mainly composed of a 3D video encoding module on the server side, a viewpoint decoding module on the user side, an arbitrary viewpoint rendering module and a video display module. A signal processing method in an interactive three-dimensional video system proposed by the present invention comprises the following steps:

[0053] ① Acquire K color images of K reference viewpoints at time t whose color space is YUV and their corresponding K depth images, and record the color image of the kth reference viewpoint at time t as Denote the depth image of the kth reference viewpoint at time t as Among them, K≥2, 1≤k≤K, the initial value of k is 1, i=1, 2, and 3 respectively represent the three components of the YUV color space, and the first component of the YUV color space is the...

Abstract

The invention discloses a signal processing method of an interactive three-dimensional video system. The signal processing method comprises the following steps of: firstly, taking multiple virtual viewpoints between each two adjacent reference viewpoints as auxiliary viewpoints, obtaining the residual image of each auxiliary view point, then encoding each color image, each depth image and each residual image by using a three-dimensional video coding module of a server, transmitting each color image, each depth image and each residual image to a user side, decoding each coded image by using a viewpoint decoding module of the user side, finally generating reference viewpoint signals and auxiliary viewpoint signals by any viewpoint drawing modules, and transmitting the reference viewpoint signals and the auxiliary viewpoint signals to a video display module for display. The signal processing method has the advantages that as the server only needs to transmit the residual images containing less information content as the auxiliary viewpoint information, the coding complexity of the system server is reduced, and as virtual viewpoint signals can be generated at the server only through simple three-dimensional mapping and add operation, the requirements on user side systems are reduced, thus the complexity of the interactive three-dimensional video system is reduced.

Description

technical field [0001] The invention relates to a multi-viewpoint video system technology, in particular to a signal processing method in an interactive three-dimensional video system. 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 interactive 3D video system is more and more popular because it can provide a brand-new visual experience with three-dimensionality and viewpoint interaction. It has broad application prospects. [0003] For the performance evaluation of 3D video coding, there are usually multiple technical indicators, such as rate-distortion pe...
