Embodiment Construction

[0073] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0074] As shown in Fig. 2, the image signal processing method of a kind of interactive multi-viewpoint video system of the present invention consists of a multi-viewpoint video imaging module at the system server end, an integrated multiviewpoint video encoding module, a partial code stream selection and transmission module, and a system user The terminal viewpoint decoding module, arbitrary viewpoint rendering module and video display module are used to complete the acquisition, encoding, transmission, decoding, rendering and display of image signals, and the integrated multi-viewpoint video encoding module performs multi-viewpoint image color correction and associated viewpoint parallax field Estimation and coding, block-based multi-viewpoint video coding, and viewpoint-decomposable structured stream generation. The user end transmits the vie...

Abstract

The invention discloses an image signal processing method for interactive multi-viewpoint video system, coding and storing multi-viewpoint video signal code streams and complete disparity field code streams between related viewpoints, obtained in different forecasting modes, and using fedback user end viewpoint selection information and display unit type information to properly select a viewpoint (used for single eye display) or two viewpoints (used for 3D display) or at most four viewpoints (used for 3D display of two virtual viewpoints) from the viewpoint-resolvable structural code streams, so as to implement partial transmission of multi-viewpoint video signals and reducing system's requirements for transmission bandwidth and requirements for user end system complexity, making it able to transmit more programs and service more users in the given network bandwidth and making the cost of a digital interactive multi-viewpoint TV receiver be lower.

Description

technical field [0001] The invention relates to a multi-viewpoint video system technology, in particular to an image signal processing method for an interactive multi-viewpoint video system. Background technique [0002] The interactive multi-viewpoint video system can provide users with multiple viewing angles of video content. Users can choose viewing angles according to their personal preferences, and change the viewing angles at will during the viewing process. Therefore, for an interactive multi-view video system, its basic goal is to effectively realize the viewpoint interaction between the user and the server. Generally, an interactive multi-view video system consists of the following parts: video capture, preprocessing, multi-view video encoder, multi-view video decoder, view rendering and display, as shown in Figure 1. For a multi-view video sequence captured by a group of cameras (or video cameras), there may be differences in brightness or chromaticity between vi...
