Abstract

The embodiment of the invention provides a parallax calculation method and a device. The method comprises the following steps: obtaining a plurality of views of pixels; calculating the gradient of the pixel points in a plurality of directions in a plurality of views; calculating the matching error corresponding to the pixel point parallax according to the gradient; and calculating the parallax ofthe current pixel point according to the matching error. Through the parallax calculation method and the device provided by the embodiment of the invention, the parallax estimation accuracy is improve.

Description

technical field [0001] The invention relates to the technical field of three-dimensional video coding, in particular to a parallax calculation method and device. Background technique [0002] In a traditional single-view TV system, the user's viewpoint and angle of view are determined by the three-dimensional space position and direction of the camera. Therefore, the user cannot freely select the viewpoint and viewing angle for viewing. The Free Viewpoint Television (FTV: free viewpoint television) system proposed in 2002 allows users to freely choose the viewing point and angle of view to watch TV, thus providing a new, more vivid and realistic three-dimensional audio-visual system. [0003] A key technology of FTV is how to obtain accurate depth information, such as performing stereo matching (stereo matching) based on two views captured by two adjacent cameras, that is, disparity estimation. [0004] In the prior art, a global optimization algorithm is applied to dispar...
