Abstract

The invention provides a disparity map generation method and a system. the disparity map generation method comprises steps: a depth map for an image with depth information is acquired; the depth value of each pixel RGB, the depth value of the farthest RGB and the depth value of the nearest RGB in the depth map are acquired, and the depth value of each pixel in the depth map is obtained; according to the depth value of each pixel in the depth map, a disparity value of each pixel in the depth map is obtained; and according to the disparity value of each pixel in the depth map, a disparity map for forming a 3D image is obtained. The accurate disparity map can be generated so as to display a 3D image with good 3D effects, the disparity map acquisition process has stronger universality, the steps are concise, and generation of the disparity map on different platforms can be realized.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a method and system for generating a disparity map. Background technique [0002] At present, one of the principles of forming a 3D image is that an image with depth information and a parallax map are needed, and the two images are interleaved by software to form a new image, and finally a three-dimensional effect is formed through a 3D optical prism, which the human eye can see will have 3D images. The left-eye and right-eye images with parallax are called a disparity map for stereoscopic display, then the parallax value is a key factor affecting the 3D effect, and the disparity map is closely related to the depth map (Depth Map). The existing process of converting a depth map to a disparity map is cumbersome, and the corresponding coefficients need to be modified in different situations. It cannot be applied to multiple situations at the same time. Extracting depth data...
