Abstract

The invention is suitable for the field of image processing, and provides a method and device for smoothening a disparity map and electronic equipment. The method comprises the following steps: initializing A(z, y), B(x, y) and F(x, y) into all-zero matrixes; acquiring all pixel points (x<k>, y<k>) satisfying S(x, y)=k in S(x, y); making A(x<k>, y<k>)=M(x<k>, y<k>), B(x<k>, y<k>)=1; computing all A(x<k>-i, y<k>-i) and T(x<k>, y<k>) taking x<k>, y<k> as a center; computing the sum of all B(x<k>-i, y<k>-i) taking x<k>, y<k> as a center to obtain the quantity T(x<k>, y<k>) of all the pixel points satisfying S(x, y); and computing F(x<k>, y<k>) according to T(x<k>, y<k>) and T(x<k>, y<k>). Through adoption of the method and device for smoothening the disparity map and the electronic equipment, the smoothness or continuity of disparity is realized, and the sudden change or discontinuity of an object edge is kept.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method, device and electronic equipment for smoothing a parallax map. Background technique [0002] A 3D image usually consists of two paths, each corresponding to a specific viewing angle. In order to generate an image corresponding to a new viewing angle, it is necessary to calculate a disparity map based on the input image, that is, to calculate the correspondence between the two images. The calculation step generally includes two steps, the first step is to estimate the disparity map; the second step is to optimize the result of the first step, usually through various smoothing algorithms to optimize the result of the first step. [0003] Smoothing of the disparity map is a dilemma. On the one hand, we want the disparity of an object to be smooth or continuous; on the other hand, at the edge of the object, we want to preserve its possible abrupt chang...
