Embodiment approach

[0043] In the first implementation manner, spatial filtering may be performed only on the initial depth map, and spatial depth correction may be performed on the initial depth map, so as to ensure continuity of depth between pixels. The disparity between the previous pixel and the next pixel in the depth map after spatial smoothing is similar, the smaller the color difference between the previous pixel and the next pixel, the higher the similarity of the disparity and the smaller the color difference, the smoother the picture. higher. For example, one-dimensional filtering can be performed in the X-axis and Y-axis directions respectively. The one-dimensional filtering in the X-axis and Y-axis directions is divided into two passes, and the first pass is from the previous pixel on the left to the pixel on the right. For the next pixel, the second pass is from the previous pixel on the right to the next pixel on the left; during the transfer process in the X-axis and Y-axis direc...

Abstract

The present invention provides a depth map processing method and system. The method estimates the depth of the original images captured by a plurality of cameras based on a depth estimation algorithm,obtains an initial depth map, and then performs spatial filtering and / or temporal filtering on the initial depth map based on the depth information obtained from the initial depth map, thereby obtaining a target depth map. The depth map of the invention is processed by spatial filtering and / or temporal filtering, so that the picture of the depth map is smoother, the fluctuation of the picture canbe effectively reduced, the quality of the depth map is well optimized, the depth quality of the three-dimensional image can be improved, and the comfort degree of the human eye when viewing the depth map can be improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a processing method, system and computer-readable storage medium of a depth map. Background technique [0002] At present, one of the most important core technologies for converting a planar 2D image into a stereoscopic 3D image is depth estimation. The currently widely used depth estimation method is based on the binocular depth estimation method, which uses two or more cameras for imaging. Because there is a certain distance between the multiple cameras, the image formed by the same scene through multiple lenses There is a certain difference (that is, parallax), because of the existence of parallax information, it can be used to estimate the general depth information of the scene. [0003] Depth estimation is to calculate the pictures captured by multiple cameras at the same time, and obtain the depth map corresponding to the captured pictures. The depth map ...
