Abstract

The invention provides a method and device for generating depth information, and the method includes the following steps. A master depth map associated with one of the left image or the right image and corresponding to a plurality of first pixels is acquired. According to the pixel information, the left image or the right image associated with the main depth map is divided into a plurality of related blocks, so as to obtain a block distribution map including the related blocks. Multiple invalid depth values ​​that do not meet the confidence condition are removed from the main depth map using the block distribution map, resulting in a depth map to be repaired that includes multiple holes. The block distribution map is used to generate a plurality of optimized depth values ​​for the holes in the depth map to be repaired, and the optimized depth values ​​are filled into the depth map to be repaired to generate an optimized depth map.

Description

technical field [0001] The present invention relates to a method and device for processing images, and in particular to a method and device for generating depth information. Background technique [0002] With the vigorous development of image processing technology, stereo vision technology (Stereo Vision) has been gradually and widely used in various fields. Broadly speaking, stereo vision can include two stages. The early stage includes the use of depth cameras, stereo cameras, or related 3D stereo image algorithms to generate depth information, and the second stage is to use depth information to generate images from different perspectives. It can be seen that, in order to generate a stereoscopic image with better visual experience, accurate depth information is very important. [0003] For a stereoscopic imaging system with dual lenses, the dual lenses of the stereoscopic imaging system can capture images from different angles in the same area, and by combining the aberra...
