Abstract

The invention provides a method and device for optimizing depth information. The method includes: dividing one of the left image and the right image into a plurality of related blocks to obtain at least one block distribution map. Obtain the depth map to be repaired, and divide the depth map to be repaired into multiple depth planes according to multiple main depth values ​​and camera parameters, wherein the depth map to be repaired records these main depth values ​​and has multiple holes. A plurality of optimized depth values ​​are respectively generated for holes in each depth plane by using the block distribution map, and these optimized depth values ​​are filled into each depth plane to obtain 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 optimizing depth information. Background technique [0002] With the vigorous development of image processing technology, stereo vision technology (Stereo Vision) is 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 aberratio...
