Problems solved by technology

The depth of the tree is determined by using interpolation coefficients calculated independently of objects positioned in the image (e.g. obstacles), so the matching accuracy may be lower
In addition, when the quadtree-based stereo matching algorithm is applied to utilize stereo images to calculate the distance to objects, the matching accuracy may be lower

Abstract

The present invention relates to an apparatus, method and computer-readable medium for correcting interpolation coefficients for stereo matching. Wherein the means for correcting an interpolation coefficient for stereo matching includes: an interpolation coefficient generating section configured to generate an interpolation coefficient λ; a correction value calculating section configured to calculate a parameter and a weight value based on a position of an object in an image; and An interpolation coefficient correcting section configured to correct the generated interpolation coefficient by multiplying the calculated parameter and the calculated weight value by the generated interpolation coefficient.

Description

technical field [0001] The present invention relates to an apparatus for correcting interpolation coefficients for stereo matching, and more particularly to a technique for correcting interpolation coefficients determined in a quad-tree-based stereo matching algorithm The depth of the tree (depth). Background technique [0002] Usually, the quadtree-based stereo matching algorithm calculates the interpolation coefficient (λ) by matching the detection cost function, and determines the depth (ie structure) of the tree based on the interpolation coefficient. By using interpolation coefficients calculated independently of objects positioned in the image (eg obstacles) to determine the depth of the tree, the accuracy of the matching may therefore be relatively low. In addition, when the quadtree-based stereo matching algorithm is applied to utilize stereo images to calculate the distance to objects, the matching accuracy may be lower. Therefore, there is a need for a solution t...
