Problems solved by technology

[0008] Edge-preserving filtering changes the initial disparity value calculated by stereo matching in consideration of only one of the stereo images, and so there is a problem in that when edge-preserving filtering is applied to each of the stereo images independently, the following phenomenon occurs that requires Disparity values ​​that maintain their left-right consistency do not match each other

Abstract

A device for generating parallax images generates a first initial parallax image and a second initial parallax image by performing stereo matching on a first image and a second image of a stereo image, respectively; performing edge-preserving filtering on the initial disparity images, respectively, to generate a first enhanced disparity image and a second enhanced disparity image; and then by using the reliability factors for the disparity values ​​of each pixel of the first and second initial disparity images and A reliability factor for the disparity value of each pixel of the first and second enhanced disparity images to enhance the disparity value of each pixel of the first and second original disparity images.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0073252 filed with the Korean Intellectual Property Office on May 26, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to a method and apparatus for generating a disparity image, and more particularly, to a method and apparatus for generating a final disparity image by more accurately enhancing an initial disparity obtained by stereo matching. Background technique [0004] Stereo matching is a technique for detecting corresponding points in at least two pages of images. It is possible to use stereo matching techniques to obtain the disparity of corresponding points between at least two views of the image, and to calculate the depth of objects within the image based on the disparity values. Disparity maps can be utilized in various fields such as image-ba...
