Abstract

The invention discloses a method and system for detecting a specific plane in stereoscopic vision. The method includes: generating an inverse transmission transformation map according to at least one of a disparity map and a grayscale image; and generating a width-distance based on the disparity map. map; and detecting the specific plane based on matching of the inverse transformation map and the width-distance map. By detecting the specific plane based on the matching of the inverse transmission map (IPM map) and the width-distance map (RWD map) generated from the disparity map and / or grayscale map, the specific plane can be detected more accurately specific plane.

Description

technical field [0001] The present invention relates to a method and system for detecting a specific plane, and more particularly, to a detection technology for detecting a specific plane such as a road surface in a stereo vision system. Background technique [0002] Nowadays, with the continuous deepening and development of image processing technology, people can no longer be satisfied with two-dimensional images that only reflect the plane vision of objects. Stereo vision, such as 3D / three-dimensional technology, has been researched and produced many applications. [0003] There is parallax when the left and right eyes of people observe objects, and this discovery has laid the theoretical basis for binocular stereo vision. Binocular stereo vision is to use two cameras in different positions (so-called binocular cameras) or one camera to shoot the same scene after moving or rotating, and match the corresponding image points through various algorithms, so as to calculate th...
