Abstract

The invention discloses a novel hybrid optimized image stereo matching method, and belongs to the field of computer vision and image processing. The invention aims to solve the problems that the traditional linear growth algorithm is easily influenced by initial parameter selection, and is poor in reliability and low in efficiency. The method comprises the following steps: determining a parallax region range in a to-be-matched binocular image pair; optimizing the target function by using an optimization algorithm to obtain an optimization result and an optimization variable; substituting the optimization result and the optimization variable into a linear growth algorithm, calculating the parallax energy of the growth area near each root point, and obtaining the parallax energy of the parallax area; filtering the parallax energy of the parallax area through a box type filtering algorithm, and eliminating image edge mismatching; and completing the matching of the binocular image pair tobe matched. The method is suitable for image matching.

Description

technical field [0001] The invention belongs to the fields of computer vision and image processing, and in particular relates to a hybrid optimized image stereo matching method. Background technique [0002] With the rapid development of artificial intelligence, computer vision has gradually become a research hotspot. Computer vision is a subject that studies how to use cameras and computers instead of human eyes to track, identify, analyze, and process targets. Stereo vision is an important branch of it. Stereo matching is to find the corresponding points and points between the images in a given two-dimensional image, and calculate the disparity of the corresponding pixel points in the left and right binocular images, so as to obtain the depth information. It has a wide range of applications in terrain mapping, 3D reconstruction, robotics, remote sensing image analysis, target detection and recognition, etc. [0003] At present, there are many methods to solve the image ...
