Abstract

The invention discloses a stereo matching three-dimensional reconstruction method based on dynamic programming. A system according to the method is composed of two video cameras. The stereo matching three-dimensional reconstruction method comprises the following steps of (1), adjusting the positions of the two video cameras so that imaging planes of the two video cameras are parallel as possible; (2), performing calibration on a three-dimensional measuring system, obtaining inner parameters and outer parameters of the two video cameras, and obtaining a correspondence between pixel coordinates on an image and a world coordinate system; (3), performing epipolar line rectification and image conversion; (4), obtaining a parallax graph by means of a stereo matching algorithm based on dynamic programming; (5), performing parallax correction; and (6), obtaining a three-dimensional point cloud according to a video camera calibration parameter and the parallax graph through a spatial intersection method. The stereo matching three-dimensional reconstruction method has advantages of high parallax graph precision and high real-time performance. Furthermore the three-dimensional point cloud of the image can be accurately, quickly and automatically reconstructed.

Description

technical field [0001] The invention belongs to the technical field of binocular stereo vision and relates to the problem of image processing based on stereo matching. Background technique [0002] Binocular stereo vision technology is a passive three-dimensional measurement method, which is flexible in implementation, low in environmental requirements, and friendly to human-computer interaction. It is a relatively popular technology in three-dimensional reconstruction algorithms. Binocular stereo vision aims to simulate the mechanism of human binocular recognition of three-dimensional information of the scene, obtain two-dimensional images of the scene from two angles, and then reconstruct the three-dimensional model according to the matching relationship between the established images, mainly including camera calibration, image pair matching, three-dimensional Information restoration and other main processes. The process of establishing the corresponding relationship betw...
