Multi-view three-dimensional reconstruction method based on binocular stereoscopic vision system

Abstract

The invention discloses a multi-view three-dimensional reconstruction method based on binocular stereoscopic vision system. The multi-view three-dimensional reconstruction method comprises the following steps of: designing a binocular stereoscopic vision system according to the scale of a reconstructed object, calibrating the camera of the binocular stereoscopic vision system in advance, and producing a lookup table of the binocular stereoscopic vision system for restoring three-dimensional information; acquiring the video information of the reconstructed object by the binocular camera, performing homographic transformation on the video information acquired by the right camera, and stereoscopically matching the homographically transformed video information to video image of the left camera to obtain a disparity map of the reconstructed object, restoring the three-dimensional information corresponding to the reconstructed object; obtaining the three-dimensional point cloud information of the reconstructed object in different view angles, transforming the three-dimensional point cloud into the same coordinate system in virtue of point cloud preprocessing, rough registration and fine registration so as to complete the three-dimensional reconstruction of the reconstructed object. The multi-view three-dimensional reconstruction method greatly reduces the cost of three-dimensional reconstruction equipment, is simple and effective in process, and is high in engineering application value.

Description

technical field [0001] The invention relates to the technical field of multi-lens machine vision, in particular to a multi-view three-dimensional reconstruction method based on a binocular stereo vision system. Background technique [0002] Three-dimensional reconstruction is to establish a mathematical model suitable for computer representation and processing of three-dimensional objects through digital means. Two-dimensional information has been applied in many fields, but with the requirements of industrial production, the two-dimensional information of objects can no longer meet people's requirements. 3D reconstruction technology can quickly and accurately digitally represent 3D objects. As a result, it has been widely used in many fields such as industrial measurement, 3D printing, digitalization of cultural relics, human-computer interaction, etc., and its research value has become increasingly prominent. [0003] There are usually two methods for 3D data acquisition...

Problems solved by technology

Two-dimensional information has been applied in many fields, but with the requirements of industrial production, the two-dimensional information of objects can no longer meet people's requirements

[0004] At present, the existing 3D information acquisition equipment is expensive, and the 3D reconstruction operation is relatively complicated

The 3D reconstruction based on the binocular stereo vision system can greatly reduce the cost of 3D information acquisition equipment under the same reconstruction effect. At present, the 3D reconstruction based on the binocular stereo vision system has few market applications and has high research value, application value and market value.
