Novel binocular stereo vision measuring device

Abstract

The invention relates to a novel binocular stereoscopic vision measuring device, which comprises two omnibearing vision sensors provided with the same imaging parameters, a connecting unit and a microprocessor which is used for performing three-dimensional stereoscopic vision reconstruction on images of the two omnibearing vision sensors, wherein the omnibearing vision sensors comprise hyperbolic mirror surfaces, upper covers, stand bars, transparent glass surfaces, supplementary lens frames and image units; the upper covers are arranged on the hyperbolic mirror surfaces; the stand bars are round platforms with thick upper parts and thin lower parts; upper ends of the stand bars are arranged inside small holes in bottom centers of the hyperbolic mirror surfaces, and lower ends of the stand bars are arranged inside mounting holes in the centers of the transparent glass surfaces which are embedded into the supplementary lens frames; the stand bars are perpendicular to the transparent glass surfaces; and the image units are positioned inside the supplementary lens frames. The novel binocular stereoscopic vision measuring device simplifies the complexity of calculation of stereo matching and so on, saves the operation of camera calibration, is convenient to perform feature extraction, is easy to realize stereo image matching, and finally achieves the aim of high-efficiency, real-time and accurate stereoscopic vision measurement.

Description

technical field

[0001] The invention belongs to the application of optical technology and computer vision technology in stereo vision measurement. Background technique

[0002] Binocular stereo vision 3D measurement and stereo reconstruction technology based on computer vision is an emerging application technology with great development potential and practical value, which can be widely used in industrial inspection, geographical survey, medical cosmetic surgery, orthopedic orthopedics, Reproduction of cultural relics, criminal investigation and evidence collection, security identification, robot vision, rapid prototyping of molds, gifts, virtual reality, animated films, games and many other application fields.

[0003] The basic principle of stereo vision is to observe the same scene from two viewpoints to obtain perceptual images under different viewing angles, and calculate the position deviation between image pixels, that is, parallax, through the principle of triangulat...
