Embodiment Construction

[0073] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0074] The present invention proposes a binocular vision measurement and positioning device in a narrow space. The device includes a binocular vision platform and a vision measurement terminal. There are two groups of measurement terminals, each group of visual measurement terminals is composed of cameras, lasers and telescopic calibration plates, and the two groups of visual measurement terminals are respectively axially symmetrically installed on the two motion rotation axes of the binocular vision platform. The visual measurement terminal is structurally designed according to the characteristics of the narrow space and the principle of visual measurement positioning, and then the visual measurement terminal is installed on the two rotational axes of the four-degree-of-freedom platform.

[0075] The structural diagram of the existing visual platform based on the bi...

Abstract

The invention provides a narrow space binocular vision measuring and positioning device and method, which are suitable for related technical fields such as narrow space assembling and fault analysis. The vision measuring and positioning device comprises a binocular vision platform and two groups of vision measuring terminals, wherein a vision platform based on a space four-degree-of-freedom binocular camera is selected as the binocular vision platform; each group of vision measuring terminal comprises a camera, a laser and a telescopic calibration plate; and the two groups of vision measuring terminals are axially and symmetrically arranged on two movement rotating shafts of the binocular vision platform. The invention provides a narrow space binocular vision measuring and positioning device and method; the vision measuring terminals are arranged on the rotating shafts of the four-degree-of-freedom platform; the platform freely moves; the measuring terminals are flexibly installed, and can acquire images in the narrow space; the method can be applied to special environment with a bad imaging environment, and can be applied to object measuring in the narrow space; and the method is an effective vision measuring method.

Description

technical field [0001] The invention relates to a binocular vision accurate measurement and positioning device and method, which is particularly suitable for narrow space target measurement and positioning, and can be used for narrow space assembly, fault analysis and other related technical fields. Background technique [0002] Visual measurement and positioning technology uses images as the carrier of information and is closely integrated with computer technology. It has the characteristics of non-contact, all-round rapid measurement and positioning, and high precision. It has been widely used in various measurement tasks. Binocular vision measurement and positioning is a stereo vision system composed of two cameras, simulating the way of human vision, according to the principle of triangulation, using the parallax of corresponding points to transform, match and reconstruct the obtained image, and the field of view can be reversed. Stereo information of objects within rang...
