Automatic leveling device of binocular stereo camera, and leveling control system and control method thereof

Abstract

The invention discloses an automatic leveling device of a binocular stereo camera, and a leveling control system and control method thereof. The device comprises a leveling target, a control system, aclamping system and movement adjustment systems; the control system controls the action of the clamping system and / or the movement adjustment systems according to an image position signal of the leveling target shot by the binocular stereo camera; the clamping system clamps or releases two circuit boards according to the instruction of the control system; and two movement adjustment systems abutagainst the two circuit boards in a one-to-one correspondence manner and respectively drive the circuit boards on the corresponding sides to reciprocate to preset displacements on the vertical direction according to the instruction of the control system. The automatic leveling device of the binocular stereo camera can realize automatic leveling without the manual leveling of the worker, thereby simplifying the camera leveling operation process and reducing the camera leveling workload.

Description

technical field [0001] The invention relates to the technical field of stereo imaging, in particular to an automatic leveling device for a binocular stereo camera. The invention also relates to a leveling control system based on the automatic leveling device, and a control method based on the leveling control system. Background technique [0002] Binocular stereo vision is a technology that captures the position information of objects by designing and imitating human vision. It is widely used in reverse engineering, test and measurement, visual navigation and other fields. In principle, binocular stereo vision uses two imaging devices to obtain two images of the measured object from different positions, calculates the internal parameters and external parameters of the camera, and calculates the position deviation between the corresponding pixels of the image (called as "parallax disparity") to obtain the distance between the object and the imaging device, thereby obtaining ...

AI Technical Summary

Problems solved by technology

However, the manual leveling process of the binocular camera is cumbersome, resulting in low leveling efficiency, which seriously affects the output of the binocular camera; moreover, manual leveling largely relies on the experience of the staff, resulting in poor leveling accuracy , the accuracy consistency is difficult to guarantee
