Multi-freedom-degree adjustable image acquisition device

Abstract

The invention relates to a multi-freedom-degree adjustable image acquisition device. Five sets of same moving execution mechanisms are distributed on a supporting platform of the multi-freedom-degree adjustable image acquisition device; the center line of each moving execution mechanism passes through the center point of the supporting platform, and a plurality of included angles are formed by the center lines and the horizontal direction; each moving execution mechanism consists of guide rails, sliding blocks, a moving platform, a screw rod and a servo motor; each rotary execution mechanism consists of a slewing drive, a posture adjusting platform and a servo motor. According to the multi-freedom-degree adjustable image acquisition device disclosed by the invention, the multi-freedom-degree execution mechanisms are applied to the field of vision acquisition, so that the multi-freedom-degree adjustable image acquisition device of which the intelligent degree is high is formed; under the effect of the moving execution mechanisms and the rotary execution mechanisms, the position and the posture of each digital camera and the position and the posture of each laser light source can be independently adjusted according to the shape of a measured article and vehicle disturbance, so that a plurality of technical difficult problems caused during applying a conventional machine vision technology in a highway are solved.

Description

technical field [0001] The invention belongs to the technical field of image acquisition, and relates to vehicle-mounted visual inspection equipment for highway building health inspection, in particular to an intelligent multi-degree-of-freedom adjustable image acquisition device. Background technique [0002] Machine vision is to use machines instead of human eyes for measurement and judgment. The most basic advantage is that it can improve the flexibility and automation of production. It is often used in dangerous working environments that are not suitable for manual work or where artificial vision is difficult to meet the requirements. Using machine vision to replace artificial vision, the use of machine vision inspection methods can greatly improve production efficiency and automation. [0003] When machine vision is applied to the health inspection of highway buildings, the image acquisition system is installed on a moving vehicle to form a vehicle-mounted rapid acquisi...

AI Technical Summary

Problems solved by technology

On the one hand, it reduces the intelligence of the system; on the other hand, vehicle bumps affect the focusing device of the digital camera, which disturbs the image acquisition

[0004] To sum up, the existing technical conditions limit the application of machine vision technology in highway intelligent detection. Adjust the position and attitude of the image acquisition device, resulting in poor image quality, affecting subsequent image processing and feature recognition
