Embodiment Construction

[0026] As shown in FIG. 1 , the strip steel surface defect testing platform based on machine vision of the present invention consists of three parts: a strip steel simulation motion platform 11 , a linear motion control device 12 , a camera and a light source adjustment device 13 . The strip steel simulation motion platform 11 effectively absorbs the strip steel samples with defects and can move smoothly in a straight line; the linear motion control device 12 controls the platform 11 to simulate a strip steel production line to perform uniform and accelerated motion; the camera and The light source adjustment device 13 realizes the multi-angle adjustment of the high-speed linear array industrial camera and the light source, and collects moving images of steel strip defect samples in real time.

[0027] The structure of the machine vision-based strip surface defect testing platform of the present invention is shown in FIG. 2 .

Abstract

The strip steel surface defect detecting platform based on machine sight includes one strip steel motion simulating platform comprising bench, straight guide rail, slide carriage moving on the guide rail and electromagnetic attractor array; one rectilinear motion controlling device including frequency variable servo control system and ball screw to drive the slide carriage; and one CCD camera and light source regulator including support capable of moving longitudinally, CCD camera regulating support and light source regulating support. The present invention can simulate the motion of strip steel in the production line, and suitable for on-line detection.

Description

technical field [0001] The invention relates to a machine vision-based strip steel surface defect testing platform, which simulates the linear movement of the strip steel, and obtains the best image of the strip steel defect through a camera and light source cooperation test. The invention also relates to a method for detecting the surface defect of the strip by using the surface defect testing platform of the strip. Background technique [0002] Machine Vision (Machine Vision) is a rapidly developing new technology. In modern large-scale production, visual inspection is often an indispensable link, and machine vision systems can replace artificial vision for various occasions of detection and identification, especially quality inspection in high-speed, large-volume, continuous automated production, Work that is difficult to do manually, such as object recognition and dimension measurement. Compared with artificial vision, the biggest advantage of machine vision is accurac...
