Abstract

The invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based hot-rolled strip steel scabbing defect detection method and system. The method comprises the following steps: acquiring an RGB image of hot-rolled strip steel and converting the RGB image into a grey-scale map; filtering the grey-scale map, carrying out straight line detection and edge detection on the processed grey-scale map, carrying out overlap ratio judgment on an obtained straight line and a first edge line, and filtering out an isolated straight line and an error edge line to obtain a second edge line; performing intersection point screening on the second edge lines, so that the second edge lines capable of obtaining the complete contour through intersection points and/or the second edge lines forming the complete contour with the gray-scale map boundary are/is reserved and recorded as third edge lines, and a scabbing area is determined; and judging whether the edge of the scabbing area has a warping part or not according to whether a shadow exists on the third edge line of the scabbing area or not, and obtaining the warping degree of the scabbing area. According to the embodiment of the invention, noise interference can be greatly eliminated, and the scarring defect of the strip steel can be accurately and quickly detected.

Description

technical field [0001] The invention relates to the technical field of artificial intelligence, in particular to an artificial intelligence-based method and system for detecting scab defects in hot-rolled strip steel. Background technique [0002] In the metallurgical industry, hot-rolled strip scarring defects are also called heavy skin defects, which are generally distributed on the surface of the strip steel in the form of irregular tongue-shaped, scale-shaped, strip-shaped or M-shaped metal flakes. There are two forms of this defect, one is connected to the strip steel substrate; the other is not connected to the strip steel substrate, but is still bonded to the surface, easy to fall off, and will form pits after falling off, making the surface of the substrate It is no longer smooth and affects the use. The cause of scarring defects is mainly due to scarring and burrs on the surface of the slab, which remain on the surface of the strip after rolling or residues left af...
