Cold rolling process steel bending detection and analysis method based on artificial intelligence

Abstract

The invention discloses a cold rolling process steel bending detection and analysis method based on artificial intelligence. The problem that in the prior art, a cold bed steel bending phenomenon needs to be detected intelligently is solved. The method comprises the following steps: deploying an RGB camera at the tail end of a cooling bed, converting an acquired image into a grey-scale map, and filtering interference noise of the image through bilateral filtering; carrying out canny edge detection on the steel image, and converting the steel image into a steel profile diagram only containing edge information; carrying out Hough straight line detection on the contour map, and screening and filtering straight lines; analyzing the residual bending contour image information, constructing a steel bending defect degree index analysis model, and calculating a steel bending defect degree index; and setting a corresponding steel bending state analysis model, obtaining the bending direction and shape position information of the steel, and carrying out optimization adjustment. The technology ensures the quality of steel products in the subsequent operation process and reduces the steel bending defect in the subsequent steel cold rolling process.

Description

technical field [0001] The invention relates to the field of artificial intelligence computer vision processing, in particular to an artificial intelligence-based method for detecting and analyzing steel bending during cold rolling. Background technique [0002] Cooling bed is one of the indispensable auxiliary equipment in small and medium-sized steel workshops. Its function is to cut the steel into multiple lengths by flying shears after rolling in the rolling mill, transport and unload it to the rack of the cooling bed for cooling, so that the temperature will drop from 900 ° C to 100 ~ 300 ° C, and then the material will be unloaded by the cooling bed The device collects them into groups and sends them to the output roller table, and then the output roller table sends them to the cold shears to cut them into finished products. There are many reasons for the bending of steel in the cooling bed. The input roller table of the cooling bed does not rotate, which cannot make ...
