Abstract

The invention relates to an artificial intelligence-based evaluation method for hot-rolled steel coil crimp, which performs gray-scale processing on the initial steel coil image to obtain a gray-scale image; processes the gray-scale images respectively to obtain corresponding moiré pattern identification features 1 and 2. Moiré recognition feature 2, and obtain the initial moiré recognition index, when the initial moiré recognition index is greater than the set threshold, the area composed of pixels corresponding to the initial moiré recognition index is the initial moiré area; obtain different camera positions Steel coil image, segment and delete the steel coil image according to the initial moiré area, obtain the feature image, and extract the moiré area, calculate the steel coil curl evaluation value corresponding to the camera position according to the moiré area; according to the total value of the initial steel coil image The area and the obtained steel coil curl evaluation value of each camera position are used to calculate the current coil unwinding degree. That is to say, the present invention realizes the evaluation of steel coil crimp by detecting the moiré pattern, and improves the detection efficiency.

Description

technical field

[0001] The invention relates to the field of steel coil defect detection, in particular to an artificial intelligence-based hot-rolled steel coil crimp evaluation method. Background technique

[0002] At present, the evaluation of the coil image of the steel coil is mainly completed by manual scoring. The defect detection of the coiled steel coil image is realized by the naked eye, and the defective steel coils in the coiled steel coils are found, and the defective steel coils are scored and evaluated. However, there are some subjective factors in the detection based on manual work, and it is easy to cause a greater possibility of wrong evaluation, which requires a certain consumption of human resources. Contents of the invention

[0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a method for evaluating the crimp of hot-rolled steel coils based on artificial intelligence, and the adopted tech...
