Abstract

The invention relates to a hot rolled steel coil curl evaluation method based on artificial intelligence. The method comprises the following steps: performing graying processing on an initial steel coil image to obtain a gray image; respectively processing the gray level image to obtain a corresponding moire pattern recognition feature I and a moire pattern recognition feature II, obtaining an initial moire pattern recognition index, and when the initial moire pattern recognition index is greater than a set threshold value, taking a region formed by pixel points corresponding to the initial moire pattern recognition index as an initial moire pattern region; acquiring steel coil images at different camera positions, segmenting and deleting the steel coil images according to the initial moire region to obtain a feature image, extracting the moire region, and calculating a steel coil curling evaluation value corresponding to the camera position according to the moire region; and calculating the coil loosening degree of the current steel coil according to the total area of the initial steel coil image and the obtained steel coil curling evaluation value of each camera position. According to the method, the moire is detected, so that the curl of the steel coil is evaluated, and the detection efficiency is improved.

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...
