Abstract

The invention discloses a method, device and equipment for detecting buckling of strip steel in an annealing furnace and a medium, and belongs to the technical field of metallurgy. The method comprises the following steps: acquiring a surface image of strip steel; performing gradient analysis on the surface image to obtain a gradient value of each pixel point in the surface image; and according to the gradient value, determining the risk grade of buckling of the strip steel. According to the method, the strip steel buckling risk grade can be determined according to the gradient value of each pixel point in the surface image of the strip steel, the strip steel buckling risk grade is determined directly according to the gradient condition of the surface image without depending on the integrity and accuracy of a buckling standard image library, and the accuracy of the detection method is improved.
