Electric arc furnace smelting state judgment method and device based on artificial intelligence

The invention relates to the technical field of artificial intelligence, and concretely relates to an electric arc furnace smelting state judgment method and device based on artificial intelligence. The method comprises the following steps: obtaining an image of the electric-arc furnace smelting process; carrying out gray compensation on the image; setting a continuous frame image window and a gray threshold, and judging whether the smelting process enters an oxidation period from a melting period or not according to the maximum frame number continuously exceeding the gray threshold in the window, the total frame number exceeding the threshold and a probability value obtained by the size of the window; and after entering the oxidation period, segmenting the obtained target area image of the smoke area through an adaptive double-threshold segmentation algorithm, traversing each pixel of the target image, obtaining pixel areas of a pure white area and a pure black area, and judging whether the electric arc furn
