Steel coil defect identification method and device

The invention provides a steel coil defect recognition method and device and electronic equipment, and the method comprises the steps: carrying out the semantic segmentation of a target image through a steel coil defect mask model, obtaining a recognition result of a steel coil defect region, and enabling the target image to be an image comprising at least a part of the end surface of a steel coil; based on the identification result of the steel coil defect area, carrying out contour extraction on the steel coil defect area in the target image to obtain the contour of at least one steel coil defect; carrying out bounding box calculation on the contour of each steel coil defect to obtain the bounding box size of each steel coil defect; determining whether a defect alarm signal is generated or not according to a comparison result of the maximum bounding box size in the bounding box sizes of the at least one steel coil defect and a preset alarm size; and superposing the contour of at least one steel coil defect
