Method and device for removing background of image and electronic equipment

The invention discloses an image background removing method and device and electronic equipment. The method comprises the steps: calling a template image from a pre-established image template library based on an end face image of a hot rolled steel coil, taking the template image as a current template image, and executing the following matching recognition steps: carrying out the superposition processing of the current template image and the end face image, the image template library stores a plurality of template images obtained on the basis of the sample end face image of the hot rolled steel coil, each template image comprises an image removal area, a part of the image, overlapped with the image removal area of the current template image, in the end face image is removed, and the remaining image is reserved in the overlapped image; and inputting the superimposed image into a pre-trained matching model, determining whether the current template image is matched with the end face image, If so, taking the supe
