The invention discloses an electric meter box appearance anomaly detection method and device based on image registration and change detection, and the method comprises the steps: carrying out the shooting from the same direction at different times, and obtaining two images of different time phases of the appearance of an electric meter box; inputting the two acquired images into a preset image registration network model, respectively extracting key points and characterization information of the two images, carrying out feature matching on the key points of the two images, calculating a transformation model between the two images according to a key point matching relation, and completing registration between the two images; inputting the registered image into a preset target detection network model, obtaining a specific area containing the electric meter box, and filtering out a background; inputting the two processed appearance images of the electric meter box into a preset change detection network model, and
