description The invention discloses a mask appearance detection system, which comprises the following steps: acquiring mask images shot by a camera, selecting a mask image to be detected in the mask images when judging that the mask images contain complete masks, correcting the mask image to be detected, and positioning the coordinates of the masks. Performing region segmentation according to the coordinates of the mask to obtain a to-be-detected region of the mask, extracting ear bands belonging to the to-be-detected region, performing primary segmentation on an image of the ear bands by using an Otsu method to obtain a target image, and obtaining and storing the segmented target image. The target image comprises a plurality of isolated points and a trunk contour is clear and is not damaged, and the isolated points are removed by using shape template matching of a specified area so as to measure the diameter of the trunk image to obtain a mask appearance detection result. The ear band image is accurately extracted from
