1. A method for detecting wheel fastener looseness, the method comprising the steps of:
causing an information device including a capturing function to use the capturing function to capture an image of a disc wheel to which a plurality of wheel fasteners are fastened; and
causing the information device to inspect whether any one of the wheel fasteners appearing in the captured image is loose by comparing the captured image with a reference image in consideration of a reference point of the disc wheel appearing in the captured image.
