Abstract
A tire configuration judging device according to the present invention comprises a light projecting (emitting) device, a photographing device, and a control device. The light projecting device irradiates slit light onto a bead portion of a tire. The photographing device photographs a slit image which is formed on the tire. The control device forms an image to be judged which represents an external configuration of the bead portion of the tire, by applying a 2-D coordinate conversion to image data for the slit image which is photographed by the photographing device. The image to be judged and a predetermined reference image are compared to each other by a comparing device such that quality of the tire is judged, and the tire is classified as a normal tire or an abnormal tire according to results of comparison.
