To provide a tire specification discrimination device and a tire specification discrimination method that can easily discriminate tire specifications in a short time.SOLUTION: A tire specification discrimination device 1 includes: photographing means 10 for photographing a side surface of, for example, a tire M1; cutout means 20 for cutting out, as a discrimination image, an image of a region enclosed by a first circle corresponding to an inner side of the outer circumference of a wheel of the tire M1 and a second circle whose radius is larger than the outer circumference of the wheel and which includes the first circle inside, in a captured image obtained by the photographing means 10; and discrimination means 30 for discriminating specifications of the tire M1 based on the discrimination image cut out by the cutout means 20.SELECTED DRAWING: Figure 1
【課題】簡単に短時間で判別することができるタイヤ仕様判別装置及びタイヤ仕様判別方法を提供する。【解決手段】タイヤ仕様判別装置1は、例えば、タイヤM1の側面を撮影する撮影手段10と、撮影手段10により得られた撮影画像において、タイヤM1のホイールの外周の内側に対応する第1円と、ホイールの外周よりも半径が大きくかつ第1円を内側に含む第2円とにより囲まれた領域の画像を判別画像として切り出す切出手段20と、切出手段20により切り出した判別画像に基づき、タイヤM1の仕様を判別する判別手段30とを備えている。【選択図】図1
