To provide an axle number detection device, a toll collection system, an axle number detection method, and a program that make it difficult to erroneously detect the number of axles of tires that touch the ground.SOLUTION: An axle number detection device 25 includes: an image acquisition unit 251 that acquires an image showing a side surface including at least tires of a vehicle; an area identifying unit 252 that identifies a tire area, which is an area where a tire is shown, in the image; a circular detection unit 253 that determines whether the tire area is circular; and a lift-up axle identifying unit 254 that identifies that an axle related to the tire area determined to be circular is lift up.SELECTED DRAWING: Figure 2
【課題】接地するタイヤの車軸数を誤って検出しにくい車軸数検出装置、料金収受システム、車軸数検出方法、及びプログラムを提供する。【解決手段】車軸数検出装置25は、車両の少なくともタイヤが含まれる側面を示す画像を取得する画像取得部251と、画像において、タイヤが写されている領域であるタイヤ領域を特定する領域特定部252と、タイヤ領域が円形か否かを判定する円形判定部253と、円形と判定されたタイヤ領域に関連する車軸がリフトアップされていると特定するリフトアップ軸特定部254と、を備える。【選択図】図2
