To provide an axle number measurement device, etc. which can exactly measure the number of axles of grounded tires even under the environment in which noise in an image increases, for example, at night.SOLUTION: An axile number measurement device 30 for measuring the number of axles of a vehicle 40 traveling on a road 50 comprises: a first communication unit 31 which acquires a pickup image P1 including tires of the vehicle 40; a detection unit 33 which detects the tires from the pickup image P1; a second communication unit 32 which acquires a plurality of second distances from the vehicle 40 to the road 50; and a measurement unit 34 which measures the number of axles supporting the tires in contact with the road 50 on the basis of the pickup image P1 and the plurality of second distances. The measurement unit 34 determines whether or not the tires is in contact with the road 50 on the basis of a second distance directly under the tires detected by the detection unit 33.SELECTED DRAWING: Figure 2
【課題】夜間など画像におけるノイズが増加する環境下においても、接地しているタイヤの車軸数を正確に計測することができる車軸数計測装置等を提供する。【解決手段】車軸数計測装置30は、道路50を走行する車両40の車軸数を計測する車軸数計測装置であって、車両40のタイヤを含む撮像画像P1を取得する第1通信部31と、撮像画像P1からタイヤを検出する検出部33と、車両40の道路50までの複数の第2距離を取得する第2通信部32と、撮像画像P1と複数の第2距離とに基づいて、道路50と接触しているタイヤを支持する車軸数を計測する計測部34とを備え、計測部34は、検出部33により検出されたタイヤの直下の第2距離に基づいて、タイヤが道路50と接触しているか否かの判定を行う。【選択図】図2
