To make it possible to associate one vehicle with another between two points while suppressing costs required for construction and operation of a system.SOLUTION: A first point image produced by imaging wheels of a vehicle 100 at a first point and a second point image produced by imaging the wheels of the vehicle 100 at a second point different from the first point are inputted to an identification device 1. A feature quantity extraction unit 11a extracts a feature quantity of the wheels by processing each of the first point image and the second point image. An association unit 11b associates the vehicle 100, the wheels of which are shown in the first point image, with the vehicle 100, the wheels of which are shown in the second point image, by collating the feature quantity of the wheels, which is extracted by the feature quantity extraction unit 11a, with the other one.SELECTED DRAWING: Figure 4

    【課題】システムの構築、および運用にかかるコストを抑え、2地点間で車両を対応付けることができる。【解決手段】同定装置1には、第1の地点で車両100の車輪を撮像した第1地点画像、および第1の地点とは異なる第2の地点で車両100の車輪を撮像した第2地点画像が入力される。特徴量抽出部11aは、第1地点画像、および第2地点画像を処理して車輪の特徴量を抽出する。対応付部11bは、特徴量抽出部11aが抽出した車輪の特徴量の照合により、第1地点画像に車輪が撮像されている車両100と、第2地点画像に車輪が撮像されている車両100とを対応付ける。【選択図】図4
