To provide a technique capable of accurately identifying a vehicle between points by processing frame images of a license plate of the vehicle which are captured at three or more points.SOLUTION: A vehicle tracking device 1 stores in a recognition result storage unit 13 a recognition result of recognizing a registration number inscribed on a license plate of a vehicle which passes a first point and a second point on a traveling passage and a recognition result of recognizing a series of designation numbers as a part of a registration symbol inscribed on the license plate of the vehicle passing an intermediate point which is positioned between the first point and the second point. An identification unit 11a uses the recognition result at each of the points to identify the vehicle between the points. The recognition result at the first point and the recognition result at the second point include time of passage of the vehicle.SELECTED DRAWING: Figure 4

    【課題】3つ以上の地点で撮像した車両のナンバープレートのフレーム画像を処理し、地点間での車両の同定が精度よく行える技術を提供する。【解決手段】車両追跡装置1は、走行路の第1地点および第2地点を通過した車両のナンバープレートに表記されている登録記号を認識した認識結果及び第1地点と第2地点との間に位置する中間地点を通過した車両のナンバープレートに表記されている登録記号の一部である一連指定番号を認識した認識結果を認識結果記憶部13に記憶する。同定部11aが、各地点の認識結果を用いて、地点間で車両を同定する。第1地点の認識結果および第2地点の認識結果には、車両の通過時刻が含まれている。【選択図】図4
