To provide a vehicle type discrimination device capable of restricting an erroneous vehicle type discrimination result from being used in toll collection processing when there is a possibility of erroneous recognition of a license plate information.SOLUTION: A vehicle type discrimination device includes: a license plate reader for reading license plate information of a vehicle; a vehicle width measurement section for measuring a vehicle width of the vehicle; a determination section for determining that there is a possibility of erroneous recognition of the license plate information when the vehicle width measured by the vehicle width measurement section is out of an effective range; and a vehicle type discrimination section for performing first processing to discriminate the vehicle type of the vehicle based on the vehicle width and the license plate information when it is determined that there is no possibility of the erroneous recognition, and performing second processing to make the vehicle type of the vehicle unclear or to narrow down vehicle type candidates of the vehicle when it is determined that there is the possibility of the erroneous recognition.SELECTED DRAWING: Figure 2
【課題】ナンバープレート情報の誤認識の可能性がある場合に、誤った車種判別結果が料金収受処理で用いられることを抑制可能な車種判別装置を提供する。【解決手段】車種判別装置は、車両のナンバープレート情報を読み取るナンバープレート読取装置と、前記車両の車幅を計測する車幅計測部と、前記車幅計測部が計測した前記車幅が有効範囲外であった場合、前記ナンバープレート情報の誤認識の可能性があると判定する判定部と、誤認識の可能性がないと判定された場合に、前記車幅と前記ナンバープレート情報とに基づいて前記車両の車種を判別する第1処理を実行し、誤認識の可能性があると判定された場合に、前記車両の車種を不明とする、又は前記車両の車種の候補を絞り込む第2処理を実行する車種判別部と、を備える。【選択図】図2
