To provide an image recognition device and an image recognition method that can appropriately recognize a road sign.SOLUTION: An image recognition device 33 comprises: an image information acquisition unit 41 that acquires image information obtained by capturing an image of a traveling route on which the own vehicle is traveling; a sign recognition unit 42 that recognizes a road sign based on the image information; a sign specifying unit 45 that specifies a road sign around the own vehicle by referring to map information generated based on travel track information of a vehicle; a collation unit 46 that collates the road sign recognized by the sign recognition unit 42 with the road sign based on the map information, in which when these road signs match with each other, the collation unit defines the matched road sign as a collation result, whereas the collation unit selects one of the road signs as a collation result, or selects neither road sign when these road signs do not match; and an output unit 47 that outputs the collation result.SELECTED DRAWING: Figure 2

    【課題】道路標識を適切に認識できる画像認識装置、及び画像認識方法を提供すること。【解決手段】画像認識装置33は、自車両が走行する走行路を撮像した画像情報を取得する画像情報取得部41と、前記画像情報に基づいて、道路標識を認識する標識認識部42と、車両の走行軌跡情報に基づいて生成された地図情報を参照して、自車両周辺における道路標識を特定する標識特定部45と、前記標識認識部42により認識された道路標識と、前記地図情報に基づく道路標識とを照合し、一致した場合には、一致した道路標識を照合結果とする一方、一致しなかった場合には、いずれか一方を照合結果として選択する、若しくはいずれも選択しない照合部46と、前記照合結果を出力する出力部47と、を備えた。【選択図】 図2
