To provide an image recognition device and an image recognition method capable of appropriately recognizing a road traffic sign.SOLUTION: A control device 20 includes: an image information obtaining unit 21 that obtains image information obtained by imaging a running road through which a vehicle runs; a sign recognizing unit 22 that recognizes a road traffic sign on the basis of the image information; a traffic lane recognizing unit 23 that recognizes the traffic lane of the running road on the basis of the image information; a storing unit 24 that stores traffic lane information relating to the traffic lane recognized by the traffic lane recognizing unit in a time-series manner; and a determining unit 25 that determines whether or not the road traffic sign recognized by the sign recognizing unit corresponds to the local traffic lane. The determining unit 25 selects the traffic lane to which the road traffic sign is most appropriate among the traffic lanes recognized during a preset time period on the basis of the traffic lane information stored in the time-series manner so as to determine whether or not the road traffic sign corresponds to the local traffic lane.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】制御装置20は、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21と、画像情報に基づいて、道路標識を認識する標識認識部22と、画像情報に基づいて、走行路の車線を認識する車線認識部23と、車線認識部により認識された車線に係る車線情報を時系列で記憶する記憶部24と、標識認識部により認識された道路標識が、自車線に対応するか否かを判定する判定部25と、を備える。判定部25は、時系列で記憶された車線情報に基づいて、予め決められた期間に認識された車線のうち、道路標識が最もふさわしい車線を選択することにより、道路標識が自車線に対応するか否かを判定する。【選択図】 図2
