To provide an anomaly detection device capable of detecting an anomaly that would prevent normal travel of a vehicle.SOLUTION: An anomaly detection device includes: an identifying unit 31 configured to identify a path region in an image representing surroundings of a vehicle 10, the path region representing a lane on which the vehicle 10 is traveling; an extraction unit 32 configured to extract a feature quantity indicating the condition of a road surface regarding the path region from the image by inputting the path region in the image into a feature extractor that has been trained to extract the feature quantity; and a detection unit 33 configured to detect an abnormal condition in which the vehicle 10 cannot travel normally on the lane, when the feature quantity is outside a normal range that represents a tolerable range in which the vehicle 10 can travel normally.SELECTED DRAWING: Figure 3
【課題】車両の通常走行を妨げる異常を検知することが可能な異常検知装置を提供する。【解決手段】異常検知装置は、車両10の周囲を表す画像における、車両10が走行している自車線を表す走路領域を特定する特定部31と、画像から、路面の状況を表す特徴量を抽出するよう予め学習された特徴抽出器に画像の走路領域を入力することで、走路領域についてのその特徴量を抽出する抽出部32と、車両10が通常走行可能な許容範囲を表す正常範囲に特徴量が含まれない場合に、自車線において車両10が通常走行可能でない異常な状況を検知する検知部33とを有する。【選択図】図3
