To provide an abnormality detection device capable of improving detection accuracy of an abnormality disturbing normal traveling of a vehicle.SOLUTION: An abnormality detection device comprises: an extraction section 31 that extracts feature amount by inputting an image showing the surroundings of a vehicle 10 to a feature extractor preliminarily trained so as to extract a feature amount showing a state of a road surface; a detection section 32 that detects an abnormal state in which the vehicle 10 cannot normally travel when the feature amount is not included in a normal range representing an allowable range in which the vehicle 10 can normally travel; and a change section 35 that changes the normal range on the basis of the distribution of the normal travel feature amount representing the state of the road surface, which is extracted from each of a plurality of images obtained in a period in which the vehicle 10 normally travels.SELECTED DRAWING: Figure 3
【課題】車両の通常走行を妨げる異常の検知精度を向上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の周囲を表す画像を、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入力することで特徴量を抽出する抽出部31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、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32と、車両10が通常走行した期間内に得られた複数の画像のそれぞれから抽出された、路面の状況を表す通常走行特徴量の分布に基づいて正常範囲を変更する変更部35を有する。【選択図】図3
