This abnormality detection device is provided with: a specifying unit (31) that specifies, in an image indicating the surroundings of a vehicle (10), a travel road region indicating the own lane on which the vehicle (10) is traveling; an extraction unit (32) that extracts, from the image, a feature quantity indicating a road surface condition by inputting the traveling road region of the image to a feature extractor that has been learned in advance so as to extract the feature quantity indicating the road surface condition; and a detection unit (33) that detects an abnormal situation in which the vehicle (10) cannot normally travel on the own lane when the feature amount is not included in a normal range indicating an allowable range in which the vehicle (10) can normally travel.
异常探测装置具有:确定部(31),确定表示车辆(10)的周围的图像中的、表示车辆(10)正在行驶的自身车道的行驶道路区域;提取部(32),通过向以提取表示路面状况的特征量的方式预先进行了学习的特征提取器输入图像的行驶道路区域,来从图像中提取关于行驶道路区域的该特征量;以及探测部(33),在特征量不包含于表示车辆(10)能够通常行驶的容许范围的正常范围的情况下,探测到在自身车道上车辆(10)无法通常行驶的异常状况。
