To enable appropriate diagnosis of an abnormality such as a distorted region in an image captured by a vehicle-mounted camera.SOLUTION: The imaging abnormality diagnosis device includes: a lane marking shape detection unit 31 that detects a shape of a lane marking in an image of a road surface in front of or behind a vehicle captured by a vehicle-mounted camera; a road shape estimation unit 32 that estimates a shape of a road on which the vehicle is traveling, based on an output of a detector other than the vehicle-mounted camera; and a distortion region detection unit 33 that detects a region in the image where the shape of the road and the shape of the lane marking do not match, as a distortion region where local distortion has occurred in the image.SELECTED DRAWING: Figure 3
【課題】車載カメラによって撮影された画像内の歪み領域等の異常を適切に診断することができるようにする。【解決手段】撮影異常診断装置は、車載カメラによって撮影された車両の前方又は後方の路面の画像内の区画線の形状を検出する区画線形状検出部31と、車載カメラ以外の検出器の出力に基づいて車両が走行している道路の形状を推定する道路形状推定部32と、前記道路の形状と前記区画線の形状とが一致しない前記画像内の領域を該画像中に局所的な歪みが生じている歪み領域であるとして検出する歪み領域検出部33と、を備える。【選択図】図3
