To suppress erroneous determination when an abnormality in a lens, etc. of an on-vehicle camera is diagnosed.SOLUTION: A photographing abnormality diagnostic device comprises: an image acquisition part 31 that acquires an image of the circumference of a vehicle photographed with an on-vehicle camera; a three-dimensional information acquisition part 32 that acquires three-dimensional information of the circumference of the vehicle detected by a three-dimensional sensor; a region identification part 34 that identifies a region in which a substance on the image has to be expressed on the basis of the three-dimensional information acquired by the three-dimensional information acquisition part; a reflection level detection part 35 that detects a reflection level which is a level that the substance is reflected to a prescribed region of the image by an analysis of the image; and a diagnosis part 36 determining that an abnormality occurs in a photographing with the on-vehicle camera when the reflection level in the region where the substance is expressed is the prescribed level or low.SELECTED DRAWING: Figure 3

    【課題】車載カメラのレンズ等の異常を診断するにあたり、誤判定を抑制する。【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周囲の画像を取得する画像取得部31と、三次元センサによって検出された車両周囲の三次元情報を取得する三次元情報取得部32と、三次元情報取得部によって取得された三次元情報に基づいて画像上の物体が表されているべき領域を特定する領域特定部34と、画像の解析により画像の所定の領域に物体が写っている度合いである映り度合いを検出する映り度合い検出部35と、物体が表されているべき領域における映り度合いが所定度合い以下であるときには車載カメラによる撮影に異常が生じていると判断する診断部36と、を備える。【選択図】図3
