To provide a technique which allows for appropriately detecting rough roads.SOLUTION: A rough road detection device comprises: an acquisition unit configured to acquire images captured by a camera mounted on a vehicle; a computation unit configured to compute an optical flow representing movements of feature points using a plurality of captured images captured at different points in time while the vehicle is traveling; a prediction unit configured to predict movements of the feature points used for computing the optical flow; and a determination unit configured to determine whether a road surface on which the vehicle is traveling is a bad road by comparing the optical flow with the movements of the feature points predicted by the prediction unit.SELECTED DRAWING: Figure 1

    【課題】悪路を適切に検出することができる技術を提供する。【解決手段】悪路検出装置は、車両に配置されるカメラで撮影された撮影画像を取得する取得部と、前記車両の走行中の異なる時点で撮影された複数の前記撮影画像を用いて特徴点の動きであるオプティカルフローを算出する算出部と、前記オプティカルフローの算出に用いた前記特徴点の動きを予測する予測部と、前記オプティカルフローと、前記予測部で予測された前記特徴点の動きとを比較して前記車両が通過した路面の悪路に関する判定を行う判定部と、を備える。【選択図】図1
