To provide an oversight detection device that appropriately detects oversight of a driver's risk depending on a surrounding situation.SOLUTION: An oversight detection device 1 comprises: a surrounding area monitoring sensor 10 for monitoring a surrounding state of a vehicle; an in-vehicle camera 13 for photographing a driver; a risk level calculation unit 14 for obtaining a risk level in each direction viewed from the vehicle on the basis of data on the surrounding condition obtained by monitoring by the surrounding area monitoring sensor 10; a gaze ratio calculation unit 15 that detects a gaze ratio according to each direction by calculating a gaze target that the driver gazes within a predetermined time and a gaze time thereof on the basis of an image captured by the in-vehicle camera 13 and by specifying a direction in which the gaze target is present; and an oversight detection unit 16 for calculating a risk of an oversight on the basis of the risk level according to the direction and the gaze ratio obtained by the gaze ratio calculation unit 15, and for detecting an oversight of the risk when a possibility of the oversight risk is greater than or equal to a predetermined threshold value in either direction.SELECTED DRAWING: Figure 1

    【課題】周辺状況に応じて、運転者のリスクの見落しを適切に検知する見落し検知装置を提供する。【解決手段】見落し検知装置1は、車両の周辺状況を監視する周辺監視センサ10と、運転者を撮影する車内カメラ13と、周辺監視センサ10にて監視して得られた周辺状況のデータに基づいて、車両から見た方向別のリスクレベルを求めるリスクレベル計算部14と、車内カメラ13にて撮影した映像に基づいて所定時間内に運転者が注視した注視対象及びその注視時間を計算し、注視対象の存在する方向を特定することで方向別の注視割合を検出する注視割合計算部15と、方向別のリスクレベルと注視割合計算部15にて求めた注視割合とに基づいてリスク見落しの可能性を計算し、いずれかの方向においてリスク見落しの可能性が所定の閾値以上である場合にリスクの見落しを検知する見落し検知部16とを備える。【選択図】図1
