PROBLEM TO BE SOLVED: To improve correctness related to the detection of an abnormality in a driver concerning a driver abnormality detection device for detecting an abnormality in a driver of a vehicle.SOLUTION: A driver abnormality detection device includes: an imaging section (10) for capturing the image of the head of a driver of a vehicle; and at least two determination sections among a visual line determination section (23) for determining an abnormality state when the visual line direction of a driver is not within the first predetermined range on the basis of an image captured by the imaging section, an eye height determination section (25) for determining an abnormality state when the eye height of a driver is not within the second predetermined range on the basis of an image captured by the imaging section, and a head lateral position determination section (27) for determining an abnormality state when the position of a head in a vehicle width direction is not within the third predetermined range on the basis of an image captured by the imaging section. The device also includes an abnormality state determination section (29) for determining whether a driver has an abnormality or not based on the determination results of the included respective determination sections.SELECTED DRAWING: Figure 3
【課題】車両の運転者の異常を検出する運転者異常検出装置において、運転者の異常の検出に係る正確さを向上させること。【解決手段】車両の運転者の頭部を撮影する撮影部(10)と、前記撮影部が撮影した画像に基づき運転者の視線の方向が第1の所定範囲内にない場合に異常状態と判定する視線判定部(23)、又は、前記撮影部が撮影した画像に基づき運転者の眼の高さが第2の所定範囲内にない場合に異常状態と判定する眼高さ判定部(25)、又は、前記撮影部が撮影した画像に基づき前記頭部の車幅方向における位置が第3の所定範囲内にない場合に異常状態と判定する頭部左右位置判定部(27)のうち、少なくとも2つの前記判定部と、を備え、前記備えられた各判定部の判定結果に基づいて運転者に異常があるか否かを判定する異常状態判定部(29)を、更に備える。【選択図】図3
