To estimate a physical condition of a driver of a moving body.SOLUTION: A driver monitor 10 comprises: an image acquisition unit 12 that acquires an image of a driver of a moving body; an image recognition unit 18 that recognizes a face and hands of the driver included in the image acquired by the image acquisition unit 12; and a state estimation unit 22 that estimates a state related to a physical condition of the driver based on a positional relationship between the driver's face and hands recognized by the image recognition unit 18. The state estimation unit 22 may estimate a state of the driver's physical condition based on a duration time or an occurrence frequency of the state in which the driver's hand overlaps the driver's nose, mouth, eyes, or a position under the eyes.SELECTED DRAWING: Figure 1
【課題】移動体の運転者の体調に関する状態を推定する。【解決手段】ドライバモニタ10は、移動体の運転者を撮像した画像を取得する画像取得部12と、画像取得部12が取得する画像に含まれる運転者の顔および手を認識する画像認識部18と、画像認識部18により認識された運転者の顔と手の位置関係に基づいて、運転者の体調に関する状態を推定する状態推定部22と、を備える。状態推定部22は、運転者の鼻、口、目または目の下の位置に運転者の手が重なる状態の継続時間または発生頻度に基づいて、運転者の体調に関する状態を推定してもよい。【選択図】図1
