PROBLEM TO BE SOLVED: To provide a sight line direction estimation device and a sight line direction estimation method which estimate a sight line direction of a driver of a vehicle with high accuracy.SOLUTION: A sight line direction estimation device comprises: a sight line direction estimation unit 22 which estimates a sight line direction of a driver on the basis of a face image of the driver who is driving a vehicle; a front direction determination unit 23 which determines whether the driver is seeing a front direction; a reference direction estimation unit 26 which estimates a reference direction on the basis of the sight line direction estimated during a period in which the driver is determined to be seeing the front direction; and a sight line direction correction unit 24 which corrects the sight line direction estimated by the sight line direction estimation unit on the basis of the reference direction estimated by the reference direction estimation unit.SELECTED DRAWING: Figure 2

    【課題】車両の運転者の視線方向を高い正確度で推定する視線方向推定装置及び視線方向推定方法を提供する。【解決手段】視線方向推定装置は、車両を運転中の運転者の顔画像に基づいて、当該運転者の視線方向を推定する視線方向推定部22と、運転者が正面方向をみているか判定する正面方向判定部23と、運転者が正面方向をみていると判定された期間に推定された視線方向に基づいて、基準方向を推定する基準方向推定部26と、基準方向推定部により推定された基準方向に基づいて、視線方向推定部により推定された視線方向を補正する視線方向補正部24と、を備える。【選択図】図2
