To provide a driver condition determination method and system making it possible to upgrade the precision in determining a driver's abnormal condition.SOLUTION: A driver condition determination method includes ambient information acquisition step S1, field-of-view image acquisition step S2, an eye-catching degree distribution generation step S3 of generating a driver's eye-catching degree distribution, sight line behavior acquisition step S4 of acquiring a driver's sight line behavior, sight line determination index arithmetic step S5 of computing plural sight line determination indices of a driver, head posture acquisition step S21 of acquiring the orientation of a driver's face, and driver abnormal condition determination steps S22, S23, and S27 of determining whether a driver is in an abnormal condition. At the driver abnormal condition determination steps S22, S23, and S27, when an abnormal posture is detected but plural sight line determination indices are all normal, it is determined that the driver has intentionally relaxed his/her posture. When the abnormal posture is detected and any of the plural sight line determination indices is abnormal, it is determined that the driver is in the abnormal condition.SELECTED DRAWING: Figure 12

    【課題】運転者の異常状態の判定精度を向上することができる運転者状態判定方法及びその装置を提供する。【解決手段】周辺情報取得工程S1と、視界画像取得工程S2と、運転者の誘目度分布を生成する誘目度分布生成工程S3と、運転者の視線挙動を取得する視線挙動取得工程S4と、運転者の複数の視線判定指標を演算する視線判定指標演算工程S5と、運転者の顔向き等を取得する頭部姿勢取得工程S21と、運転者が異常状態か否かを判定する運転者異常状態判定工程S22,S23,S27とを有し、運転者異常状態判定工程S22,S23,S27は、異常姿勢で且つ複数の視線判定指標が全て正常である場合、運転者が意図的姿勢崩れであると判定し、異常姿勢で且つ複数の視線判定指標のうちの何れかの視線判定指標が異常である場合、運転者が異常状態であると判定する。【選択図】 図12
