To provide a crew member monitoring device capable of accurately detecting the abnormal state of a vehicle crew member.SOLUTION: A crew member monitoring device 1 includes a calculation unit 12 for calculating the eye opening degree of a crew member aboard a vehicle and a determination unit 13 for determining the state of the crew member on the basis of the eye closing duration time of the crew member and the minimum eye opening degree in the eye closing duration time. The calculation unit 12 excludes a time corresponding to the state in which the eye closing duration time is a prescribed time or more and the minimum eye opening degree is larger than a prescribed value of the eye closing duration time from the eye closing time used for the calculation of PERCLOS. The determination unit 13 may determine the drowsiness of the crew member on the basis of the PERCLOS indicating the ratio of the eye closing time per unit time.SELECTED DRAWING: Figure 2

    【課題】車両の乗員の異常状態を精度よく検出することができる乗員監視装置を提供する。【解決手段】乗員監視装置1は、車両に乗車している乗員の開眼度を算出する算出部12と、乗員における閉眼の継続時間と閉眼の継続時間内での最低開眼度とに基づいて乗員の状態を判定する判定部13と、を備える。算出部12は、閉眼の継続時間のうち、閉眼の継続時間が所定時間以上かつ最低開眼度が所定値よりも大きくなる状態に該当する時間をパークロスの算出に用いる閉眼時間から除外し、判定部13は、単位時間あたりの閉眼時間の割合を表すパークロスに基づいて乗員の眠気を判定してもよい。【選択図】図2
