PROBLEM TO BE SOLVED: To provide a driver state determination device capable of accurately determining whether or not the driver state is abnormal.SOLUTION: A driver state determination device 100 includes: a recognition part 21 for recognizing a driving posture of a driver 1; a storage part 22 for storing a normal driving posture of the driver 1; a deviation amount calculation part 23a for calculating an amount of deviation between the normal driving posture and the driving posture recognized by the recognition part 21 for each of a plurality of normal driving postures stored in the storage part 22 ; a lowest deviation amount selection part 23b for selecting the amount of deviation of the lowest value from among the calculated amount of deviation as the lowest deviation amount; an accumulated value calculation part 23c for accumulating the selected lowest deviation amount and calculating a deviation amount accumulated value; and a determination part 23 for determining a state of the driver 1 as being abnormal when the deviation amount accumulated value exceeds a predetermined threshold value.SELECTED DRAWING: Figure 1
【課題】運転者の状態が異常か否かを精度よく判定することが可能な運転者状態判定装置を提供する。【解決手段】運転者状態判定装置100は、運転者1の運転姿勢を認識する認識部21と、運転者1の正常運転姿勢を記憶する記憶部22と、記憶部22に記憶された複数の正常運転姿勢のそれぞれに対して、当該正常運転姿勢と認識部21で認識した運転姿勢とのズレ量を算出するズレ量算出部23aと、算出されたズレ量のうち、最も値が小さいズレ量を最小ズレ量として選択する最小ズレ量選択部23bと、選択された最小ズレ量を積算してズレ量積算値を算出する積算値算出部23cと、ズレ量積算値が、予め定められた閾値を超えた場合に運転者1の状態が異常と判定する判定部23dと、を備える。【選択図】図1
