The invention provides a driver condition estimation device and a driver condition estimation method, which can quickly and accurately capture abnormal omen of a driver that cannot drive. The driver condition estimating device includes a head movement measuring unit (21) and a detector (30). The head movement measuring unit measures movement of the head of a driver from output of a driver camera (10) that photographs the driver. The detector detects a sign of abnormality of the driver from the movement of the head measured by the head movement measuring unit (21). The detector (30) determines existence of the sign of abnormality of the driver in a case in which lateral acceleration acting on the head of the driver is a predetermined value or less, by these processes: calculation of a periodic feature amount from time series data showing the movement of the head of the driver, calculation of a time series variation pattern from the obtained periodic feature amount, and comparison of the obtained time series variation pattern with a predetermined threshold.

    一种驾驶员状态估计装置和驾驶员状态估计方法,迅速且高精度地捕捉驾驶员的导致无法驾驶的异常预兆。驾驶员状态估计装置具备:头部行为检测部(21),根据对驾驶员进行摄影的摄像机(10)的输出来探测驾驶员的头部的行为;以及探测部(30),根据由头部行为检测部(21)检测出的头部的行为探测驾驶员的异常预兆。探测部(30)在作用于驾驶员的头部的横向加速度为规定值以下的情况下,针对表示驾驶员的头部的行为的时间序列数据运算周期性特征量,针对得到的周期性特征量运算时间序列变动模式,将得到的时间序列变动模式与规定的阈值进行比较,判定有无驾驶员的异常预兆。
