The invention provides a fatigue driving monitoring method and system. The method comprises the steps that camera visual information and vehicle time information are collected in real time; extracting a current driver state characteristic value from the camera visual information, and obtaining a current vehicle driving duration value and a current vehicle driving time period from the vehicle time information; the time judgment index is in positive correlation with the current vehicle driving duration value and whether the current vehicle driving time period is in a preset easy-to-trample time period or not; and judging whether the current time judgment index exceeds a first preset threshold value or not, and determining whether the driver is in a fatigue driving state or not in combination with the driver state characteristic value.

本发明提供了一种疲劳驾驶监测方法及系统，该方法包括：实时采集摄像头视觉信息以及车辆时间信息；从摄像头视觉信息中提取当前驾驶员状态特征值，从车辆时间信息获取当前车辆驾驶时长值以及当前车辆驾驶所处的时间段；时间判断指数与当前车辆驾驶时长值、当前车辆驾驶所处的时间段是否处于预设易困时间段成正相关；判断当前时间判断指数是否超过第一预设阈值，并结合驾驶员状态特征值确定驾驶员是否处于疲劳驾驶状态。
