The invention discloses a fatigue driving early warning method and device, and the method comprises the steps: obtaining the driver information, and judging the current driver of a driven vehicle according to the driver information; obtaining continuous driving time of the current driver, and if the continuous driving time is larger than a preset value, generating an overtime early warning signal;and monitoring the facial features of the current driver in the continuous driving time and the deviation distance of the vehicle relative to the lane line in real time, and judging the fatigue stateof the current driver according to the facial features and the deviation distance of the vehicle relative to the lane line. The driver information can be obtained, whether active replacement of the driver exists or not is judged according to the driver information, statistical errors are avoided, and therefore false alarms are avoided; in addition, the fatigue state of the current driver is judged according to the facial features monitored in real time within the continuous driving duration and the deviation distance of the vehicle relative to the lane line, and compared with the prior art, the accuracy of fatigue driving prediction can be improved.
本发明公开了一种疲劳驾驶预警方法及装置,方法包括:获取驾驶员信息,根据驾驶员信息判断驾驶车辆的当前驾驶员;获取当前驾驶员的连续驾驶时间,若连续驾驶时间大于预设值,则产生超时预警信号;实时监测当前驾驶员在连续驾驶时间内的脸部特征和车辆相对于车道线的偏离距离,根据脸部特征和车辆相对于车道线的偏离距离判断当前驾驶员的疲劳状态。本发明能够获取驾驶员信息,根据驾驶员信息判断是否存在驾驶员的主动替换,不会发生统计错误,从而避免发生误报;而且本发明还根据在连续驾驶时长内实时监测的脸部特征和车辆相对于车道线的偏离距离判断当前驾驶员的疲劳状态,相较于现有技术,能够提高疲劳驾驶预测的准确度。
