The invention discloses a driver fatigue early warning method and device, electronic equipment and a storage medium. The method comprises the steps that under the condition that the vehicle speed is not zero, face features of a driver are acquired; calculating an eye closing degree and a mouth opening degree based on the face features; according to the eye closing degree, the preset initial eye closing degree and the preset detection time, determining the percentage of the eye closing duration in unit time; according to the mouth opening degree, the preset initial mouth opening degree and the preset detection time, the percentage of yawning duration in unit time is determined; and determining the fatigue degree of the driver according to the percentage of the eye closing duration in the unit time and the percentage of the yawning duration in the unit time, and performing fatigue early warning according to the fatigue degree. According to the technical scheme, the accuracy of driver fatigue degree detection can be improved, so that the reliability of fatigue early warning can be improved.

    本发明公开了一种驾驶员疲劳预警方法、装置、电子设备及存储介质。该方法包括:在车辆车速不为零的情况下,获取驾驶员的人脸特征;基于所述人脸特征,计算眼睛闭合程度和嘴巴张开程度;根据所述眼睛闭合程度、预设初始眼睛闭合程度和预设检测时间,确定单位时间内闭眼时长所占百分比;以及,根据所述嘴巴张开程度、预设初始嘴巴张开程度和预设检测时间,确定单位时间内打哈欠时长所占百分比;根据所述单位时间内闭眼时长所占百分比和单位时间内打哈欠时长所占百分比,确定驾驶员的疲劳程度,并根据所述疲劳程度进行疲劳预警。本技术方案,能够提高驾驶员疲劳程度检测的准确性,从而能够提高疲劳预警的可靠性。
