The invention provides a fatigue driving prevention method and system, and relates to the technical field of electronic systems. The method comprises the following steps: sequentially obtaining a plurality of to-be-detected images according to preset time, and sequentially detecting face information in each to-be-detected image; positioning an eye contour in the facial information, and calculating an eye aspect ratio according to the eye contour; when the eye aspect ratio is lower than a preset aspect ratio threshold, judging the corresponding to-be-detected image as an eye-closed image; if the plurality of continuous to-be-detected images are judged as eye closing images and the eye closing time reaches a preset eye closing duration threshold, judging that the driver is in a fatigue driving state, and sending an alarm signal; judging the eye closing degree of the driver according to the change of the eye aspect ratio, and then directly judging whether the driver is in a fatigue driving state or not. When the driver is in fatigue driving, voice warning is given out to prompt the driver to have a rest in driving, the condition of fatigue driving of the driver is avoided, and the effect of preventing fatigue driving of the driver is achieved.

    本发明提出了一种防疲劳驾驶方法及系统,涉及电子系统技术领域。该方法包括:按照预设时间依次获取多个待检测图像,并依次检测每个待检测图像中的面部信息。定位面部信息中的眼睛轮廓,并根据眼睛轮廓计算眼睛纵横比。当眼睛纵横比低于预设纵横比阈值时,将对应待检测图像判定为闭眼图像。若连续多个待检测图像判定为闭眼图像且闭眼时间到达预设闭眼持续时间阈值,则判定驾驶员处于疲劳驾驶状态,并发送报警信号。根据眼睛纵横比的变化判断驾驶员眼睛闭合的程度,继而直接判断出驾驶员是否处于疲劳驾驶状态。当驾驶员处于疲劳驾驶时,将发出语音警示,提示驾驶员驾车休息,避免出现驾驶员疲劳驾驶的情况,达到防止驾驶员疲劳驾驶的效果。
