The invention discloses a driving early warning method and system for detecting fatigue driving of a front vehicle. The method comprises the steps that the real-time relative distance between a vehicle and the front vehicle in the driving process and a real-time image containing the overall contour of the front vehicle are obtained; according to the obtained real-time image, in combination with the real-time relative distance between the vehicle and the front vehicle, the real-time distances between the left side and the right side of the front vehicle and lane lines on the two sides of the lane where the front vehicle is located are determined; according to the times that the real-time distance is smaller than or equal to the first set value and the comparison result of the real-time relative distance and the second preset value, whether fatigue driving exists in the front vehicle or not is judged; if yes, the vehicle sends out voice and displays an alarm to remind a driver of the vehicle that fatigue driving of the front vehicle exists. According to the obtained distance information and the fatigue driving judgment basis, whether fatigue driving exists in the front vehicle or not is automatically judged, reminding is carried out, the problem that the collision accident risk is high due to the fact that manual judgment is inaccurate or cannot be carried out is solved, and the driving safety is improved.
本发明公开了一种检测前车疲劳驾驶的驾驶预警方法及系统,该方法包括:获取驾驶过程中本车与前车的实时相对距离以及包含前车整体轮廓的实时图像;根据获取的实时图像,结合本车与前车的实时相对距离,确定前车左右两侧分别距离其所在车道的两侧车道线的实时距离;根据实时距离小于等于第一设定值的次数和实时相对距离与第二预定值的比较结果,判断前车是否存在疲劳驾驶;若存在,则本车发出语音及显示告警,提醒本车驾驶人员存在前车疲劳驾驶。本发明根据所获取的距离信息,依据疲劳驾驶判断依据,自动判断前车是否存在疲劳驾驶并提醒,避免人为判断不准确或无法进行人为判断而导致发生碰撞事故风险较高的问题,提高驾驶安全性。
