The embodiment of the invention provides a lane departure prompting method and device, and the method comprises the steps: obtaining an image of a current lane and a vehicle positioning point; extracting two adjacent lane side lines according to the image of the current lane, and calculating a lane center line according to the two adjacent lane side lines; and calculating the distance between thevehicle positioning point and the lane center line, and if the distance is greater than a preset distance threshold, sending a lane departure prompt. The two adjacent lane side lines are extracted through the image of the current lane collected by the camera, and then the lane center line is calculated according to the two adjacent lane side lines. Then, the distance between the vehicle positioning point and the lane center line is calculated, whether the vehicle deviates from the lane or not is judged, a voice prompt is given out when the vehicle deviates from the lane, a steering prompt arrow is projected to the front windshield through the HUD, a driver can conveniently and rapidly know how to correct the direction, and traffic accidents are prevented.

    本发明实施例提供一种偏离车道提示方法及装置,其中,该方法包括:获取当前车道的影像以及车辆定位点;根据当前车道的影像提取两条相邻车道边线,并根据两条相邻车道边线计算车道中心线;计算车辆定位点与车道中心线之间的距离,若所述距离大于预设距离阈值,则发出车道偏离提示。本发明通过摄像头采集的当前车道的影像提取两条相邻车道边线,进而根据两条相邻车道边线计算车道中心线。接着,计算车辆定位点与车道中心线之间的距离,判断车辆是否偏离车道,在车辆偏离车道时发出语音提示,并通过HUD将转向提示箭头投影至前挡风玻璃上,方便驾驶员快速了解如何纠正方向,防止发生交通事故。
