The invention relates to the technical field of safe driving, and provides a night overtaking safety prompting method which comprises the following steps: acquiring rear road condition image information and front road condition image information of a vehicle in real time; according to the rear road condition image information, whether vehicles exist behind the vehicle or not is monitored in real time, and according to the front road condition image information, whether vehicles and/or pedestrians come in the opposite direction or not in front of the vehicle or not is monitored in real time; when a vehicle is behind the vehicle, whether the vehicle behind has an overtaking intention or not is judged according to the rear road condition image information; and when the rear vehicle has the overtaking intention and the vehicle and/or the pedestrian in the opposite direction are in front of the vehicle, projecting the overtaking intention of the rear vehicle to the lane in front of the vehicle and/or the pedestrian in the opposite direction in the form of a warning image. According to the method, the DLP projection technology is utilized, the overtaking intention of the vehicle behind the vehicle is projected to the lane in the form of the warning image, so that early warning is performed on vehicles and/or pedestrians coming in the opposite direction, and the occurrence rate of traffic accidents is reduced.
本发明涉及安全行车技术领域,提供一种夜间超车安全提示方法,方法包括:实时采集本车的后方路况图像信息和前方路况图像信息;根据后方路况图像信息,实时监控本车后方有无车辆,根据前方路况图像信息,实时监控本车前方有无反方向来车和/或行人;当本车后方有车辆时,再根据后方路况图像信息,判断后方车辆是否具有超车意图;当后方车辆具有超车意图,且本车前方有反方向来车和/或行人时,将后方车辆的超车意图以警示图像的形式投影至反方向来车和/或行人前的车道上。本发明通过利用DLP投影技术,将本车后方车辆的超车意图以警示图像的形式投影至车道上,从而对反方向来车和/或行人预警,从而降低交通事故的发生率。
