The invention discloses an automobile anti-collision early warning device and method based on a ground projection technology, and belongs to the technical field of intelligent automobiles. According to the invention, a ground projector, a millimeter-wave radar for backward monitoring and a monocular distance measuring camera are added on the basis of the existing intelligent automobile; the intelligent automobile obtains speed and position information of a rear automobile by monitoring the rear automobile, calculates a safety distance and an early warning distance by utilizing a safety distance model, and performs anti-collision early warning on drivers of the intelligent automobile and the rear automobile by utilizing a buzzer alarm and a ground projection technology respectively. According to the invention, the risk and probability of rear-end collision during driving are reduced to a certain extent, the safety of the automobile is improved, and the safety of other automobiles is also improved.

    本发明公开了一种基于地面投影技术的汽车防碰撞预警装置及方法,属于智能汽车技术领域。本发明在已有的智能汽车基础上增加了地面投影仪和向后监测的毫米波雷达和单目测距摄像头,智能汽车通过监测后方车辆并获取后方车辆的速度和位置信息,利用安全距离模型计算安全距离和预警距离,利用蜂鸣报警器和地面投影技术分别对智能汽车和后方车辆驾驶员进行防碰撞预警。本发明在一定程度了降低了行车时追尾碰撞的风险和概率,不仅提高了自车的安全性,也提升了其他车辆的安全性。
