The invention relates to the technical field of intelligent vehicle automatic driving, and discloses a collision early warning system based on fusion of a foresight camera and a rear millimeter wave radar, and the system comprises a visual detection module which is used for shooting and processing a road condition image in front of an intelligent vehicle, and obtaining the front road condition information; the rear millimeter wave radar is used for acquiring rear obstacle information of the intelligent vehicle by a user, and the rear obstacle information comprises obstacle speed; the data processing module is used for processing the road condition information and the rear obstacle information and comprises a rear early warning processing unit, and the rear early warning processing unit is used for obtaining collision time according to the relative speed of the rear obstacle and the intelligent vehicle in the y direction and giving an alarm when the collision time reaches a rear collision threshold value. According to the scheme, safe driving of the intelligent vehicle is guaranteed through the front-back early warning function, the probability of collision of the vehicle is greatly reduced, and the driving safety of the intelligent vehicle is improved.
本发明涉及智能车辆自动驾驶技术领域,公开了一种基于融合前视摄像头和后毫米波雷达的碰撞预警系统,包括视觉检测模块,用于拍摄智能车辆前方的路况图像并处理,获得前方路况信息;后方毫米波雷达,用户获取智能车辆后方障碍物信息,所述后方障碍物信息包括障碍物速度;数据处理模块,用于对上述路况信息以及后方障碍物信息进行处理,包括后方预警处理单元,所述后方预警处理单元用于根据后方障碍物与智能车辆在y方向的相对速度获得碰撞时间,当碰撞时间到达后方碰撞阈值时进行报警。本方案前后预警功能保证了智能车辆的安全行驶,大大降低了车辆发生碰撞的概率,提高智能车辆行驶的安全性。
