The invention relates to the field of direct application of the technology to vehicle safety driving, and provides a vehicle driving warning method based on a vehicle-mounted sensor. The method aims to calculate the current risk value of the vehicle body more accurately in combination with a multi-mode technology without adopting a traditional distance alarm rule. According to the main scheme, medium-range radar sensors are installed in front of and behind a vehicle respectively, the real-time speed, relative speed, acceleration, relative acceleration and distance of front and rear vehicles are calculated, cameras are arranged in the front, back, left and right directions of the vehicle, pictures are generated frame by frame by intercepting videos, and the type of the vehicle is recognized; the method comprises the following steps: integrating data shot by a radar sensor and a camera, modeling a road vehicle driving condition, and combining a constant attribute of a vehicle scanned by a radar with a vehicle type identified by the camera; carrying out comprehensive risk calculation by combining constant attributes of the vehicle, and generating a risk score of which the full score is a 100-score system; the alarm threshold exists as an alarm prompt condition and can be manually changed.

    本发明涉及本技术直接运用于车辆安全行驶领域,提供了一种基于车载传感器下车辆行驶告警方法。主旨在于不采用传统的距离告警规则,结合多模态技术对车身当前风险值进行更精准的计算。主要方案包括车辆前后方分别安装中程雷达传感器,计算前后车辆的实时速度、相对速度、加速度、相对加速度与距离,在车辆的前后左右四个方向设置摄像头,通过截取视频生成逐帧图片,识别车辆类型;综合雷达传感器与摄像头拍摄数据,对道路车辆行驶情况进行建模,将雷达扫描的车辆的常量属性与摄像头识别出车辆类型进行合并;结合车辆的常量属性,进行综合性风险计算,生成风险分值,满分为100分制;告警阈值作为告警提示条件存在,可以人为更改。
