The invention relates to a vehicle distance early warning system based on Beidou and a monocular camera. The vehicle distance early warning system mainly takes a mobile terminal application as a main body. Comprising a Beidou satellite navigation receiver, a monocular camera, a data summarization module, a data processing module and an information early warning module. According to the working principle of the system, current vehicle data and front vehicle picture data are obtained through the Beidou and the monocular camera, and the data are integrated through the data summarization module; information such as the real distance and the relative speed of the vehicle is calculated in the data processing module; and the information early warning module dynamically updates a vehicle distance safety threshold value, compares the vehicle distance safety threshold value with result data of the data processing module, and carries out early warning reminding. The system has the advantages that accurate and real-time monitoring of the front vehicle is realized by using data of Beidou satellite navigation and the camera, and early warning reminding is performed according to a result of the monitoring data and a dynamic threshold value, so that the safety awareness and the reaction capability of a driver are improved, and rear-end collision accidents are effectively avoided.

    本发明涉及一种基于北斗与单目摄像头的车距预警系统,主要以移动端应用为主体。包括:北斗卫星导航接收器,单目摄像头,数据汇总模块、数据处理模块和信息预警模块组成。该系统的工作原理是,通过北斗和单目摄像头获取当前车辆数据和前方车辆图片数据,在数据汇总模块将数据进行整合;并在数据处理模块计算车辆真实车距、相对速度等信息;所述信息预警模块动态更新车距安全阈值并与所述数据处理模块的结果数据进行对比,进行预警提醒。该系统的优点是,利用北斗卫星导航和摄像头的数据,实现对前方车辆精确和实时的监测,并根据监测数据的结果,与动态阈值比对并进行预警提醒,提高驾驶员的安全意识和反应能力,有效避免追尾事故的发生。
