The invention provides a pedestrian-sensing vehicle-road cooperative early warning device and method based on millimeter-wave radar, and the method comprises the steps: obtaining pedestrian data through the millimeter-wave radar by a radar data collection module, and transmitting the pedestrian data to an edge calculation module in real time through a connection port; the edge calculation module carries out real-time identification operation on the pedestrian data through a Jetson Nano development board to obtain a pedestrian distance and an ID (Identity); the data transfer module receives an identification result sent by the Jetson Nano in a WIFI wireless communication mode through the Raspberry Pi, uploads the identification result to the MQTT server, and stores the identification result locally at the same time; the MQTT server receives the data transmitted from the Raspberry Pi and sends the data to a data display module; the data display module displays the pedestrian distance and ID data obtained from the MQTT server side through the vehicle-mounted terminal APP, and judges whether operation needs to be carried out or not. The device has the advantages of small size, convenience in connection and debugging, simple structure, accurate identification result, low cost and the like, can effectively perform real-time target detection, and achieves a better vehicle-road cooperative early warning function.
本发明提出了一种基于毫米波雷达的行人感知车路协同预警装置及方法,雷达数据采集模块由毫米波雷达获取行人数据,并通过连接端口实时传输至边缘计算模块;边缘计算模块通过Jetson Nano开发板对行人数据进行实时的识别运算,获得行人距离和ID;数据转存模块由树莓派接收从Jetson Nano经过WIFI无线通信方式发送过来的识别结果,上传至MQTT服务器,同时保存在本地;MQTT服务器接收从树莓派传输过来的数据,并发送给数据展示模块;数据展示模块通过车载终端APP展示从MQTT服务器端获取的行人距离和ID数据,判断是否需要进行操作。本发明具有体积小、连接调试方便、结构简单、识别结果准确、成本低等优点,能够有效的进行实时目标检测,达到更好的车路协同预警功能。
