The invention relates to a track data-driven highway thrown object detection and avoidance early warning method, which belongs to the technical field of traffic intelligent perception, and is characterized in that a traffic data acquisition module is used for acquiring highway vehicle position information in real time by using a non-visual sensor, and a data processing module is used for carrying out side end processing on vehicle track data; the data transmission module sends side end processing data to the cloud end, the thrown object judgment module is responsible for judging the position of a thrown object according to track characteristics, and the variable speed limit information issuing module issues position information of the thrown object to a road user through an RSU. The highway thrown object detection and avoidance early warning method provided by the invention gets rid of the dependence of thrown object detection on a visual sensor by using the vehicle real-time trajectory data obtained by the non-visual sensor, and realizes thrown object judgment and position estimation from the statistical sense by using the vehicle trajectory data, so that the accuracy of the thrown object detection and avoidance early warning is improved. The problems of low precision and high false alarm rate of traditional thrown object detection are solved. The method has the advantages of being capable of being copied and popularized and high in robustness.

    本发明涉及一种轨迹数据驱动的高速公路抛洒物检测及避让预警方法,属于交通智能感知技术领域,通过交通数据采集模块利用非视觉传感器实时采集高速公路车辆位置信息,数据处理模块对车辆轨迹数据进行边端处理,数据传输模块将边端处理数据发送至云端,抛洒物判断模块负责根据轨迹特征判断抛洒物位置,可变限速信息发布模块利用RSU向道路使用者发布抛洒物位置信息。本发明提供的高速公路抛洒物检测及避让预警方法,利用非视觉传感器获取的车辆实时轨迹数据,摆脱了抛洒物检测对视觉传感器的依赖,利用车辆轨迹数据从统计学意义上实现抛洒物判断及位置估计,解决了传统抛洒物检测精度低误报率高的问题。本发明具备可复制推广、鲁棒性强的特点。
