The invention discloses a traffic event sensing method based on millimeter-wave radar data, wherein the method comprises the following steps: obtaining trajectory data collected by a millimeter-wave radar, and cleaning the trajectory data through a time data cleaner, a speed data cleaner and a coordinate data cleaner; eliminating wrong and abnormal data to obtain trajectory data fields of the vehicles, wherein the trajectory data fields comprise timestamps, position coordinates, speeds, acceleration coordinate components and vehicle categories; storing the trajectory data of the vehicles of different categories into different trackers; and judging the traffic events and recording the types, the number and the starting and ending time of various events in a current detection area. Accordingto the invention, the millimeter-wave radar is used for sensing the traffic events, the method is more stable and has strong adaptability, the performance of data acquisition is improved, the cost isrelatively low, the detection events are carried out based on the obtained cleaned data, and the sensing method has the characteristics of high efficiency and wide acquisition range.
本发明公开了一种基于毫米波雷达数据的交通事件感知方法,包括以下步骤:获取毫米波雷达所采集的轨迹数据后,利用时间数据清洗器,速度数据清洗器和坐标数据清洗器进行清洗,剔除错误和异常数据后得到车辆的轨迹数据字段包括:时间戳,位置坐标,速度、加速度坐标分量和车辆类别,并将不同类别车辆的轨迹数据存储不同的轨迹器中;进行交通事件的判别并且记录当前检测区域各类事件的发生的类别、数目和起终时间。本发明通过毫米波雷达来进行交通事件的感知,更为稳定,适应性强,并且提高了采集数据的性能,成本也相对较低,且检测事件均是基于前面所得到的清洗后的数据进行,感知方法具有高效,且采集范围广的特点。
