The invention relates to a traffic data cleaning method and system based on millimeter-wave radar data. The method comprises the following steps of: (1) acquiring radar reflection data of a vehicle including a radar reflection area and track data of the vehicle by using a millimeter-wave radar; (2) screening the obtained radar reflection data, and removing data with an overlarge radar reflection area; (3) carrying out continuity judgment on the radar reflection data after removal, and carrying out vehicle judgment on an object detected by the millimeter-wave radar; and (4) identifying wrong reflection data contained in the reflection data, and completing cleaning. Compared with the prior art, the method has the advantages that trajectory data is fully utilized, and wrong data judgment is more accurate.
本发明涉及一种基于毫米波雷达数据的交通数据清洗方法及系统,方法包括步骤:1)利用毫米波雷达获取包括雷达反射面积在内的车辆的雷达反射数据以及车辆的轨迹数据;2)对获取的雷达反射数据进行筛选,剔除雷达反射面积过大的数据;3)对剔除后的雷达反射数据进行连续性判断,并对毫米波雷达检测到的物体进行车辆判定;4)识别反射数据中包含的错误反射数据,完成清洗。与现有技术相比,本发明具有充分利用轨迹数据,使错误数据判断更加准确等优点。
