The invention discloses a roadside sensing data quality monitoring system and method based on vehicle-road cooperation, and the method comprises the steps: S1, receiving roadside sensing data obtained by roadside sensing equipment; obtaining a vehicle message from an intelligent vehicle-mounted unit installed in the network-connected vehicle; s2, extracting first trajectory data of the target vehicle from the vehicle message; extracting second track data of the target vehicle from the roadside sensing data; s3, analyzing and comparing the first track data and the second track data corresponding to the same target vehicle to evaluate a roadside sensing data quality evaluation value and reporting the roadside sensing data quality evaluation value to a cloud control platform; and S4, when the roadside sensing data quality evaluation value exceeds a quality threshold value, giving an alarm to the outside that the point location sensing is abnormal. The scheme focuses on the insufficiency of data quality monitoring of the roadside sensing system in intelligent network connection road infrastructure construction, effectively guarantees the reliability and accuracy of the roadside sensing data, improves the operation and maintenance guarantee capability of the roadside sensing system, and has the development prospect of popularization and application and the practical value.

    本方案公开了一种基于车路协同的路侧感知数据质量监测系统及方法,包括,S1.接收路侧感知设备获取的路侧感知数据;获取来自安装在网联车辆内的智能车载单元的车辆消息;S2.从车辆消息中提取目标车辆的第一轨迹数据;从路侧感知数据中提取目标车辆的第二轨迹数据;S3.对同一目标车辆对应的第一轨迹数据和第二轨迹数据进行分析比对以评估路侧感知数据质量评价值并上报至云控平台;S4.当路侧感知数据质量评价值超过质量阈值时,对外报警点位感知异常。本方案聚焦智能网联道路基础设施建设中路侧感知系统数据质量监测的不足,有效保障路侧感知数据的可靠性和准确性,提升了路侧感知系统的运维保障能力,具有推广应用的发展前景和现实价值。
