The invention provides a vehicle-road collaborative roadside sensing data quality evaluation method and system and related equipment. The method comprises the following steps: acquiring vehicle-mounted truth value data and roadside sensing data; unifying the data formats of the vehicle-mounted truth value data and the roadside sensing data; the timestamps of the roadside sensing data are adjusted for multiple times within a preset threshold range, and a roadside sensing track most matched with a true value vehicle track corresponding to the vehicle-mounted true value data is screened out from the roadside sensing data; and calculating the deviation precision between the true value vehicle track and the roadside sensing track under the timestamp alignment to serve as an evaluation result of the sensing precision of the roadside sensing system, and outputting the evaluation result. According to the method, the quality of the roadside sensing data is evaluated through a plurality of evaluation indexes, the quality evaluation of the roadside sensing data under vehicle-road cooperation is efficiently realized, the high-quality roadside sensing data can improve the effects of vehicle-road cooperation information service and traffic management, and thus the development of commercial vehicle, road and cloud integrated smart travel ecology is promoted.

    本发明提供一种车路协同的路侧感知数据质量评价方法、系统及相关设备,该方法包括:获取车载真值数据和路侧感知数据;统一车载真值数据和路侧感知数据的数据格式;在预设的阈值范围内多次调整路侧感知数据的时间戳,并从路侧感知数据中筛选出与车载真值数据所对应的真值车轨迹最匹配的路侧感知轨迹;计算在时间戳对齐下的真值车轨迹和路侧感知轨迹之间的偏差精度,以作为对路侧感知系统的感知精度的评价结果并输出。本发明通过多个评价指标评价路侧感知数据的质量,高效地实现了车路协同下路侧感知数据的质量评价,高质量的路侧感知数据可以提高车路协同信息服务和交通管理的效果,进而促进商业化的车、路、云一体化智慧出行生态的发展。
