The invention relates to a roadside sensing system, which belongs to the technical field of communication, and comprises a plurality of sensing units; an edge fusion calculation unit performs fusion calculation on the data acquired by each sensing unit to obtain a first calculation result; fusion calculation is carried out on the data acquired by the plurality of sensing units to obtain a second calculation result; the second calculation result is respectively sent to the RSU, the central cloud platform and the MEC; the RSU receives the second calculation result and sends the second calculation result to the vehicle end; and the central cloud platform and the MEC receive and store the second calculation result. The problem that existing roadside sensing is not accurate enough can be solved. Through a two-stage fusion mode of original data, higher requirements of the vehicle-road cooperation vehicle end for road end information positioning precision can be guaranteed. Meanwhile, higherrequirements of the vehicle-road cooperation vehicle end on the time delay of the road end information can be guaranteed; and the uniqueness of the identification result of the same traffic target bythe plurality of sensing units corresponding to the same sensing range is ensured.

    本申请涉及一种路侧感知系统,属于通信技术领域,该系统包括:多个感知单元;边缘融合计算单元对每个感知单元采集到的数据进行融合计算,得到第一计算结果;并对多个感知单元采集到的数据进行融合计算,得到第二计算结果;将第二计算结果分别发送至RSU、中心云平台和MEC;RSU接收第二计算结果,并将第二计算结果发送至车端;中心云平台和MEC接收并存储第二计算结果;可以解决现有的路侧感知不够准确的问题;通过原始数据的两级融合方式,可以保障车路协同车端对路端信息定位精度的更高要求。同时,可以保障车路协同车端对路端信息的时延的更高要求;保证对应于同一感知范围内的多个感知单元对同一交通目标的识别结果的唯一性。
