The invention discloses a method for identifying a traffic signal lamp by fusing multi-source data, and the method comprises the following steps: S1, carrying out the multi-source collection of the data of the traffic signal lamp, and carrying out the data collection of the traffic signal lamp through different data collection devices or ways; s2, data preprocessing; s3, data fusion: carrying out data fusion on the weighted observation values; and S4, signal judgment and service providing: according to the fused data, judging the state of the traffic signal lamp and providing the state information of the traffic signal lamp to the vehicle and the roadside facility. According to the method, traffic signal lamp data from three different sources are fused, the most accurate traffic signal lamp state is obtained, and the defect that high safety, accuracy and real-time performance cannot be achieved at the same time when signal data collection is conducted through a single data collection device is overcome.
本发明公开了一种融合多源数据识别交通信号灯的方法,包括以下步骤:S1:交通信号灯数据多源采集,通过不同数据采集设备或途径对交通信号灯进行数据采集;S2:数据预处理;S3:数据融合,对加权后的观测值进行数据融合;S4:信号判断和服务提供,根据融合后的数据,判断交通信号灯状态并将交通信号灯状态信息提供给车辆和路侧设施。本发明本方法对三种不同来源的交通信号灯数据进行融合,得到最精准的交通信号灯状态,弥补了用单一的数据采集设备进行信号数据采集时无法兼具较高安全性、准确性和实时性的缺陷。
