The invention relates to a signal lamp timing information processing method and device and a vehicle-road cooperation system. The signal lamp timing information processing method comprises the following steps: acquiring signal lamp images and image shooting time; identifying signal lamp states from the signal lamp images, wherein the signal lamp states comprise a red lamp state, a green lamp stateor a yellow lamp state; and generating timing information corresponding to the signal lamps according to the image shooting time corresponding to the signal lamp images and the signal lamp states. According to the technical scheme, a road side system can obtain the signal lamp timing information without accessing a signal lamp control system of a public security traffic management bureau, so thatsignal lamp reminding can be provided for multiple vehicles at the same time, the cases that the vehicles identify signal lamps by themselves, which causes identification errors or decision errors are avoided, and the traffic safety is improved; and in addition, the vehicles do not need to identify the signal lamps by themselves, so that the hardware cost and the calculation cost of the vehiclesare reduced.
本申请涉及一种信号灯配时信息处理方法、装置及车路协同系统,该信号灯配时信息处理方法包括:获取信号灯图像及图像拍摄时间;从所述信号灯图像中识别信号灯状态,所述信号灯状态包括:红灯状态、绿灯状态或黄灯状态;根据所述信号灯图像对应的图像拍摄时间和信号灯状态生成所述信号灯对应的配时信息。该技术方案,路侧系统无需接入公安交通管理局的信号灯控制系统,就可以获得信号灯配时信息,从而可以同时为多辆车提供信号灯提醒,避免车辆自身识别信号灯出现识别错误或决策错误,提高交通安全性。另外,由于车辆自身无需对信号灯进行识别,降低车辆的硬件成本和计算成本。
