The invention provides a system and a method for synchronously displaying traffic lights at the tail of a commercial vehicle. The system comprises a camera, a navigation module, an image processing module and a data processing module, wherein the camera is used for acquiring a real-time image and a timestamp of a traffic light to be identified at a current driving intersection of the vehicle; the image processing module is used for identifying the real-time image to obtain first color information and first countdown information of the traffic light to be identified; the navigation module is used for acquiring real-time navigation information of the vehicle, and the real-time navigation information comprises second color information and second countdown information of the traffic light to be identified at the current driving intersection; and the data processing module is used for comparing the first color information and the first countdown information with the second color information and the second countdown information, and outputting calibrated traffic light information according to a comparison result. Accurate traffic light information can be provided for rear vehicles without depending on a network, the intersection passing efficiency is improved, and the traffic accident occurrence risk is reduced.
本发明提供一种商用车尾部红绿灯同步显示系统和方法,系统包括摄像头、导航模块、图像处理模块、数据处理模块:摄像头用于获取车辆当前行驶路口待识别红绿灯的实时图像及时间戳;图像处理模块用于对实时图像进行识别,得到待识别红绿灯的第一颜色信息和第一倒计时信息;导航模块用于获取车辆的实时导航信息,其中,实时导航信息包括当前行驶路口待识别红绿灯的第二颜色信息和第二倒计时信息;数据处理模块用于将第一颜色信息、第一倒计时信息与第二颜色信息、第二倒计时信息进行对比,根据对比结果,输出校准后的红绿灯信息。本发明能够在不依赖网络的情况下,为后车提供准确的红绿灯信息,提高路口通行效率,降低交通事故发生风险。
