The invention provides a traffic light countdown time identification method and device, and is applied to the technical field of automobiles, and the method comprises the steps: inputting a current to-be-identified traffic light picture into a pre-trained time identification model after obtaining the current to-be-identified traffic light picture, a timestamp corresponding to the current to-be-identified traffic light picture, and a plurality of historical identification results; then, taking each historical countdown time as a target historical countdown time, and according to the target historical countdown time, a timestamp corresponding to the target historical countdown time and a timestamp of the current to-be-recognized traffic light picture, obtaining a predicted countdown time corresponding to the current to-be-recognized traffic light picture; and calculating corresponding reference countdown time, and finally determining the current countdown time based on each reference countdown time and the predicted countdown time. According to the method, on the premise of not depending on a high-precision map, network connection and a traffic control information platform, the countdown time of the traffic lights is accurately recognized, and the driving safety is improved.

    本发明提供红绿灯倒计时时间识别方法及装置,应用于汽车技术领域,该方法在获取当前待识别红绿灯图片、当前待识别红绿灯图片对应的时间戳以及多个历史识别结果之后,将当前待识别红绿灯图片输入预训练的时间识别模型,得到当前待识别红绿灯图片对应的预测倒计时时间,然后分别将各历史倒计时时间作为目标历史倒计时时间,根据目标历史倒计时时间、目标历史倒计时时间对应的时间戳以及当前待识别红绿灯图片的时间戳,计算相应的参考倒计时时间,最终基于各参考倒计时间和预测倒计时时间,确定当前倒计时时间。本方法在不依赖于高精地图、网络连接以及交管信息平台的前提下,准确识别红绿灯的倒计时时间,有助于提高行车安全性。
