The invention provides a traffic light total period mining method and device, and relates to the technical field of big data, in particular to the technical field of map navigation. A specific embodiment of the method comprises the steps that target trajectory data are converted into a target image, the target trajectory data comprise trajectory data of vehicles passing through traffic lights in a target time period, and the target image represents information of at least one type of trajectory points in the target trajectory data; the reference trajectory data is converted into a reference image, the reference trajectory data comprises trajectory data of vehicles passing through traffic lights in a total reference period before the target time period, and the reference image represents information of at least one type of trajectory points in the reference trajectory data; and inputting the target image and the reference image into an image recognition model to obtain the total period of the traffic light.
本公开提供了一种红绿灯总周期挖掘方法和装置,涉及大数据技术领域,尤其涉及地图导航技术领域。该方法的一具体实施方式包括:将目标轨迹数据转换成目标图像,其中,目标轨迹数据包括在目标时间段内经过红绿灯的车辆的轨迹数据,目标图像表征目标轨迹数据中的至少一类轨迹点的信息;将参考轨迹数据转换成参考图像,其中,参考轨迹数据包括在目标时间段之前的参考总周期内经过红绿灯的车辆的轨迹数据,参考图像表征参考轨迹数据中的至少一类轨迹点的信息;将目标图像和参考图像输入至图像识别模型,得到红绿灯的总周期。
