The invention provides a method for determining a traffic signal switching point, and relates to the technical field of artificial intelligence, in particular to the technical fields of map navigation, automatic driving, intelligent traffic and the like. The method comprises the steps that based on vehicle track information associated with a target intersection, multiple time differences between first signal switching points of multiple reference signal lamps and second signal switching points of the target signal lamp are determined, the reference signal lamps and the target signal lamp are located at the target intersection and indicate passing signals in different driving directions, and the target signal lamp is located at the target intersection; the first signal switching point and the second signal switching point have an association sequence relation and are different in signal switching type; obtaining a plurality of first moments corresponding to the first signal switching points of the plurality of reference signal lamps, and determining a plurality of first estimation moments corresponding to the second signal switching points of the target signal lamp based on the plurality of first moments and the corresponding time differences; and fusing the plurality of first estimation moments to obtain a fused target moment, the target moment being a switching moment corresponding to the second signal switching point of the target signal lamp. The method improves the efficiency and accuracy of determining the traffic signal switching point information of the target signal lamp.

    本公开提供了一种交通信号切换点的确定方法,涉及人工智能技术领域,具体涉及地图导航、自动驾驶、智能交通等技术领域。该方法包括:基于与目标路口关联的车辆轨迹信息,分别确定多个参考信号灯的第一信号切换点与目标信号灯的第二信号切换点之间的多个时间差,其中,参考信号灯与目标信号灯均位于目标路口并指示不同行驶方向的通行信号,第一信号切换点和第二信号切换点具有关联顺序关系且信号切换类型不同;获取多个参考信号灯的第一信号切换点对应的多个第一时刻,并基于多个第一时刻和对应的时间差,确定目标信号灯的第二信号切换点对应的多个第一估计时刻;将多个第一估计时刻进行融合,得到融合后的目标时刻,其中,目标时刻为目标信号灯的第二信号切换点对应的切换时刻。该方法提升了确定目标信号灯的交通信号切换点信息的效率以及准确性。
