The invention relates to the technical field of automatic driving, and discloses a data marking method, device, equipment and medium for a cut-in target, and the method comprises the steps: obtaining a self-vehicle track, a target vehicle track and lane center line information, the self-vehicle track being a track of a self-vehicle running on a current road, and the target vehicle track being a track of a target vehicle running on a current road; the target vehicle track is the track of other target vehicles near the vehicle on the current road, and the lane center line information comprises the lane center line of each lane on the current road; taking a lane center line closest to the own vehicle track at each driving moment as a calibration center line at the corresponding moment; identifying a target vehicle cut-in action according to the relative distance between the target vehicle track at each moment and the corresponding calibration center line; and marking the target vehicle corresponding to the target vehicle cut-in action and the cut-in time. According to the invention, the accuracy of data annotation for the cut-in target is improved.

    本发明涉及自动驾驶技术领域,公开了一种切入目标的数据标注方法、装置、设备及介质,方法包括:获取自车轨迹、目标车轨迹和车道中心线信息,所述自车轨迹是自车在当前道路上行驶的轨迹,所述目标车轨迹是自车附近的其他目标车在当前道路上行驶的轨迹,所述车道中心线信息包括当前道路上各个车道的车道中心线;将各个行驶时刻与所述自车轨迹相距最近的车道中心线作为相应时刻的校准中心线;根据所述目标车轨迹在各个时刻和对应的所述校准中心线之间的相对距离识别目标车切入动作;对所述目标车切入动作对应的目标车和切入时刻进行标注。本发明提高了针对切入目标的数据标注准确性。
