The invention provides a data processing method and device based on a vehicle track, electronic equipment and a storage medium, and the method comprises the steps: obtaining the track data of a vehicle in a track segment, the driving distance of the track segment being smaller than a preset segmentation distance threshold value, and the driving duration of the track segment being smaller than a preset segmentation duration threshold value; sampling the trajectory data in the trajectory segment to obtain a plurality of sampling points and sampling trajectory data of each sampling point; based on the sampling track data of each sampling point, determining a straight line where the lane direction representing vehicle driving is located; according to the straight line where the lane direction is located and the sampling track data of each sampling point, obtaining a transverse distance between each sampling point and the straight line where the lane direction is located; and determining whether the vehicle has a target lane changing behavior in the trajectory segment based on the lateral distance. The technical scheme provided by the embodiment of the invention can be used in the traffic field, can display the time points and the positions of different lane changing behaviors in real time, and has very strong timeliness.
本申请提供一种基于车辆轨迹的数据处理方法、装置、电子设备及存储介质,该方法包括:获取车辆在轨迹段内的轨迹数据,轨迹段的行驶距离小于预设分段距离阈值,并且轨迹段的行驶时长小于预设分段时长阈值;对轨迹段内的轨迹数据进行采样处理,得到多个采样点以及各采样点的采样轨迹数据;基于各采样点的采样轨迹数据,确定表征车辆行驶的车道方向所在的直线;根据车道方向所在直线与各采样点的采样轨迹数据,获取各采样点与车道方向所在的直线之间的横向距离;基于横向距离确定车辆在轨迹段内是否存在目标变道行为。本申请实施例的技术方案可用于交通领域,能实时的展示发生不同变道行为的时间点和所在的位置,具有很强的时效性。
