The invention discloses a medium-high frequency GPS track data processing method and device, a storage medium and a terminal, and the method comprises the steps: determining and preprocessing historical medium-high frequency GPS track data, and obtaining an adjacent GPS track point sequence; calculating an included angle and an average driving speed of each track point in the sequence, and marking GPS track points belonging to a preset first abnormal type according to the included angle and the average driving speed; calculating a target distance between adjacent track points in the sequence, and marking GPS track points belonging to a preset second abnormal type according to the target distance; calculating a trajectory jump frequency between adjacent trajectory points in the sequence, and marking GPS trajectory points belonging to a preset third abnormal type according to the trajectory jump frequency; and determining the number of abnormal types of each marked GPS track point, and determining abnormal track points based on the number of the abnormal types for filtering or repairing. Therefore, according to the embodiment of the invention, the quality and precision of the overall GPS trajectory data can be improved, the data noise and error are reduced, and the service accuracy of an upper-layer application is improved.

    本发明公开了一种中高频GPS轨迹数据处理方法、装置、存储介质及终端,方法包括:确定并预处理历史中高频GPS轨迹数据,得到相邻的GPS轨迹点序列;计算序列中各个轨迹点的夹角和平均行驶速度,根据夹角和平均行驶速度标记属于预设第一异常类型的GPS轨迹点;计算序列中相邻轨迹点之间的目标距离,根据目标距离标记属于预设第二异常类型的GPS轨迹点;计算序列中相邻轨迹点之间的轨迹跳跃频率,根据轨迹跳跃频率标记属于预设第三异常类型的GPS轨迹点;确定标记的每个GPS轨迹点的异常类型数量,基于异常类型数量确定出异常轨迹点进行过滤或修复。因此,本申请实施例可提升整体GPS轨迹数据的质量和精度,降低数据噪声和误差,从而提升上层应用的服务准确度。
