Abstract

The invention provides a trajectory data processing method and device, a storage medium and an electronic device, and the method comprises the steps: determining the first trajectory data of a to-be-queried first object in a target time period, and the first trajectory data comprises a data collection point passed by the first object; acquiring a plurality of second trajectory data of a pluralityof second objects, the second objects passing through the data acquisition points, and the second trajectory data being trajectory data of the target time period; and respectively determining the similarity between the plurality of second trajectory data and the first trajectory data to obtain a plurality of similarities, and outputting the second trajectory data of which the similarity is higherthan a preset threshold value, and by adopting the technical scheme, the problem that the trajectory data cannot be calculated and analyzed in real time in related technologies is solved. The problemsof difficult query and low accuracy of peer analysis results and the like are solved, so that real-time calculation and analysis of the trajectory data are realized, the accuracy of real-time peer analysis is improved, and the query efficiency is improved.

Description

technical field [0001] The present invention relates to the field of trajectory analysis, in particular to a method and device for processing trajectory data, a storage medium, and an electronic device. Background technique [0002] With the popularization of intelligent electronic terminal products, a large amount of trajectory data is generated in the use of smart devices, and then the similarity of the trajectory data of moving targets can be analyzed to confirm whether there is a peer situation between smart devices, and further, it can also be extracted Similar paths in trajectory data, predicting the paths of similar objects that exist. [0003] Therefore, trajectory data is widely used in various fields of trajectory analysis. In related technologies, a peer analysis method, device, equipment and medium are proposed to describe the accompanying relationship between points and point trajectories through Euclidean distance. The method of point co-occurrence times, when...
