Motion track display method and device

Abstract

The invention provides a motion trajectory display method and device. The method comprises the steps of obtaining a first position of a first object at each moment; obtaining a second position of a second object at each moment; for each moment within a preset time period, counting the distance between the first position of the first object and the second position of the second object; according tothe distance at each moment within the preset time period, generating a K-line diagram corresponding to the preset time period; displaying the K-line diagram corresponding to the preset time period when the motion trajectory of the first object is displayed according to the first positions and the motion trajectory of the second object is displayed according to the second positions. By adopting the K-line diagram to represent the motion trajectories of the different objects in time and space, the problems are solved that in the prior art, when two-dimensional planes of maps are used for showing the motion trajectories of the different objects, whether or not the different objects intersect with one another cannot be clearly and visually shown, and the efficiency is low.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method and device for displaying motion tracks. Background technique [0002] When the big data system analyzes the relationship and behavior of people and entities, it usually needs to analyze the movement trajectories of people and entities, and mine the trajectories from time and space. [0003] In the related technology, the trajectories of people and entities are usually marked by dotted lines on the map, and the map is displayed as a two-dimensional plane, which cannot express time-related information. Therefore, the trajectories of two people or entities will appear on the map However, in fact, there may be a long time interval between two people or entities appearing at the same location, that is, in fact, there is no intersection point between the two trajectories in time and space. Using a map cannot clearly show whether two objects have intersected in t...

AI Technical Summary

Problems solved by technology

[0005] For this reason, the present invention proposes a motion trajectory display method to realize the motion trajectory of different objects in time and space through the K-line diagram, which solves the problem of using the two-dimensional plane of the map to display the motion of different objects in the prior art. Trajectories, unable to express information in time and space at the same time, resulting in the inability to clearly show whether different objects intersect in time and space, which is not intuitive and less efficient
