Problems solved by technology

[0003] The accuracy of historical trajectory display is related to the reporting frequency of trajectory collection points. Under a certain scale, the more samples of collection points, the higher the accuracy of the trajectory drawn, but the number of loaded collection points is large, and the collection points loaded by the application will affect the system. However, it also reduces the accuracy of historical trajectories, and the displayed trajectories will be different from the actual trajectories obvious deviation

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0048] This application discloses a historical trajectory data loading method, the flow chart of which is as follows figure 1 shown, including:

[0049] Step S11, determining the scale data on the current map;

[0050] Step S12, determining no less than two key collection points from the historical trajectory data;

[0051] Step S13, based on the scale data, determine the on-map distance of every two adjacent key collection points on the current map;

[0052] Step S14, determine ...

Abstract

The invention discloses a historical trajectory data loading method, a device and a system thereof, and the method comprises the steps: determining key collection points on a map, and selecting auxiliary collection points between the key collection points according to a proportion based on scale data, thereby achieving the trajectory data on the map matched with the scale data, and the the problem that for maps of different proportions, operation response delay is caused by too many loaded acquisition points can be avoided, or the problem of obvious deviation between the displayed track and the actual track caused by too few loaded acquisition points can be avoided, the accuracy of the displayed track data can be improved, and the system response efficiency at the same time can be improved.

Description

technical field [0001] The present application relates to the field of information technology, and in particular to a method, device and system for loading historical trajectory data. Background technique [0002] With the rapid development of communication networks and positioning systems, the positioning data of mobile devices has become the basic data of system applications. Historical trajectory is to display the trajectory information of equipment in a period of time in chronological order, and it is widely used in public security, fire protection and other industries. [0003] The accuracy of historical trajectory display is related to the reporting frequency of trajectory collection points. Under a certain scale, the more samples of collection points, the higher the accuracy of the trajectory drawn, but the number of loaded collection points is large, and the collection points loaded by the application will affect the system. However, it also reduces the accuracy of ...
