Method and system for intelligently playing back historical tracks

Abstract

The invention discloses a method for intelligently playing back historical tracks, which comprises the following steps of: acquiring historical positioning data of a user in a timing / real-time manner,judging feature tags of data except normal movement, and cleaning the acquired historical positioning data according to the feature tags, wherein the feature tags comprise aggregation, disappearance,initialization and interruption; and processing the historical track playback progress bar in combination with the cleaned historical positioning data, adding feature point position marks or featureinterval position marks to the state position points with the feature tags, and linking each feature point position mark or each feature interval position mark to the corresponding playing progress position. According to the method, the problems that hardware resources are consumed when the positions of the positioning points in the map are updated, meanwhile, the historical track data capacity inthe map cannot be effectively increased, and the display effect is poor can be effectively solved, and the visual examination is good.

Description

technical field [0001] The invention relates to the technical field of positioning display, in particular to a method and system for intelligently replaying historical tracks. Background technique [0002] In the positioning industry, positioning accuracy and positioning capacity are relatively prominent issues. The increase in positioning capacity will also increase the pressure on historical data display, effectively solving the problem of historical trajectory data pressure and optimizing the way of large-capacity data display. It can solve the user data viewing experience in large-scale positioning scenarios. [0003] For example, in the existing exercise recording APP, the recorded exercise trajectory is usually displayed to the user in the form of a graph, but the displayed graph only includes the start time, the end time, and the places the user has been to during this period, including information The content is too small to effectively combine location and time, an...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a method and system for intelligently replaying historical trajectories. Through the data cleaning and design data display method, it effectively solves the problem of consuming hardware resources when updating the location of anchor points in the map, and at the same time causing historical trajectories in the map. The capacity cannot be effectively increased and the display effect is not good. This method can effectively solve the problem of historical track data capacity in the map and the problem of high hardware resource consumption, and the visual physical examination is good, which has good application value
