Track playback method based on positioning terminal

Abstract

The invention provides a track playback method based on a positioning terminal, and the method comprises the following steps: obtaining a detailed map of a target region, drawing a walkable route frame in the map, and recording a set of all virtual marking points passed by a user through walking based on the data interaction between terminal equipment held by the user and the positioning terminalin the target region; determining a track of the user according to the set of all the virtual mark points passed by the user by walking and a shortest path algorithm; and based on the track, determining all track points actually passed by the user by adopting a sorting algorithm of adjacent points, and gradually playing back the walking track of the user according to all the track points. Based onthe fact that the positioning terminal, a bracelet or a mobile phone worn by a person or other terminal devices are installed in the region, the positioning terminal and mark points on a webpage interface are mutually mapped, and therefore the position information of the person can be displayed on the interface in real time, and the walking track of the user can be generated. And the function ofasynchronous playback of the walking track can be realized.

Description

technical field [0001] The invention relates to the field of positioning technology, in particular to a track playback method based on a positioning terminal. Background technique [0002] Traditional GPS positioning and map display cannot display the specific location of personnel in buildings and rooms, and cannot provide accurate positioning information for real-time location display and path playback under high requirements. [0003] For the location information of a small-scale specific area, the conventional method is to write the specific location information into the source code. The disadvantage is that it is difficult to correspond to the actual location of the web interface, and it is necessary to repeatedly find and adjust the virtual location of the marked terminal, adjust and update Has extremely high maintenance costs. [0004] In addition, in the prior art, after the information of the positioning points passed by the user is determined, the walking tracks a...

[0003] For the location information of a small-scale specific area, the conventional method is to write the specific location information into the source code. The disadvantage is that it is difficult to correspond to the actual location of the web interface, and it is necessary to repeatedly find and adjust the virtual location of the marked terminal, adjust and update have high maintenance costs

When querying the walking track of a user, the system must first traverse all the information of the positioning points that the user passes by, and then generate a complete walking track according to the time sequence, and then use animation to play back the walking track. The process of traversing and sorting brings The huge amount of calculations leads to slow response speed of track playback, which greatly affects the user experience
