Indoor positioning method and server

Abstract

The embodiment of the invention discloses an indoor positioning method and a server. The method comprises the following steps: receiving the location measurement information of a terminal through a server, and determining N target access points and target buildings that meet the preset conditions according to the received signal information of multiple access points; determining the initial floor of the terminal according to the target access points in the target buildings and the prestored floor information of each access point; and furthermore, determining the target floor according to the initial floor and the floors on which the terminal is located at L historical moments before the current moment, and calculating the location of the terminal. As the server can further determine the target floor on which the terminal is located according to the floors on which the terminal is located at L historical moments before the current moment after determining the target building and the initial floor according to the received signal information of multiple access points, the problem of floor misjudgment caused by the excessive coverage of the access points between different floors can be effectively avoided, and the accuracy of positioning can be effectively increased.

Description

technical field [0001] The present invention relates to the field of positioning technology, in particular to an indoor positioning method and server. Background technique [0002] At present, the positioning technology of terminals in mobile communication networks has attracted more and more people's attention. The application of location-based services has flourished and penetrated into all aspects of social life, such as navigation services, location push and associated search, and big data behaviors. In the data age, various information services derived from location information will shine, which will further highlight the importance of positioning technology. [0003] The positioning technology can be divided into three categories in terms of methods: positioning technology based on triangular relationship, positioning technology based on scene analysis, and positioning technology based on proximity relationship. Among them, the positioning technology based on the prox...

AI Technical Summary

Problems solved by technology

Since the calculation of the power field strength is involved in the positioning calculation process, when there is an over-coverage situation in the positioning area, the power field strength of the over-covered access point will affect the measurement signal, resulting in misjudgment of the floor problem, which leads to serious deviations in positioning results and poor positioning accuracy
