Abstract

A method and device for performing wireless positioning, and a positioning method thereof are disclosed, the device comprising: a first demarcation unit configured to divide an initial boundary on a predetermined space, so as to divide the predetermined space into at least two An area, each of the at least two areas includes a plurality of cells, and the plurality of cells includes border cells adjacent to the initial border; a detection unit configured to detect each of the border cells in the border cells The signal characteristic value of the wireless access point, and determine the identification number set of each detected wireless access point; the second demarcation unit is configured to re-determine the at least Boundary of two areas for wireless positioning. By using the method and device of the embodiments of the present disclosure, the positioning calculation time can be reduced while maintaining high positioning accuracy.

Description

technical field [0001] The present disclosure relates to positioning technology, and more particularly, to a method and device for performing wireless positioning, and a wireless positioning method and device. Background technique [0002] In smart offices, smart city initiatives, and environment-dependent applications, indoor WiFi-based wireless positioning systems (IPS) play a very important role because GPS signals are difficult to cover indoor areas. Most WiFi-based wireless localization methods mainly consist of two phases: offline training phase and online positioning phase. In the offline training phase, a map is built by collecting and training Received Signal Strength Indication (RSSI) data of access points (APs) located at predetermined locations, and then in the online phase, this map is applied to estimate the location. [0003] At present, the commonly used wireless positioning method based on WiFi needs to use a reference point (RP) to receive the WiFi signal ...
