摘要
This invention relates to a method for mapping Wi-Fi fingerprints in a given geographical area. A user, provided with a receiver, sequentially collects Wi-Fi signal strength measurements by moving along the path thereof, with each measurement being constituted by a vector of RSS levels received from the various Wi-Fi access points. A graph that is representative of the path is determined from the sequence of measurements. Thanks to a geometric model of the area, a topographical characterization of the path is carried out on the basis of the previously obtained graph. The positions of the various measurements of the sequence are provided by the topographical characterization and stored with said measurements in a database.
