Method for mapping wi-fi fingerprints by means of blind collection of rss measurements

Method for mapping Wi-Fi fingerprints in a predetermined geographical area, comprising:

• a step of collecting Wi-Fi signal strength measurements, with each measurement being represented by a vector constituted by the respective signal strength levels emitted by a plurality of Wi-Fi access points, with the collecting of said measurements being carried out sequentially along at least one path of a user in said geographical area, in order to provide at least one sequence of measurements;
• a step of determining a graph that is representative of the path, with each measurement of said sequence corresponding to a node or to a single point of an edge of this graph;
• a step of topographical characterisation of said path using at least said graph that is representative of the path and a geometric model of the geographical area, with the topographical characterisation associating each measurement with a point of the geometric model;
• a step of storing the sequence of measurements in a database, with each measurement stored in relation with the point of the geometric model that was associated to it in the preceding step.
