A computer-implemented method and system for determining the geographical location of a user based on the characteristics of intersecting features, such as a road intersection. Specifically, the geometry of each intersection in a geographical area is used to derive a unique fingerprint for each individual intersection, the fingerprint comprising information relating to the geometry, the geographical location of the intersection, and other characteristics. These fingerprints can then be stored locally to a device, for example, a mobile phone, a tablet, a wearable computing device, an in-vehicle infotainment (IVI) system and the like. To determine the geographical location of the device, the geometry of a nearby intersection may be analysed by some means and compared to the stored set of unique fingerprints to identify the intersection and its associated location.
A computer-implemented method of geolocation, the method comprising:
A computer-implemented method of determining the geographical location of a user based on the geometry of intersections, wherein the geometry of a plurality of intersections in a geographical area is used to derive a plurality of unique fingerprints corresponding to the plurality of intersections, each fingerprint comprising information relating to the geometry and the geographical location of an intersection, and wherein the geometry of an intersection of unknown location is measured and compared to the plurality of unique fingerprints to determine the location thereof.
A system comprising:
