SYSTEM AND METHOD FOR INDOOR LOCALIZATION USING BEACONS |
摘要 |
Systems and methods are described for determining positions of indoor localization beacons without requiring a physical site survey. In a coarse positioning method, a mobile node receives beacon signals that identify rooms (such as stores in a shopping mall) in which the beacons are located. The mobile node obtains floor plan information relating to the building and estimates beacon locations based on the floor plan and beacon signal strength. The estimated beacon locations may be arranged in a predetermined geometric pattern based on the number of beacons in a room. In a fine positioning method, a mobile node recognizes its proximity to a beacon and responsively measures the distance to other beacons. Estimated beacon positions may be used to estimate the location of the mobile node using trilateration or other techniques. |
