SYSTEM AND METHOD FOR LOCATION-BASED SERVICE FOR NAVIGATING INDOORS

摘要

Disclosed are a system and a method for a location-based service for navigating indoors. The system for a location-based service according to the present invention comprises: a plurality of access points; a mobile terminal, which is connected to at least one of the plurality of access points, receives a Wi-Fi signal transmitted from the access point, and forms a first Wi-Fi fingerprint using the received Wi-Fi signal; and a navigation service server, which is connected to the mobile terminal, generates a plurality of Wi-Fi radio maps that correspond to a plurality of second Wi-Fi fingerprints by using the plurality of second Wi-Fi fingerprints that correspond to a plurality of indoor locations, selects, from the plurality of Wi-Fi radio maps, a Wi-Fi radio map for estimating the location of the mobile terminal, and estimates the location of the mobile terminal from the second Wi-Fi fingerprint that corresponds to the first Wi-Fi fingerprint, on the basis of the selected Wi-Fi radio map.
