Currently, indoor navigation has become a hotspot in the field of Location Based Service. However, there is no universal model to geocode and locate interior facilities. In this paper, the indoor space is constructed of three layers, including venue, room, and POI. Then a geocoding framework is proposed to encode each POI as a code including three parts, namely partition number, functional number and connectivity number. In contrast to most indoor navigation methods which use WIFI or RFID would necessitate extra cost of money, manpower, and maintenance, we take advantages of QR code, which is money saving and convenient, to restore the location information. Taking the library of Wuhan University as a sample area, a prototype implementing our method for indoor navigation is generated. On this basis, a mobile navigation electronic map is developed and implemented, which can provide services of indoor positioning and optimal path push in the library. |
