Abstract
V tem diplomskem delu je predstavljen primer sistema za pozicioniranje v zaprtih prostorih z uporabo NFC tehnologije. Znano je, da v zaprtih prostorih signal satelitov navigacijskim napravam ni viden, zato pozicioniranje, kot je npr. preko GPSa, ni mogoče. Delo obsega razvoj več aplikacij, vključno z Android aplikacijo na mobilnem telefonu. Uporabnik s pomočjo aplikacije na mobilnem telefonu prebere enolični identifikator iz NFC nalepke in iz strežnika pridobi trenutni položaj in seznam možnih ciljev. Nato lahko izbere cilj in aplikacija ga usmerja po najkrajši poti do cilja preko vmesnih NFC točk, ki jih na tej poti uporabnik lahko prebere. Na zaslonu telefona se prikazujejo informacije, kot so smer, oddaljenost do naslednje točke, celotna oddaljenost do cilja in trenutna hitrost. V delu so opisani matematični in fizikalni problemi in njihove rešitve. V zadnjem poglavju je bila izdelana statistična analiza, ki pripomore pri ugotavljanju anomalij vpliva močnega magnetnega polja.

Title:Indoor positioning using NFC technology
Abstract:
In this diploma thesis an example of the indoor positioning system using NFC technology is presented. The indoor signal of satellites, such as GPS, is not visible to the navigational devices, so the positioning there is not possible. The thesis covers the development of several applications including Android application for smartphones. The smartphone user reads ID from NFC label and gets his current position and the list of all possible destinations from the server. User can then select one destination and can receive the shortest path from the current position to the destination from the server. Mobile application navigates him between NFC labels on this shortest path until the destination is reached. The thesis also covers some mathematical and physical problems connected with the topic and possible solutions. In the last chapter the statistical analysis that can help find strong magnetic field anomalies is presented.

Keywords:positioning, NFC, hypothesis, sensor fusion, magnetometer, accelerometer, gyroscope, Android, graph database, Neo4J, Kalman filter, JSON, Dijkstra, computer science, diploma
