Offline indoor navigation via QR codesModic, Robert (Avtor) Ogrinc, Matevž (Avtor) Simčič, Andraž (Avtor) Blažica, Bojan (Avtor) Torkar, Drago (Avtor) cost-effective systemQR codesPedestrian Dead Reckoningindoor navigationThis paper introduces a novel, cost-effective system for indoor navigation and localization that operates independently of satellite positioning services and data communication networks. The proposed solution leverages QR codes affixed within building interiors and an accompanying smartphone application, which, through integration with the device’s inertial motion unit (IMU) sensors and the application of the Pedestrian Dead Reckoning (PDR) algorithm [1], accurately determines the user’s position. This position data is then utilized by the Dijkstra navigation algorithm [2] to facilitate user navigation to their desired destination. Beyond navigation, this system offers significant utility in healthcare logistics, enabling efficient collection and transmission of triage decisions in emergency situations, even in the absence of a communication network.Springer Nature 20252025-01-30 11:45:57Neznano21386UDK: 004.9ISSN pri članku: 1865-0937DOI: 10.1007/978-3-031-78516-0_31COBISS_ID: 222498819OceCobissID: 222488323Švicasl© 2025 The Author(s), under exclusive license to Springer Nature Switzerland AG
