20.500.12556/DiRROS-21386 Offline indoor navigation via QR codes This 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. cost-effective system QR codes Pedestrian Dead Reckoning indoor navigation true false true Springer Nature Švica Angleški jezik Ni določen © 2025 The Author(s), under exclusive license to Springer Nature Switzerland AG Neznano 2025-01-30 11:45:57 2025-01-30 11:45:57 2025-01-31 03:37:12 0000-00-00 00:00:00 2025 0 0 Nasl. z nasl. zaslona; Opis vira z dne 15. 1. 2025; Str. 292-296 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2024-12-30 2025-12-30 004.9 1865-0937 10.1007/978-3-031-78516-0_31 222498819 222488323 RAZ_Modic_Robert_2025.pdf RAZ_Modic_Robert_2025.pdf 1 BC2872B6CC9CE22014D56DFD9DC46847 5847d505169bf1cbc951c05c7012b803bc59eda8d656b448e2cdaadf9d92f5c1 3f199030-def8-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=30467 Institut Jožef Stefan 0 0 0
