Internet-based Indoor Navigation Services

Image Based Indoor Navigation

Over the last years researchers proposed numerous indoor localisation and navigation systems. However, solutions that use WiFi or Radio Frequency Identification require infrastructure to be deployed in the navigation area and infrastructure-less techniques, e.g. the ones based on mobile cell ID or dead reckoning suffer from large accuracy errors. In this Thesis, we present a novel approach of i...

iLOC - building indoor navigation services using Linked Data

Currently, there are hardly any indoor navigation services utilizing Linked Data, and there is also a lack of available vocabularies or ontologies for the description of building plans. This paper presents the iLOC ontology as a generic approach for in-house wayfinding and location description. The suggested Linked Data model enables the integration of various datasets related to buildings and ...

STEPPING – Smartphone-Based Portable Pedestrian Indoor Navigation

Many current smartphones are fitted with GPS receivers, which, in combination with a map application form a pedestrian navigation system for outdoor purposes. However, once an area with insufficient satellite signal coverage is entered, these navigation systems cease to function. For indoor positioning, there are already several solutions available which are usually based on measured distances ...

State-based SHOSLIF for indoor visual navigation

In this paper, we investigate vision-based navigation using the self-organizing hierarchical optimal subspace learning and inference framework (SHOSLIF) that incorporates states and a visual attention mechanism. With states to keep the history information and regarding the incoming video input as an observation vector, the vision-based navigation is formulated as an observation-driven Markov mo...
