Locatiebepaling binnen gebouwen op basis van spectrale graafanalyse

Al kennen we in Nederland een rijke kartografische en topografische geschiedenis, het publiek domein binnen gebouwen blijft een terra incognita: een grote verzameling witte vlekken. In het bijzonder voor mobiele applicaties is er nog geen weg gevonden naar automatisch werkende navigatiesystemen en het type kaart dat daaraan ten grondslag zou...

A graph-matching approach to indoor localization using a mobile device and a reference bim

The presented method provides for a possibility to perform graph-based indoor localization, by comparing the topological structure embedded in a mesh model to the topological structure of a semantically rich reference model, specifically a BIM. However different in nature and structure, both input sources can be converted to a graph of...

In_sight: Using Existing Wi-Fi networks to Provide Information on Occupancy and Exploitation of Educational Facilities using at Delft University of Technology

The distribution of people in buildings, the occupancy of lecture-, work- and study places and the accessibility of facilities are essential information at university campuses who have to cope with limited and even shrinking budgets and huge, rising real estate costs. Only little insight is gained in both occupancy and movement patterns with...
