Hallway Based Automatic Indoor Floor Plan Construction Using Room Fingerprints

Recently several state of the art localization techniques have been proposed that use radio maps or the sensors readily available on smartphones.

Hallway based automatic indoor floor plan construction using room fingerprints.

In proceedings of the 2013 acm international joint conference on pervasive and ubiquitous computing ubicomp. The lack of digital floor plans is a huge obstacle to pervasive indoor location based services lbs. Hallway based automatic indoor floorplan construction using room fingerprints. In 25 a technique to build an indoor floor plan using room fingerprints was.

A hallway layout learning algorithm that determines the room arrangement along each hallway e g room sizes and orders using crowd based motion. Leveraging wi fi fingerprints and user motion information this system automatically constructs floorplan via three key steps. In contrast call needs two rounds of walking in the building to detect the position of the reference points. 2 hallway layout learning to estimate room sizes and order rooms along each hallway and 3 force directed dilation to adjust room sizes.

1 room adjacency graph construction to determine which rooms are adjacent. Recent floor plan construction work crowdsources mobile sensing data from smartphone users for scalability.
