Visible Light Positioning (VLP) uses modulated LED luminaries to help locate a
receiver inside a building. Indoor positioning is becoming an increasingly important
service, and visible light has many advantages over other technologies used in indoor
positioning systems (IPS). However existing VLP approaches have major drawbacks
in robustness that have hindered their ability to be commercially deployed.
This work proposes and demonstrates a new way of using light signals in an indoor
localization system, titled Angular Diversity Visible Light Positioning (AD-VLP).
AD-VLP uses optics at the transmitter to create a structured overlapping light pattern
that can be used for positioning. This method is shown to have several advantages
over existing VLP approaches, including increased robustness over intensity based
techniques while still using a single element receiver.
This work also includes an experimental implementation of the proposed AD-VLP
system using existing mobile device technology. The experiments prove that
sub-meter accuracy is obtainable, even when the receiver is oriented away from the
transmitter. / Thesis / Master of Applied Science (MASc)
