PhD Qualifying Examination


Title: "A Survey of Optical Indoor Localization"

by

Mr. Han XU


Abstract:

Indoor localization is of great importance to a wide range of applications, 
attracting many research efforts in the past decades. The mainstream indoor 
localization is Radio Frequency (RF)-based method due to its pervasiveness, 
however, it suffers from dramatic performance degradation in complex situations 
on account of multipath fading and temporal dynamics. Recent advances in 
Charge-coupled Device (CCD) technologies, actuator miniaturization, processing 
speed, and image understanding have been driving the development of the 
image-based localization systems. An improved performance of optical systems 
has triggered image-based localization methods to become an attractive 
alternative for applications in industrial metrology as well as for robot and 
pedestrian navigation. Together with the popularity of smartphones and the 
increasingly powerful cameras equipped, we envision a trend of pervasive 
image-based indoor localization. Besides that, the widespread of Visible Light 
Communication (VLC) makes Visible Light Positioning (VLP) become a spark that 
may start a prairie fire.

In this article, we investigate a large body of recent optical indoor 
localization systems and classify them into image-based approaches and 
VLP-based approaches. For each category, works are further classified according 
to how the user locations are referenced to the environment. Under each 
subcategory, we emphasize the basic principles and address future directions of 
research in this new and largely open area.
