NA5022E - Alternative Positioning

Objectives

General objective:

At the end of this course, the student shall be able to:
- know the positioning principles using "vision" sensors,
- know the alternative positionning techniques currently used in smartphones and tablets for indoor positionning.

Detailed objectives:

Vision

The objective of the course is to acquire basic knowledge on localisation solutions that rely on the exteroceptive sensors of a vehicle, be it terrestrial, aerial or maritime. The main considered sensor is vision, monocular, panoramic or stereoscopic, but use cases based on Lidar sensors will also be presented.

Signals of opportunity:

This course is aiming at providing an overview of the positioning techniques that are used in smartphones and tablets, and the challenges linked to indoor positioning. While GNSS is widely used in outdoor environments, alternate positioning techniques have to be used when entering in a building. These techniques may use different signals (e.g. mobile telephony, WiFi, Bluetooth) and different measurements (e.g. time of arrival, angle of arrival, signal strength) and also different positioning techniques (e.g. fingerprinting, particle filters, probabilistic graph models). The lectures will be completed by a hands-on lab session, where the students will collect and manipulate real life WiFi measurements to experiment with the principles of WiFi positioning.
