Scalable, non-intrusive person tracking and counting solution using time-of-flight cameras

Résumé des résultats (Abstract) (Allemand)

The goal of this project is to develop a people tracking system employing multiple time-of-flight cameras. This system is intended to replace the mechanical and/or optical turnstile based systems, providing higher functionality at a lower overall cost. Time-of-flight cameras are a new technology which has several advantages over traditional cameras, most importantly for this application; they simplify the notoriously hard problem of background to foreground separation in real time video. One drawback of time-of-flight cameras is the small field of view. In this project, this disadvantage is circumvented by employing an array of these cameras in such a way, that a much larger field of view results. Since each camera is coupled with a computing unit, local decisions are made at each camera, and only those decisions need to be feed to the supervisor for the final tracking of the people over several cameras.
