Das Tracking von Bewegungen eines Benutzers ist eine h\u00e4ufig verwendete Technik, um die Interaktion mit virtuellen Welten zu erm\u00f6glichen. Professionelle Trackingsysteme (siehe WorldViz-Tracking) sind jedoch sehr teuer. Hauptziel dieses Teilprojektes ist es eine low-cost L\u00f6sung zu entwickeln, die in der Lage ist, den Benutzer mit der virtuellen Welt interagieren zu lassen.<\/p>\n

\"\"
\nZwei herk\u00f6mmliche stereoskopisch ausgerichtete USB-Webcams mit IR-Bandpassfilter kommen hierbei zum Einsatz. Mit Hilfe der Kalibrierungsmethoden aus der OpenCV-Bibliothek erf\u00e4hrt das Tracking-System eine – im Idealfall – einmalige Kalibrierung. Mit aktiven Infrarotmarkern lassen sich mehrere Markerbewegungen im Raum ohne Verdeckung verfolgen. Die Routinen f\u00fcr die Kalibrierung, das Blobtracking und die 3D-Koordinatenberechnung sind vom VRlab-Team konzipiert und implementiert und funktionsf\u00e4hig. Die Tracking-Daten k\u00f6nnen von Anwendungen \u00fcber eine VRPN-Schnittstelle abgegriffen werden.<\/p>\n
