Abstract

Das Ziel dieser Arbeit ist es die Effizienz eines Lichtschnittsensors in Verbindung mit einem Drehtisch zum Zwecke der 3D Rekonstruktion von technischen Bauteilen zu untersuchen. Hierzu wurde ein komplettes Messsystem entworfen, implementiert und getestet. Es wurde ein neues Konzept zur Kalibration erdacht, die dazu notwendigen Kalibrationsobjekte gefertigt und die Kalibrationsmethode implementiert. Dazu sind 2 Schritte erforderlich: die Kalibration des Lichtschnittensors; und die Registration der Drehachse relativ zur Laserebene. Das gesamte System, die optische Messeinrichtung, die Steuerung des Drehtisches und die 3D Oberflaechenrekonstruktion wurden implementiert und wurden an einer Reihe von technischen Bauteilen getestet. Die gewonnenen Messdaten koennen auch in Form eines STL Datenformats fuer ein CAD Programm nutzbar gemacht werden.
