Abstract
Abstract. This research project focuses on the development of an optical 3D measuring system that enables high accurate surface measurements of welding seams in order to detect impurities. The systems concept is based on a stereo camera system in conjunction with a projecting line laser. A second camera system is used as tracking or positioning component to obtain the position of the measuring systems in object space. The complete stereo laser-profile system will be used as a hand-held system. The development, optimization and testing of the system components (stereo camera system with projecting laser line and tracking component) for surface measurements as well as calibration and accuracy evaluations are the main objectives within this research project. Testing procedures and probes are constructed and evaluated to verify the results. The development considers conditions for a future adaption to underwater use.
