Research
My research subject is Experimental Mechanics and my research considers data analysis of data from optical shape measurement methods. The shape of an object in an arbitrary position and orientation is to be compared with its nominal shape defined by a CAD/CAE-model.
Currently I am active in one research project, SIVPRO 2 (Shape Inspection by Vision in Production).

Two YouTube-videos are created to show an application of my research.
