Paper Abstract

For the absolute and shade-free shape measurement of 3D objects with large height discontinuities, a co-axial optical sensor system with a common image plane for pattern projection and observation was proposed. Experimental results are presented that demonstrate the shape measurements of objects with a deep hole and large discontinuities.
