Abstract
In production metrology structured light scanners are widely used for the analysis of geometrical deviations of work-pieces. With the working principle of active triangulation the geometry can be digitized with high speed and precision. The active triangulation relies on a bijective mapping of projector—and camera pixels from a sequence of projected patterns. Especially on shiny and concave surfaces this one to one mapping is hard to calculate because of multi-reflections. With a test regarding this bijectivety a quality criterion is introduced to prevent the use of false 3D data. The criterion is tested on the scan of a reference work-piece with two crossing concave groves. Finally, a semi-manual method is shown to enhance the quality of the scanning by subdividing the surface for partial scans.
