Inspecting large areas with a white light interferometer is time-consuming. To shorten inspection times, additionally, a coarser sensor can be used
in a preceding step to identify possible defects. These are afterwards accurately measured with the white light interferometer. Often, several points
of interest can be grouped and scanned with a single white light interferometer measurement. Grouping approaches found in the literature show
potential for further improvement. In this paper, a novel algorithm for view planning concerning a two-step inspection is presented. Respective
literature is reviewed and discussed. Afterwards, the functionality of the algorithm is demonstrated through an example and its performance is
evaluated based on comparison to other solutions. The approach generates results that are promising for reducing inspection times further than
other approaches.
