Determination of taskspecific measurement uncertainty caused by geometrical misalignments

To use a Monte Carlo approach to simulate misaligned projections and subsequent back-projection of individual CAD-model surface points, which are subsequently recombined to point clouds for the corresponding surface fitting. The approach is fundamentally different from state-of-the-art Monte-Carlo-based virtual metrology computed tomography (CT) approaches which necessitate running a complete xCT metrology chain for each individual combination of influence factor values.
