Measurement Uncertainty Analysis Using Virtual Fringe Projection Based on Polygon Models

Virtual sensor systems can be applied to verify the measurability and for measurement uncertainty inspections. This can be done parallel to the component construction. It is possible, for example, to decide if all relevant workpiece surfaces can be measured with the required measurement uncertainty. In this article a method for the estimation of real measurement uncertainties is presented using a numerical computer simulation. To verify the quality of the virtual measurement system, the estimated uncertainties are in addition compared to uncertainties estimated using empirical methods.
