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. © Oldenbourg Wissenschaftsverlag.

Virtual measurement systems can be used for the estimation of measurement uncertainties during the construction and provide knowledge concerning the working principle of the measurement system. Furthermore it is possible to integrate the virtual system into an assistance tool to calculate intelligent measurement strategies with different criteria. For example, the criterion is the minimization of the measurement uncertainty. A virtual analysis of the measuring process can be accomplished using Monte-Carlo methods. This requires a high number of virtual measurements and a large amount of computing time. To have a practicable simulation tool, the simulation time has to be minimized. In this paper the numerical efficient implementation of a virtual shadow projection system as part of a virtual multisensor assistance system is explained in detail. Besides the mathematical and physical model used, an experimental verification of the simulation will be given. © Oldenbourg Wissenschaftsverlag. Source
