Abstract
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.

N1 - Funding information: In addition to the estimation of uncertainties it is possible to use the virtual measurement system as part of an assistance system. The assistance system should provide measurement strategies with respect to different criteria, like minimization of the measurement uncertainty, minimization of the time or a hollistic measurement of the workpiece [8; 9]. This is the field of research of the subproject B5 “Complete Geometry Inspection” of the collaborative research centre 489 (CRC 489) “Process Chain for the Production of Precision Forged High Performance Components”, funded by the German Research Foundation (DFG). The main task is to setup a virtual assistance system consisting of a fringe projection system, a shadow projection system and a system of linear axes. The assistance system should be used to calculate the uncertainty arising within the determination of geometric values. Furthermore, the virtual assistance system should provide information about the suitability of one of the virtual measurement systems for the measuring task.
