Abstract
For the measurement of components geometries using fringe projection the sensor has to be calibrated. After the calibration procedure the sensor behaviour is described through a blackbox- or a physical model. This article describes first the model of the fringe projection system by means of the projective geometry in detail, with taking into account the object-sided telecentricity of the camera lens. Afterwards the calibration strategy for the identification of all system parameters is presented. The sensor model identified will be implemented as a numerical simulation into a computer program. Furthermore the simulation is combined with Monte-Carlo-methods to calculate measurement uncertainties. The simulation is planned to be used for the influence-analysis of the system parameters onto the overall measurement uncertainty of the system.
