'Black box' calibration methods investigated with a virtual fringe projection system

摘要

The mathematical fundamentals of some black box calibration procedures for fringe projection system are introduced. These calibration procedures are based upon a direct mathematical transformation between the measuring volume and the image data obtained with a camera. Aided by a mathematical model of a fringe projection system various calibration procedures are compared to each other in numerical simulations. The numerical simulations facilitate statements about the attainable measuring error depending on the calibration procedure and system parameters.
