Abstract

The demand for high accuracy, for example in 3D-measurements or in quality control, requires high precision calibration of CCD-cameras. In this paper we present a test-field-based high-precision calibration procedure with the focus on the techniques which enable an autonomous calibration: automatic control of the imaging process with geometric tests, algorithms for automatic point detection and matching, automatic determination of approximate values for the orientation parameters and automatic model selection of the interior orientation parameters. Finally, the parameters are estimated in an iterative least squares adjustment.
