Paper Abstract

This paper describes the practical aspects of CCD-line set up and calibration for a 3D Objectscanner based on shape from stereo which was designed and produced at our Institute. This calibration is important if one wants to achieve best results with a scanner. We present an imaging system based on a single CCD-linear sensor and we provide a two-step self-calibration procedure. The results of our calibration method allows to measure object points of an accuracy better than 0.1 mm in 3D space. The self-calibration is repeatable and is suitable to be performed at the users site by using the 3D Objectscanner and the 3D calibration target.
