Abstract
This invention is about an imaging system that uses conventional cameras and a single laser line to perform quality control at the output of a converting machine or a press. The system uses several cameras distributed over the width of the printed sheets. Thanks to the laser line, it can reconstruct the complete image of the printed matter even when the sheets are not perfectly flat or at varying height, compensating geometric as well as photometric distortions. The use of conventional cameras results in a cost effective system.
