Abstract
A system for the optical inspection of glass panels (2) is described, with a conveying device (3) for moving a glass panel (2), and with a first inspection module (5, 6, 7), which includes an illumination device and a camera for illuminating and photographing the glass panel (2), and with a first evaluation module (8, 9, 10, 11) for evaluating the photographs of the glass panel (2). In addition, a second inspection module (5, 6, 7) is provided, which includes an illumination device or a camera for illuminating the photograph of the glass panel (2), and it is connected with a second evaluation module (8, 9, 10, 11) for evaluating the photographs taken of the glass panel, the illumination systems and/or the cameras of the first inspection module (5, 6, 7) and the second inspection module (5, 6, 7) having different designs and/or being located in different places relative to the glass panel (2), which is moved past the inspection modules (5, 6, 7) via the conveying device. The present invention also relates to a method carried out using this system (1).
