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.

Abstract: The invention describes a method for measuring the shape of a reflective surface (14) and a corresponding system which has at least one pattern (15) for reflection at the reflective surface (14) and at least one camera (1) for viewing the pattern (15) which is reflected at the surface (14) pixel by pixel, wherein the position and orientation of the camera (1) and of the pattern (15) are known. In order to reliably measure the shape of reflective surfaces with a small amount of equipment complexity, the viewing directions of the camera (1), which are known for the pixels (8), and the positions of the pattern (15), which correspond to the mapping of the reflected pattern (15) to pixels (8) of the camera (1), are used to determine the surface angle and surface height for the purpose of measuring the shape.

Abstract: The invention relates to a device and a corresponding method for detecting scratches on the surface (2) of a material, in particular glass. Said device comprises an illumination unit (3) and a recording unit (4), which register a scanning line (6) on the surface (2) of the material and can be displaced in relation to said surface (2). In order to more accurately identify scratches, the illumination unit (3) comprises at least one light strip (9), which generates parallel light pools transversally to the scanning line (6), said pools being diffuse or quasi-diffuse along the scanning line (6) and preferably at least one light source (16), which generates a diffuse or quasi-diffuse light transversally to the scanning line (6).
