Verfahren und Vorrichtung zum Messen der Biegung einer reflektierenden Oberfläche

摘要

The invention relates to a method for measuring the curvature of a reflective surface (2), in particular of a pane of glass (5), which curves both longitudinally and transversally. According to said method, light that is emitted from a linear light source (3) is reflected by the surface (2) and registered by a CCD camera (4). The local angle of inclination of said surface (2) is determined from the reflected light that is registered by the CCD camera (4). The invention also relates to a device for determining the curvature of a reflective surface (2), comprising a linear light source (3) and a CCD camera (4). The aim of the invention is to provide a reliable and simple method and device for determining the curvature of a surface that is at least partially reflective. To achieve this, the CCD camera is a line camera (4) and the line of said CCD camera (4) is positioned transversally to the longitudinal extent of the light source (3).
