Abstract
A method for reading symbols forming a code, the symbols each being marked on one face of a number of glass sheets in proximity to the same edge face of the glass sheets, the glass sheets being arranged in a stack. The method includes acquiring, with a camera, at least one image via the edge face of the glass sheets, the observation direction being non-perpendicular and inclined relative to the edge face of each of the glass sheets the code of which is read with the image; and an image processing step in which the acquired image is processed by a processor programmed to extract information present in at least one code visible in the image and having to be read.
