Abstract
A method for analyzing quality of a glazing including: generating at least one digital image of a test chart produced in reflection by an external surface of the glazing on an outside of the glazing; computation by at least one processing unit of quantities representative of the quality of the glazing based on the at least one image generated; and comparing values computed for the representative quantities with respect to reference values. The test chart exhibits a pattern including elements of closed contours arranged periodically. The representative quantities are representative of a deformation of the image of the test chart produced in reflection by the external surface of the glazing on the outside of the glazing, and the computation of a representative quantity includes the computation of a density of the elements.
