Claim:
A method for analyzing quality of a glazing comprising: displaying a test chart; capturing a digital first image of the test chart produced in reflection by an outer surface of the glazing in a direction away from the glazing, the test chart presenting a pattern including a plurality of contrasted elements defining between them interface lines; calculating, via a processing unit, values for quantities representative of the glazing from the first image; and comparing the calculated values for the quantities relative to reference values, wherein the quantities are representative of deformation of the first image of the test chart produced in reflection by the outer surface of the glazing, and wherein the values for quantities include one or more of: a quantity representative of a value for orientation of at least one line representative of a principal orientation of at least one contrasted element, a quantity representative of a local variation of the orientation of at least one line representative of a principal orientation of at least one contrasted element, a quantity representative of a dimension of at least one contrasted element, and a representative quantity of a local variation relative to a dimension of at least one contrasted element.
