A computer-implemented method for measuring the three-dimensional geometry of a mineral glass-based glazing during or just after a temperature shaping operation. The method implements digital processing and calculations, based on the principles of stereocorrelation, of digital images of a random light pattern projected onto the surface of a transparent glazing. It makes it possible in particular to determine the shape or the three-dimensional geometry of a transparent glazing, the surface of which not be totally opacified and/or which radiates under the effect of temperature.

A method for temporal synchronization between an automatic movement device and a contactless detection device arranged on the automatic movement device in order to measure a physical parameter along at least one and the same defined trajectory along the surfaces of a plurality of materials to be evaluated.

An automated method measures geometric curvature deviations between dished surfaces of a plurality of materials to be assessed and a dished surface of a reference material. The method calculates, by computer, at selected points, a difference between the curvature profiles of the dished surface of each material to be assessed and a relief height or curvature profile of the dished surface of the reference material.
