The invention relates to a method for measuring the degree of bending in a bent glass sheet. The measuring is effected by cameras having a common imaging field within the boundaries of a surface being measured. The cameras are set at an arbitrary but stationary angle relative to each other. The glass surface along a profile to be measured is made visible to the cameras by an illuminating line whose light has a high intensity over the wavelength ranges of 250-330 nm. Hence, an extremely thin film of tin, left on the glass surface in the manufacture thereof, becomes visible.
