Chambard Jean Pierre, Chalvidan Vincent: Method and device for measuring at least a geometric quantity of an optically reflecting surface. Holo 3 Ass Pour Le Dev Des Met, June 23, 2004: EP1430271-A1

Method for measuring a geometric value of a optically reflective surface using a camera (2), whereby calibration is carried out prior to measurement so that quantitative output values for the geometric value can be obtained. The calibration is carried out using a reference surface. An Independent cl ...
