Abstract : The patent application concerns a system for automatically measuring the positions of reseau grid lines and other calibration marks on photographs, using a digital computer to control a non-coherent optical correlator. A digital control computer generates scanning motion of an input photograph containing reseaus and a non-coherent optical correlator computes a cross correlation function of the input photograph with a reference image.
