Abstract
A method of and system for compensating for geometric distortion in a two-dimensional image finds fiducial marks in the image plane corresponding to fiducial marks in the object plane. The invention includes performing a matched filter search to locate corner fiducials from an object plane in the image plane. Locating the corner fiducials permits locating the remaining fiducials in the image plane. A centroid calculation makes the location of the fiducials in the image plane more precise and permits the generation of a solution matrix. The solution matrix and a trajectory engine map the pixels in the image plane to compensate for magnification, tilt, pin cushion, barrel, and other types of geometric distortions.
