Abstract
A system and method of point matching measured positions to template, or reference, positions for various applications may generally comprise creating force field vectors and moments operative to perturb measured point locations into alignment with template point locations. Progressive reduction of the force radius may produce results that match very well for points that are highly correlated with the template pattern.
