ABSTRACT:
A method for automatic matching of planar point patterns in a reference pattern with a test pattern includes course mating, calculation of a mated possibility for one point in each pattern, preliminary selection of mated pairs based on these possibilities, and calculation of a similarity value based upon the number of mated pairs, the mated rate of the reference and test patterns, and the average mating possibility and average distance between mated points.
