Abstract

A kind of automatic matching system for planar pattern points which includes: (1) coarse matching: provide the least satisfied conditions when matching any point in one pattern and any point in another pattern so as to filter out the impossible matched points in the two patterns and to save the calculation time; (2) calculating the matching probability: employing the fuzzy relaxation to calculate the matching probability for all the points in one pattern and all the points in another pattern; (3) selecting the matched points: selecting the most possible matched points in the two patterns according to the matching probability of all the points of the two patterns; (4) calculating the approximation level between two patterns: calculating the approximation index between two patterns; (5) judging whether two patterns are approximate: deciding whether two patterns are approximate according to a default boundary value. The invention also includes to find out the best geometric adjusting value according to the matching result after primary matching in order to adjust the test patterns for accurate identification result. The invention also provides a novel fuzzy relaxation in calculating matching probability.
