Abstract: In view of the problems of atlas matching for linkage
curves, a new method of transforming the general atlas-matching problem
into that of pattern recognition is proposed. The concept of
evolutionary pattern is introduced, the mode of evolutionary
identification is expounded, which is followed by the general
description, and the conversion relations as well as the correspondence
rules of parameters in different spaces are discussed. Finally, an
evolutionary approach to the identification of linkage curves is
proposed. Based on the feature extraction of linkage curves, the
evolutionary factors are operated by genetic algorithm, the relevant
information of linkage curve is searched in the atlas base according to
the results, and then the structure parameters of the linkage mechanism
corresponding to this curve can be obtained. The effectiveness of the
proposed method is verified by a practical instance, which provides a
new approach to the identification of linkage curves.
