Abstract: Image match is an extremely important technology in the applications of target detecting，target identification and tracking.There are many image matching methods，now the available method adopts the ergodic dyadic search strategy without exception，the lessening calculating quantity’s as a result is limited，if not adopt the new search strategies，the breakthrough being difficult to get a substantiality on the lessening calculating quantity’s，this is the common faults of the image match algorithms.This paper uses the evolutionary algorithm into the match technology，uses the characteristics of the relevance match such as calculation simplicity，the anti-noise function well，and proposes an image match method base on the evolutionary algorithm.The experiment results indicate that the method has the characteristics such as the high speed calculation，correct matching rate height and anti-noise function regards.
