The invention discloses a multi-focus image fusion method based on a novel intuitionistic fuzzy similarity measurement technology. The multi-focus image fusion method comprises the steps of obtainingan image membership degree according to a type I fuzzy set theory; obtaining an upper membership degree and a lower membership degree of an interval type-2 fuzzy set of the image according to calculation; obtaining the membership degree, the non-membership degree and the hesitance degree of the intuitionistic fuzzy set of the image according to calculation; calculating the local similarity of theimage according to the membership degree, the non-membership degree and the hesitation degree of the intuitionistic fuzzy set of the image; obtaining a fusion decision diagram corresponding to the source image according to a local image fusion rule; aiming at the defects of the primary decision diagram, optimizing the primary decision diagram by utilizing hole filling based on image morphology processing; enhancing the ima
