The present application relates to an image registration method, comprising: selecting a registration source image {p,} and a registration target image {qj}; applying a random perturbation to {pi} in accordance with a preset random perturbation control parameter sigma so that it is deformed to obtain {pi'}, and obtaining a set of closest points, i.e., {qj'}, on {qj} corresponding to points on {pi'}; performing an iterative operation on {pi} and {qj'} in accordance with a preset initial coordinate transformation H0 to obtain a coordinate transformation {Hl}, 0<l<L, between {pi'} and {qj'}, and calculating an average distance {El} corresponding to the coordinate transformation {Hl} in accordance with the coordinate transformation {Hl}; judging magnitudes of the average distance {El} and a preset ideal average distance Ex, and terminating the registration when the average distance {El} is smaller than or equal to the preset ideal average distance. |
