Abstract
A method for determining geometric transformation relation for images is provided. The method includes: obtaining a first image and a second image collection; obtaining coordinates of three non-collinear pixels in the first image to forma coordinate collection; generating a target matrix according to the coordinate collection, and for the at least two second images in the second image collection, obtaining coordinates of pixels in the at least two second images corresponding to coordinate-indicative pixels in the coordinate collection to form a corresponding coordinate collection; according to the corresponding coordinate collection, generating a target column vector matching a column number of the target matrix; pre-multiplying the target matrix by the target column vector to obtain a transformation column vector; determining the geometric transformation relation of the first images and the at least two second images according to the transformation column vector.
