METHOD AND DEVICE FOR DETERMINING GEOMETRIC TRANSFORMATION RELATIONSHIP BETWEEN IMAGES

WIPO Patent Application WO/2020/052068

A1

A method and device for determining a geometric transformation relationship between images. The method comprises: acquiring a first image, and a second image set comprising at least two second images; generating a target matrix according to coordinates of three non-collinear pixel points in the acquired first image; for the second images in the second image set, acquiring coordinates of the pixel points, corresponding to pixel points indicated by coordinates in a coordinate set, in the second images to obtain a corresponding coordinate set; generating, according to the corresponding coordinate set, a target column vector matching the number of columns of the target matrix; pre-multiplying the target matrix by the target column vector to obtain a transformed column vector; and determining, according to the transformed column vector, a geometric transformation relationship between the first image and the second images. In the method, in a scenario where a first image corresponds to a plurality of second images, the target matrix is generated in advance to accelerate the computation speed of solving a geometric transformation relationship between the first image and each second image.
