Image registration method, computer program product, storage medium and electronic device

The invention relates to the technical field of image processing, and provides an image registration method, a computer program product, a storage medium and electronic equipment. The image registration method comprises the following steps: acquiring a reference image and an intermediate image; taking the image registration reference image as a benchmark, calculating a homography matrix between the image registration intermediate image and the image registration reference image by using a registration algorithm based on the homography matrix, and calculating a homography optical flow corresponding to the image registration homography matrix; calculating a forward optical flow between the image registration intermediate image and the image registration reference image by using an optical flow-based registration algorithm on the basis of the image registration reference image; fusing the image registration homography optical flow and the image registration forward optical flow to obtain a fused optical flow; an
