Title:
IMAGE REGISTRATION METHOD AND APPARATUS, STORAGE MEDIUM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/169281
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are an image registration method and apparatus, a storage medium and an electronic device. In one embodiment of the present application, the method comprises: first acquiring a reference image and an image to be registered; by means of an optical flow method, determining matching control point pairs in the reference image and the image to be registered; further on the basis of the control point pairs, using a thin plate spline interpolation method to obtain a first mapping relationship between the reference image and the image to be registered; and on the basis of the first mapping relationship, registering to the reference image the image to be registered. In the embodiment of the present application, the optical flow method and the thin plate spline interpolation method are combined; uniformly and widely distributed control points can be acquired by means of the optical flow method, and smooth mapping is obtained on the basis of said control points by means of the thin plate spline interpolation method, so that while image registration is realized, deformation of an image is reduced and the accuracy of image registration is improved.
