Abstract

The invention relates to an image registration method and device, a model training method and device, equipment, a server and a medium. The method comprises the steps of obtaining a first image to be registered and a reference image to be registered, inputting the first image to be registered and the reference image to be registered into a trained offset prediction model, and obtaining an offset prediction value between the first image to be registered and the reference image to be registered, wherein the offset prediction model is obtained by training based on a sample image to be registered, a sample reference image and a standard offset between the sample image to be registered and the sample reference image, and registering a first image to be registered and the reference image to be registered according to an offset prediction value. By means of the technical scheme, the effect of the registration precision of the first image to be registered and the reference image to be registered is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of image processing, and in particular to an image registration and model training method, device, equipment, server and medium. Background technique [0002] Image registration is for different images of the same object acquired under different conditions. Through a series of operations, the spatial changes between the images are obtained, and one image is mapped to the other image according to the spatial changes, so that the same image in the two images The points of the position correspond to each other. [0003] In the related art, when different images are registered, the feature points on the images tend to drift, and image registration based on the drifted feature points will lead to inaccurate image registration. Contents of the invention [0004] In order to solve the above technical problems or at least partly solve the above technical problems, the present disclosure provides an image...
