Title:
IMAGE REGISTRATION METHOD AND RELATED MODEL TRAINING METHOD, DEVICE AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/238171
Kind Code:
A1
Abstract:
An image registration method and a related model training method, device and apparatus. The method comprises: acquiring a real two-dimensional image and a reference two-dimensional image (S10); performing feature extraction on the reference two-dimensional image by using a virtual image feature extraction network of an image registration model to obtain a first virtual feature map, wherein the image registration model is pre-trained using a virtual image, the virtual image feature extraction network participates in pre-training, and the virtual image is generated on the basis of a virtual target (S11); performing feature extraction on the real two-dimensional image by using a real image feature extraction network of the image registration model to obtain a first real feature map, wherein the real image feature extraction network does not participate in the pre-training (S12); and adjusting network parameters of the real image feature extraction network by using the difference between the first real feature map and the first virtual feature map (S13).
