Title:
HIGH-RESOLUTION IMAGE MATCHING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/000471
Kind Code:
A1
Abstract:
A high-resolution image matching method and system. The method comprises: performing regional fidelity downsampling on an initial high-resolution image, and obtaining a multi-level low-resolution image; performing local matching on the obtained multi-level low-resolution image by adopting a mode having a global probe to obtain a matching result of the low-resolution image; utilizing the overall consistency of image matching to perform reverse refinement on the obtained matching result of the low-resolution image to obtain the matching result of each level of high-resolution image until the matching result of the initial-resolution image is obtained. Therefore, the calculation amount of an image matching process can be reduced, the precision of the matching result can be improved, and the matching result of the high-resolution image is obtained by means of reverse refinement on the basis of the overall consistency.
