Image feature point matching method, apparatus and device, and storage medium

Abstract

The invention discloses an image feature point matching method, which comprises the steps of determining a homography matrix between a target image and an original image through a one-to-one correspondence relationship between auxiliary point projection coordinates which can be distinguished from each other in the target image and auxiliary point coordinates in the original image; and according tothe homography matrix and the coordinates of the feature points in the original image, determining a one-to-one correspondence matching relationship between the projections of the feature points in the original image and the projections of the feature points in the target image. An original image adopted by the image feature point matching method comprises feature points used for matching and a plurality of auxiliary points capable of being distinguished from one another. According to the image feature point matching method, the rough corresponding relation between the original image and thetarget image is obtained, and high-precision matching of the feature points in the original image and the target image is determined based on the rough corresponding relation, and operation is easy and feasible while too complex operation is not needed, and development and application of the visual technology are facilitated. The invention further provides an image feature point matching apparatusand device and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device, equipment and computer-readable storage medium for matching image feature points. Background technique [0002] The matching of feature points in the image refers to the one-to-one correspondence between the feature points in the new image and the feature points in the original image after translation, rotation, affine or projection of the original image. Image feature point matching is widely used in visual image technology, such as camera calibration, robot pose determination, keystone correction of projected images, and so on. [0003] The current matching methods of image feature points often have problems such as low accuracy of matching results, poor anti-interference performance and complicated matching process. Contents of the invention [0004] The purpose of the present invention is to provide a matching method, device, equipment an...
