Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0017] refer to figure 2 , the invention provides a kind of image registration method, and this method comprises the following steps:

[0018] Step 1. Preliminary matching: use common feature detection and descriptors such as corner points or local invariant regions, and use Euclidean distance as a measure to perform preliminary matching to obtain a matching set. The closest distance between the vectors (ie, feature point pairs) in the two images is the best...

Abstract

The invention discloses an image registration method, which relates to the technical field of computer image processing. The method mainly comprises the steps of: carrying out the preliminary matching, manufacturing a sample subset, building a reliable set, calculating a model, completing the iteration for a certain number of times, and obtaining a final mode. Thus, the purpose of efficiently andreliably eliminating a matching error in an image registration process can be realized.

Description

technical field [0001] The invention relates to the technical field of computer image processing, in particular to an image registration method. Background technique [0002] Image registration can realize image fusion, information retrieval, depth perception and 3D reconstruction, etc., and is widely used in computer vision, remote sensing data analysis, biomedical detection, military target recognition and other fields. [0003] In the process of image registration based on computer vision, due to the existence of symmetry and similarity features in the image, it is easy to cause ambiguity in the positioning and matching of each scene, and even cause matching failure, such as figure 1 shown. Contents of the invention [0004] The embodiment of the present invention provides an image registration method, which can solve the problems existing in the prior art. [0005] The present invention provides a kind of image registration method, described method comprises the foll...
