Abstract

The embodiment of the invention discloses a method for processing matched pairs of characteristic points of images. The method comprises the following steps of: extracting the characteristic points of the images to be matched and acquiring invariables of the characteristic points; extracting significant areas of the images to be matched and acquiring the matched pairs of the significant areas among the images to be matched; and according to the invariables of the characteristic points, acquiring the matched pairs of the characteristic points among the matched pairs of the significant areas as the matched pairs of the characteristic points among the images to be matched. The embodiment of the invention also provides an image retrieval method and image retrieval equipment. In the embodiment of the invention, a space constraint relationship among the characteristic points, namely the significant areas where the characteristic points are positioned, is fully utilized, so the error matching rate of the matched pairs of the characteristic points can be reduced, and the acquisition accuracy of the matched pairs of the characteristic points is improved.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to an image feature point matching pair processing, image retrieval method and equipment. Background technique

[0002] In the field of image processing, it is often necessary to obtain the feature point A that matches the feature point B of the image to be matched 2 from the image to be matched 1, and the feature point A and the feature point B are called the features of the image to be matched 1 and the image to be matched 2 Points match pairs. After the feature point matching pair is obtained, applications such as image matching and image retrieval can be performed based on the feature point matching pair.

[0003] The current feature point matching pair acquisition method includes the following steps: extracting the feature points of the image to be matched and obtaining the invariant of the feature point; for each feature point j of the image to be matched 1, according ...
