Abstract

The object of the invention is to provide an image registration method and image registration equipment. The image registration method comprises steps that characteristic points of acquired annularly-arranged to-be-registered images are calculated; an initial relative offset vector between each two adjacent images of the annularly-arranged images is determined according to the characteristic points of the annularly-arranged to-be-registered images; the relative rotation angles of the annularly-arranged to-be-registered images and the relative offset vectors of the annularly-arranged to-be-registered images after being rotated by the above mentioned angles are determined according to the initial relative offset vectors. By introducing a priori model of image annular arrangement, the characteristic points of the various images of the model are calculated, and the initial relative offset vector between each two adjacent images of the annularly-arranged images is determined, and then the relative rotation angles of the annularly-arranged images are calculated by using the model information of the image annular arrangement in an actual condition and the initial relative offset vector between each two adjacent images of the annularly-arranged images, and therefore result errors are reduced after image registration.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and device for image registration. Background technique [0002] Image registration is the process of mapping a point in one image to some spatial variation of the same point on the same object in another image. The current image registration is divided into two methods: calculating the translation or calculating the single mapping matrix. The calculation of the translation method is simple and cannot handle the rotation between images. The calculation of the single mapping matrix method requires a large amount of calculations and requires image feature matching results. Higher, the correct result can only be obtained when the accuracy of the matching result is higher. The current method is mainly to calculate the homography matrix based on the random sampling consensus algorithm (RANSAC) based on the feature points. In the quasi-model case, no relevant model informa...
