Embodiment 1

[0059] In order to facilitate the understanding of this embodiment, an image registration method disclosed in the embodiment of the present invention is first introduced in detail.

[0060] An image registration method disclosed in this embodiment is executed by a computing device. The computing device calculates the template vector of the registration region selected by the user from the template image and each image to be registered among the multiple images to be registered Determining deformation parameters of multiple images to be registered corresponding to the vectors to be registered, and performing an image registration operation according to the obtained deformation parameters.

[0061] The computing device can use any existing computer and server to perform the image registration operation, which will not be repeated here.

[0062] see figure 1 , the present embodiment provides an image registration method, including the following specific steps:

Abstract

The invention provides an image registration method and device, and the method comprises the steps: obtaining an image sequence, and determining a template image and a plurality of to-be-registered images from the image sequence; obtaining a registration region selected by a user from the template image; calculating a template vector of the registration region and to-be-registered vectors corresponding to the to-be-registered images; determining the deformation parameters of the to-be-registered images according to the template vector and the to-be-registered vectors corresponding to the to-be-registered images; and carrying out the image registration operation of the to-be-registered images according to the obtained deformation parameters. According to the embodiment of the invention, the method and device can reduce the operation time of image registration.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image registration method and device. Background technique [0002] At present, image registration technology is also called image stabilization technology. The purpose of image registration is to compare or fuse images of the same object under different conditions such as different acquisition devices, different times, and different shooting angles. Two images in a set of image data sets, by finding a method of spatial transformation, one of the two images is mapped to the other image, so that the points corresponding to the same spatial position in the two images are one by one Correspondingly, so as to achieve the purpose of information fusion. Image registration technology has a wide range of applications in image processing technology fields such as image and video stitching, medical image registration, target tracking, image super-resolution and face co...
