Embodiment 1

[0059] figure 1 It is a flow chart of the image mosaic method provided by Embodiment 1 of the present invention. The technical solution of this embodiment is applicable to the situation where two or more images are stitched into one panoramic image, for example, when multiple two-dimensional medical images are stitched into one medical image to facilitate diagnosis and treatment by doctors. In this embodiment, the two Let's take a DR image spliced ​​into one DR image as an example. The method can be executed by the image splicing device provided in the embodiment of the present invention, and the device can be implemented in the form of software and / or hardware, and configured to be applied in a processor. like figure 1 As shown, the method includes the following steps:

[0060] S101. Acquire a reference feature point of a reference image and a search feature point of a search image corresponding to the reference feature point based on preliminary registration accuracy.

Embodiment 2

[0098] Figure 7 It is a structural block diagram of the image stitching device provided by Embodiment 2 of the present invention. The device is used to execute the image mosaic method provided in any of the above embodiments, and the device may be implemented by software or hardware. like Figure 7 As shown, the device includes:

[0099] The feature point acquisition module 11 is used to acquire the reference feature point of the reference image and the search feature point of the search image corresponding to the reference feature point based on the preliminary registration accuracy;

[0100] The search feature point update module 12 is configured to determine the position of the interpolation point with the greatest similarity to the reference feature point within the neighborhood of the search feature point based on the preset registration accuracy, so as to update the search feature point , wherein the preset registration accuracy is higher than the preliminary registr...

Embodiment 3

[0106] Figure 8 The structural block diagram of the computer equipment provided for the third embodiment of the present invention, such as Figure 8 As shown, the device includes a processor 201, a memory 202, an input device 203, and an output device 204; the number of processors 201 in the device may be one or more, Figure 8 Take a processor 201 as an example; the processor 201, memory 202, input device 203, and output device 204 in the device can be connected by bus or other methods, Figure 8 Take connection via bus as an example.

Abstract

The embodiment of the present invention discloses an image mosaic method, device, computer equipment and storage medium. The method includes: based on the preliminary registration accuracy, acquiring the reference feature points of the reference image, and the search features of the search image corresponding to the reference feature points point; based on the preset registration accuracy, within the neighborhood of the search feature point, determine the position of the interpolation point with the greatest similarity to the reference feature point to update the search feature point, wherein the preset registration accuracy is higher than the preliminary registration Accuracy; according to the correspondence between the reference feature points and the updated search feature points, the reference image and the feature image are registered to generate a registration image; the stitching in the registration image is eliminated by image fusion to generate a stitching image. It solves the problem that the prior art cannot give consideration to both the image splicing effect and the splicing speed, and achieves the technical effect of not only ensuring the image splicing effect, but also improving the image splicing speed.

Description

technical field [0001] Embodiments of the present invention relate to the field of image processing, and in particular, to an image splicing method, device, computer equipment, and storage medium. Background technique [0002] Image stitching refers to the process of splicing two or more overlapping images describing the same scene into a new image of a large scene through image registration and image fusion technology. With the increasing demand for image analysis, more and more fields need to obtain panoramic images through image stitching, such as medicine, remote sensing technology and virtual reality and other fields. [0003] The image stitching accuracy of the prior art includes pixel level and sub-pixel level. The former has a small amount of calculation and faster image stitching, but the registration accuracy of the stitched image is lower; although the registration accuracy of the latter stitched image is higher, However, the amount of calculation is large and th...
