Field of view fusion method and device, storage medium, and terminal

Abstract

A field of view fusion method and device, storage medium, and terminal, the method comprising: determining a wide-angle image and a telephoto image; and performing feature point matching on the wide-angle image and the telephoto image based on the scale of the wide-angle image , and generate a feature point pair; determine the image to be fused according to the feature point pair, the image to be fused includes a feature point distribution area and a feature point distribution area; determine a plurality of first mappings of the feature point distribution area matrix, and obtain the first resampled image; determine the mapping matrix of each pixel in the non-feature point distribution area, and obtain the second resampled image; superimpose the first resampled image and the second resampled image Processing to obtain the overall resampled image of the telephoto image; and performing fusion processing on the overall resampled image of the telephoto image and the wide-angle image by using preset weights to obtain a fusion image of the field of view. The solution of the invention can improve the accuracy of the mapping matrix.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a field of view fusion method and device, a storage medium and a terminal. Background technique [0002] Camera technology plays an increasingly important role in smartphones. Small size and large zoom range of cameras are two important functions of current mobile phone cameras. Using optical lenses to achieve optical zoom, although high-quality zoom images can be obtained, it will inevitably increase the size of the camera, and the cost will be greatly increased; while the ordinary single-camera digital zoom, although it can ensure the size of the camera and control the lower cost, However, the image quality after zooming is not satisfactory. Therefore, the technology of using multiple cameras with different focal lengths to simulate the realization of optical zoom came into being. At present, the more common combinations are: [0003] a Combination: a dual-focu...

AI Technical Summary

Problems solved by technology

[0008] In a prior art, the camera is directly switched to realize the field of view fusion of the wide-angle and telephoto images, but it is easy to produce a visual jump at the zoom switching point of the two cameras, giving the user an unnatural experience

[0009] In another prior art, an image processing technology is adopted, and a global homography matrix is ​​adopted for mapping to realize the field of view fusion of wide-angle and telephoto images. At strong textures, there is obvious misalignment, which reduces user experience
