View field fusion method and device, storage medium and terminal

Abstract

The invention discloses a view field fusion method and device, a storage medium and a terminal. The method comprises the following steps: determining a wide-angle image and a telephoto image; taking the scale of the wide-angle image as a reference, carrying out the feature point matching of the wide-angle image and the long-focus image, and generating a feature point pair; determining a to-be-fused image according to the feature point pair, wherein the to-be-fused image comprises a feature point distribution region and a feature point-free distribution region; determining a plurality of firstmapping matrixes of the feature point distribution area, and obtaining a first resampling image; determining a mapping matrix of each pixel of the feature-point-free distribution area, and obtaining asecond resampling image; superposing the first resampling image and the second resampling image to obtain a total resampling image of a long-focus image; and performing fusion processing on the totalresampling image of the long-focus image and the wide-angle image by adopting a preset weight to obtain a view field fusion image. According to the scheme, the accuracy of the mapping matrix can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a field of view fusion method and device, a storage medium, and a terminal. Background technique [0002] Camera technology is becoming more and more important in smart phones. The small size of the camera and the large zoom range are two important functions of the current mobile phone camera. Using an optical lens to achieve optical zoom, although high-quality zoom images can be obtained, will inevitably increase the size of the camera, and the cost will increase greatly; while the ordinary single-shot digital zoom can ensure the size of the camera and control the lower cost. However, the image quality after zooming is unsatisfactory. Therefore, the technology of using multi-camera simulation with different focal lengths to achieve optical zoom came into being. Currently, the more common combinations are: [0003] a Combination: a combination of a wide-angle camera a...

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
