Method and system for overcoming abrupt color change in image fusion processes

Abstract

The invention discloses a method and system for overcoming abrupt color change in image fusion processes and a panorama device. The method is suitable for the panorama device comprising N imaging apparatuses and comprises the following steps: electric image signals collected by all image apparatuses are subjected to quantification operation, all images to be fused of a panorama image are formed, deviation amounts of fusion zones of adjacent images to be fused are calculated, all the images to be fused are subjected to gain adjustment operation, and the deviation amounts of the fusion zones of the adjacent images to be fused are enabled to be in a preset scope. Via use of a technical solution provided of the method and system for overcoming abrupt color change in image fusion processes, all fusion zones of the adjacent images to be fused can be enabled to be basically same in output brightness and chromaticity; problems of effectiveness, excessive resource consumption and processing efficiency caused by brightness and chromaticity adjustment realized via an image processing algorithm can be overcome.

Description

technical field [0001] The invention relates to the technical field of image splicing, in particular to a method and system for overcoming color mutation in image fusion. Background technique [0002] Image mosaic technology is the technology of stitching several images with overlapping parts into a panorama, in which the several images with overlapping parts are imaging under different viewing angles. [0003] The imaging under different viewing angles is simultaneously obtained by multiple (two or more) imaging devices (such as cameras). Typical applications of this type of image stitching technology are multi-camera stitching panoramic cameras, panoramic parking, etc. . As one of the key technologies of image stitching, image fusion is to superimpose the overlapping areas of the fields of view of the images to be fused, that is, the fusion area, to obtain a stitched and reconstructed seamless panoramic image. However, from the aforementioned introduction to the image st...

AI Technical Summary

Problems solved by technology

[0005] 1. It is difficult to solve the problem of brightness and chromaticity differences between images to be fused from the root cause, and will be inherently affected by the effectiveness of image processing algorithms;

[0006] 2. The image processing algorithm is usually relatively complex, which will cause a large consumption of system application resources; and as the image resolution increases, the consumption will also increase sharply;

[0007] 3. The consumption of system application resources leads to a decrease in processing efficiency
