Title:
METHOD, SYSTEM AND PANORAMIC DEVICE FOR RESOLVING COLOR CHANGES IN IMAGE STITCHING
Document Type and Number:
WIPO Patent Application WO/2017/080179
Kind Code:
A1
Abstract:
The present invention discloses a method, system and panoramic device for resolving color changes in image stitching, the method being suitable for a panoramic device comprising N imaging devices, and comprising: performing quantitative processing on an electrical signal acquired by each imaging device, and forming each image to be stitched of a panoramic image; calculating an amount of deviation of stitching regions of neighboring images to be stitched; and performing gain adjustment on each image to be stitched, so as to bring the deviation of the stitching region of the neighboring images to be stitched to within a preset range. The technical solution of the present invention, can basically maintain consistency in output brightness and chromaticity of stitching regions of all neighboring images to be stitched, resolving the problem of ineffectiveness in adjusting brightness and chromaticity using an image processing algorithm, and problems of excessive resource consumption and poor processing efficiency.
