Original image color adjustment method and device for panorama camera

Abstract

The invention discloses an original image color adjustment method and device for a panorama camera. The method comprises the steps: obtaining a superposed area of a first original image and a second original image, which are collected by the panorama camera; detecting and obtaining feature points of the superposed area of the first and second original images, and describing the feature points through descriptors; carrying out the matching of the feature points of the first and second original images according to the descriptors of the feature points, and obtaining a plurality of groups of matched feature points; selecting one of the first and second original images as a reference image, selecting the other original image as a to-be-adjusted image, and obtaining a color adjustment parameteraccording to a YUV value of each group of matched feature points; and adjusting the color of the to-be-adjusted image according to the color adjustment parameter. Therefore, before the splicing of the original images of the panorama camera into a panorama image, the method achieves the adjustment of the colors of the original images, and improves the fusion effect of the panorama image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for adjusting the color of an original image of a panoramic camera. Background technique [0002] The panoramic camera uses at least two or more lenses to shoot the space scene at the same time to obtain two or more original images, and then stitches the two or more images after shooting into a 360° panoramic image. [0003] Due to the manufacturing defects and lighting effects of each lens in the panoramic camera, there are differences in color between different lenses. When the colors of two or more original images obtained by shooting are different, it will directly affect the subsequent image fusion effect. As a result, there is a color consistency problem in the panoramic image output by the panoramic camera. When the color difference of two or more images is too large, good results cannot be obtained through the subsequent fusion algorithm, and...
