Abstract
A color correction method for a panoramic image comprises: acquiring a first and second fisheye images; expanding the first fisheye image and the second fisheye image respectively to obtain a first image and a second image in an RGB color space; calculating overlapping areas between the images; converting the first image and the second image from the RGB color space to a Lab color space; in the Lab color space, adjusting the brightness value of the first image and the brightness value of the second image; converting the first image and the second image from the Lab color space to the RGB color space; according to the mean color values of a first and second overlapping areas, adjusting the color value of the second image by using the first image as a reference, or adjusting the color value of the first image by using the second image as a reference.
