1. A method for object color correction, comprising: obtaining a first image of a first image capturing device and a second image of a second image capturing device; constructing an image conversion model and an image color distribution space model according to an image conversion algorithm; introducing the first image and the second image into the image conversion model, and calculating a target image color coefficient and a target image luminance coefficient for converting the first image and the second image from an original color space to a target color space by using the image conversion algorithm; converting the first image and the second image from the original color space to the target color space according to the target image color coefficient and the target image luminance coefficient; respectively introducing the first image and the second image in the target color space into the image color distribution space model, so as to obtain a first image color distribution space principal axis and a second image color distribution space principal axis respectively; comparing the first image color distribution space principal axis and the second image color distribution space principal axis, and correcting them by a processing unit so that the first image color distribution space principal axis and the second image color distribution space principal axis are parallel to each other, so as to adjust a color difference between the first image and the second image; reintroducing the first image and the second image in the target color space into the image conversion model, so as to convert the first image and the second image from the target color space to the original color space; and obtaining the corrected first image and the corrected second image.
