A method, a system, and a computer program product for object color correction are provided. Two images of the same target provided by two image capturing devices are introduced into an image conversion model constructed by an image conversion algorithm, and a color coefficient and a luminance coefficient for color space conversion are found, so as to convert the two images to a target color space. Then, the two images in the target color space are introduced into an image color distribution space model constructed by the image conversion algorithm, so as to obtain two different image color distribution space principal axes. The two image color distribution space principal axes are compared and adjusted to be parallel, thereby adjusting a color difference between the two images. The two images that are adjusted are converted back to an original color space, so as to obtain the two corrected images.
