Color correction and restoration system and color correction and restoration method

The invention discloses a color correction and restoration method and system. The color correction and restoration method includes: Step A: sequentially shooting a plurality of pieces of color card paper having different colors and placed in a correction and restoration area; Step B: calculating a scaling factor of color card shooting RGB values of each of the plurality of pieces color card paper pictures in each pixel position in a correction and restoration area and standard RGB values of the color card paper, generating a scaling factor table according to calculation results and storing the scaling factor table and the corresponding color card paper pictures in a storage in an associated manner; Step C: shooting an object placed in the correction and restoration area; and Step D: calculating object shooting RGB values of a picture of the object in each pixel position in the correction and restoration area, and performing correction and restoration on the picture of the object according to the plurality of color card paper pictures and the associated scaling factor table in the storage. The color correction and restoration method and system is accurate in correction, and can improve the accuracy of a color classification system.
