1. A method for performing an optimization process on a two-dimension code picture, comprising: performing a color filtering process on an obtained two-dimension code picture, obtaining a color-filtered two-dimension code picture; performing a median filtering process on the color-filtered two-dimension code picture, obtaining a median-filtered two-dimension code picture; performing a binarization process on the median-filtered two-dimension code picture, obtaining a binary image, and utilizing the binary image to effectively identify a two-dimension code in the two-dimension code picture; wherein performing the color filtering process on the obtained two-dimension code picture, and obtaining the color-filtered two-dimension code picture, comprise: obtaining an original color value of a pixel point in the two-dimension code picture; and performing a color filtering conversion on the original color value of the pixel point in the two-dimension code picture, and obtaining a color value of the color-filtered pixel point in the two-dimension code picture, wherein the color value of the color-filtered pixel point in the two-dimension code picture forms the color-filtered two-dimension code picture.
