The paper not only proposed the latest Two-Dimensional Barcodes Image-processing Module, but also captured the smallest camera screens (320x240) with different focal distances and tried to find out "Finder Pattern" for positioning images. Further, use CROBU (Conversion Ratio Of Basic Unit) the paper proposed to convert 2-D barcodes into 1-pixel ratio to match images before judging recognition rate of 2-D barcodes through matching. Normally speaking, 2-D barcodes are deciphered and recognized by software while the paper recognizes 2-D barcodes and enhances implementation speed up to 10-cm accurate max using image matching.
