Research And Application Of Two-Dimension Barcode Technology Of Mobile Phone

This paper mainly combines the encoding and decoding technology of the two-dimension barcode and related technology of intelligent mobile phone. Based on technology of two-dimension barcode and intelligent mobile phone, the method of generating and recogniting two-dimension barcode on series 60 platform is proposed in this paper.For the generating method on s60 platform, some properties of the Symbian OS and S60 and their exploration in the application field is studied in this paper. Then with the study of graphic drawing on S60 platform and the structure of the Data Matrix two-dimension barcode, the function of drawing two-dimension barcode is implemented on the S60 mobile phone platform.For the identification method on the platform of the intelligent mobile phone, the usual method is studied in this paper. Especially for image taken by mobile phone camera in close distance, many problems that will disturb the recognition for two-dimension barcode arise, such as skew, distortion and so on. So several things should be done. First, several pre-processing, such as ostu binary processing should be done. Second, the algorithm of polygonconvexhull in Geometrics is used in fixing the area where the two-dimension barcode should be. Third, the projection transformation algorithm to correct the barcode image is used. The above image processing can well remove these flaws and make it more clear and more easily to be recognized.Finally, the encoding and decoding system of the two-dimension barcode is constructed on the intelligent mobile phone S60 platform in Symbian OS, which can make the two-dimension barcode and recognize its image taking by intelligent mobile phone.
