2D coding and decoding barcode and its method thereof |
摘要 |
A two-dimensional barcode includes a plurality of macro modules arranged in a two-dimensional array in a spiral sequence, each of macro modules includes a predetermined number of data unit modules for storing data codewords of a predetermined binary stream of bits, a predetermined number of cluster unit modules for storing a predetermined cluster number representing a location of the macro module, and a predetermined number of rim unit modules which possess a predetermined color to form a rim of the macro module. The rim unit modules of two adjacent macro modules are contrasting with each other to enhance identification of the respective macro module.
