| Zusammenfassung: | An apparatus and method for generating a two-dimensional (2D) barcode and an apparatus for extracting 2D barcode information. The apparatus for generating a 2D barcode includes a metadata creation unit for creating metadata corresponding to insertion data and a 2D barcode, a data conversion unit for generating data blocks by converting the insertion data based on the metadata, a pattern generation unit for generating metadata patterns and data block patterns by substituting respective predefined symbols for the metadata and the data blocks, and a 2D barcode generation unit for generating a 2D barcode that contains distortion correction patterns, the metadata patterns, and the data block patterns. |
