System and Method for Encoding and Decoding Large Capacity 2-Dimensional Color Bar Code Which Can Be Color-Corrected |
摘要 |
Disclosed herein are a bar code encoding system and a bar code decoding system. The bar code encoding system includes a method for compressing the original data and adding data for error detection and correction to the compressed data to generate a large capacity 2-dimensional color bar code so as to be used as prints in an off-line environment and a large capacity 2-dimensional bar code pattern. The decoding system includes a method for receiving the prints including the 2-dimensional bar code generated by the encoding system through an input device such as a scanner and a camera, searching the 2-dimensional bar code to recognize it, performing color correction and error detection and correction, decompressing the compressed data to decode the original data.
