Abstract

A method of improving the interference resistance of multi-color barcodes is pro-posed, which is based on the application of two-level control of errors that occur when scanning a multi-color barcode image, using two multi-valued correcting codes: the BCH code - at the level of barcode patterns (lower level), and the Reed-Solomon code - at barcode symbol level (top level). The proposed method makes it possible to create multi-color barcodes with im-proved immunity characteristics, which ensure reliable reproduction of data during scanning of large-capacity multi-color barcode images in automatic identification sys-tems.
