Abstract
This paper mainly introduces the structure and encoding principle of PDF417 two-dimensional barcode, and gives encoding algorithms such as data code-word encoding, error correction code-word encoding and symbol code-word encoding. Finally, the barcode pictures are generated through experiments.
