    A fast PDF417 decoding terminal is designed and implemented based on DSP platform. This terminal collects images of PDF417 barcode by camera and is able to extract bareode regions from complex background, correct bareode deformation and etc. The designed device, even under unbalancing illumination or complex background, can decode PDF417 in a high speed regardless of the orientation of the barcode.
