Embodiment Construction
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0029] Such as figure 1 as shown, figure 1 is a schematic diagram of the barcode image parallel processing architecture of the first embodiment of the present invention. In the first embodiment of the present invention, at least two processing units 101 and 102 are set in the barcode decoding device 100 . The processing units 101 and 102 are recognition units corresponding to different code systems, that is, the processing units 101 and 102 can respectively use recognition rules of different code systems to perform barcode recognition. For example, the processing unit 101 is a one-dimensional barcode recognition unit, and the processing unit 102 is a PDF417 barcode recognition unit. In addition, the barcode decoding device 100 can further be provided with a plurality of processing units to respectively correspond to the barcode recognition process ...
