Abstract:
1. A barcode recognition method, used to recognize values of a plurality of barcode data of a plurality of barcode patterns, wherein the barcode patterns are located in a barcode image and the barcode recognition method comprises: providing a plurality of barcode template images, wherein the barcode template image comprises a plurality of barcode template patterns, and the barcode template patterns having a plurality of blank area patterns, and positions of the blank area patterns are different from each other to enable the barcode template patterns correspond to a plurality of different barcode alignment modes in a one to one manner, and each of the barcode template patterns has a plurality of data boundary patterns and at least one data space template patterns; performing a foreground extraction step for extracting a foreground image from the barcode image, wherein the foreground extraction step performs a binarization process on the barcode image; performing a pre-alignment processing step comprising: performing an alignment step, comprising: performing a barcode value recognition step for recognizing values of the target binary barcode pattern in accordance with patterns in the value data areas.
