Method based on conversion scanning between one-dimensional code and two-dimensional code

Abstract

The invention discloses a method based on conversion scanning between a one-dimensional code and a two-dimensional code. The method comprises the following steps: circularly identifying a decoding request; starting any scanning module to scan, search and compare distinguishing feature points of image article codes, and judging the category attributes of the article codes according to the distinguishing feature points of the image article codes; and judging whether the image article codes corresponds to the started scanning module or not according to the category attribute of the article codes,and if the scanning fails, judging that the article codes do not correspond to the started scanning module, automatically skipping to another scanning module for scanning identification to finish scanning identification. The category attributes of the article codes are quickly identified by comparing the distinguishing feature points of the image article codes; whether the category attributes ofthe article codes correspond to the started scanning module or not is accurately judged, automatic selection is performed without skipping to directly complete identification or skipping to another scanning module to perform scanning identification, manual judgment for selecting the scanning module to perform identification scanning is omitted, operation is convenient, and the identification speedis high.

Description

technical field [0001] The invention relates to the field of article code identification, in particular to a method based on conversion and scanning between one-dimensional codes and two-dimensional codes. Background technique [0002] Existing article codes are mainly divided into two-dimensional codes (such as QR Code, PDF417, DataMatrix and Chinese Sensible Code) and one-dimensional codes (such as barcodes). The two-dimensional code module is used to identify and scan two-dimensional codes or one-dimensional codes, one-dimensional The module is used to recognize one-dimensional codes. Most of the scanning modules used to scan item codes are installed on various hand-held scanners or scanning platforms, and obtain corresponding item information or payment information by scanning and identifying graphic barcode marks. Because the length of the one-dimensional code (barcode) is long, and the recognition area of ​​the two-dimensional code module is small, it is impossible to...

AI Technical Summary

Problems solved by technology

Because the length of the one-dimensional code (barcode) is long, and the recognition area of ​​the two-dimensional code module is small, it is impossible to scan the complete one-dimensional code (barcode), resulting in the failure of recognition. Multiple adjustments and scans are required, and the operation is complicated, and The recognition and interpretation speed of the two-dimensional code module is relatively slow, far inferior to the speed and accuracy of the recognition and interpretation of the one-dimensional module

[0003] In the field of current scanning methods, different systems need to be installed on two devices to complete the scanning of QR codes and 1D codes respectively, which will be inconvenient to carry, and the number of back-end devices will also increase, making it inconvenient to use

An existing scanning method is to combine the one-dimensional module and the two-dimensional module in the same device. This method requires the support of two systems at the same time, and requires manual identification of the type of item code, and switches through buttons to run different systems to scan. , this method is complex in operation and slow in recognition speed
