Two-dimensional bar code scanning method and system

Abstract

Provided is a two-dimensional bar code scanning method and system. The two-dimensional bar code scanning method includes steps of: starting: creating a text file, starting an image collection device, activating a timer and setting interval time for the timer; acquiring: when the timer triggers the image collection device to automatically collect two-dimensional bar code pictures of products to be scanned, acquiring and storing the collected two-dimensional bar code pictures; decoding: processing the acquired two-dimensional bar code pictures and invoking a decoding function to decode the two-dimensional bar code pictures; judging: judging whether decoding is successful, and finishing once operation of the timer and returning to the acquiring step to re-collect the two-dimensional bar code pictures of the products to be scanned if decoding fails: and storing: when the decoding succeeds, storing decoding information of the two-dimensional bar code pictures in the text file created in the starting step. The two-dimensional bar code scanning method and system achieves automatic scanning of two-dimensional bar codes, and the automatic scanning replaces manual scanning.

Description

technical field [0001] The invention relates to a method and system for scanning two-dimensional barcodes. Background technique [0002] In the current production of various electronic products, in order to ensure that the products can be traced back to every link of production, each station of the production line must scan and upload the two-dimensional barcode of the product, which is equivalent to the identity certificate of the product , Traditionally, scanning guns are used for scanning, but the price of scanning guns is relatively expensive. According to the principle of coding and decoding of two-dimensional codes, we can understand that two-dimensional codes are actually composed of square or rectangular code elements composed of many small squares. Statistics are made through the color changes of small squares. The small black squares represent binary The small white square of "1" represents binary "0". There are already mature codes for two-dimensional code image ...

According to the principle of coding and decoding of two-dimensional codes, we can understand that two-dimensional codes are actually composed of square or rectangular code elements composed of many small squares. Statistics are made through the color changes of small squares. The small black squares represent binary The small white square of "1" represents binary "0". There are already mature codes for two-dimensional code image conversion on the Internet, but image acquisition still requires manual operation, which cannot meet the needs of factory automation operations.
