Embodiment Construction

[0027] As mentioned in the background art, barcodes can be identified by barcode processing class library ZXing at present, specifically, barcodes in acquired images are detected, and then ZXing is used to decode the detected barcodes. However, this solution has the following disadvantages: a) This method requires a camera with autofocus and relatively high resolution to work properly; b) When the barcode is deformed, severely damaged, printed blurred, severely blocked, etc., it cannot be quickly Good recognition; c) When the captured barcode picture appears low light. Reflective, low resolution, can not be recognized well in the presence of noise, etc.; d) can recognize barcodes with certain rotation angles, but cannot recognize barcodes with arbitrary rotation angles.

[0028] To sum up, the traditional ZXing barcode recognition method cannot accurately scan codes in complex scenarios, and the usage scenarios are more limited.

[0029] In order to solve the above problems, ...

Abstract

The invention discloses a bar code recognition method and device, a storage medium and computer equipment, and the method comprises the steps: obtaining a target picture containing a to-be-recognized bar code; recognizing bar code characters in the target picture; calculating a target check code corresponding to the bar code character according to a check algorithm corresponding to the to-be-identified bar code; obtaining a reference check code corresponding to the bar code to be identified from the target picture, and comparing the target check code with the reference check code; and when the target check code is consistent with the reference check code, taking the bar code character as an identification result of the bar code to be identified. Through the method, bar codes in various complex scenes can be quickly and accurately scanned.

Description

technical field [0001] The invention relates to the field of computer equipment, in particular to a barcode identification method and device, a storage medium, and computer equipment. Background technique [0002] Today, the express logistics and transportation industry has achieved rapid development, and each express delivery list has a barcode (barcode). By scanning the barcode, the whereabouts of the courier during transportation can be recorded. At present, using a laser scanner or a camera to scan a barcode (barcode scanner) to identify the barcode can simplify the registration management of express delivery and improve the logistics speed. [0003] Traditionally, barcodes can be recognized by the barcode processing class library ZXing, wherein ZXing is an open source Java class library for parsing one-dimensional or two-dimensional barcodes in various formats. However, the traditional method of identifying barcodes through ZXing often cannot be applied to barcodes in...
