Embodiment 2

[0059] In order to further improve the accuracy of the determined scaling ratio, thereby further achieving the effect of improving decoding accuracy, on the basis of the above embodiments, in the implementation of the present invention, when the identification characters include a start character and a stop character , according to the first ratio and the second ratio, determining the scaling of each decoded character in the barcode to be decoded includes:

[0060] determining a first sub-scale for each decoded character in the barcode to be decoded according to the first ratio of the initial character and the second ratio;

[0061] determining a second sub-scale for each decoded character in the barcode to be decoded based on the first ratio of the terminating character and said second ratio;

[0062] According to the first sub-scaling ratio and the second sub-scaling ratio, the scaling ratio of each decoded character in the barcode to be decoded is determined.

[0063] In t...

Embodiment 3

[0079] When adjusting the bar width and the space width in the decoded characters, it can be to only adjust the bar width, or only to adjust the space width. In order to make the adjusted bar width and the space width in each decoded character more accurate, further To achieve the effect of improving the accuracy of decoding, on the basis of the above embodiments, in the embodiment of the present invention, the bar width or space width in each decoded character is adjusted according to the scaling ratio, and the Each decoded character after adjusting the bar width or empty width to decode includes:

[0080] identifying the space width or bar width of each decoded character, and adjusting the space width or bar width according to the scaling;

[0081] Determine each adjusted decoded character corresponding to each decoded character based on the adjusted bar width and unadjusted empty width or adjusted empty width and unadjusted bar width in each decoded character, and for each ...

Embodiment 4

[0088] On the basis of the above-mentioned embodiments, in the embodiment of the present invention, determining the type of the barcode to be decoded includes:

[0089] Identify the bar space width of the start character and / or end character of the barcode to be decoded;

[0090] The type of the barcode to be decoded is determined according to the pre-stored standard bar-space width corresponding to the start character and / or end character of each type of barcode, and the recognized bar-space width.

[0091] In the embodiment of the present invention, when determining the type of the barcode to be decoded, it may be determined according to the initial character of the barcode to be decoded, and the electronic device stores the standard of the initial character corresponding to each type of barcode Bar space width, when the electronic device recognizes the bar space width of the initial character of the barcode to be decoded, it can compare the identified bar space width with t...

Abstract

The invention discloses a barcode decoding method and apparatus used for solving the problem of inaccurate decoding possibly caused by width change of bar gaps during ink spilling or overexposure of barcodes in the prior art. The method includes: determining a first ratio of the bar gap width of each identification character in a to-be-decoded barcode, wherein the identification character comprises a starting character and / or a termination character; identifying a second ratio of the bar gap width of a standard template of each identification character of the type of the to-be-decoded barcode; and adjusting the bar width or the gap width in each decoding character according to a scaling proportion determined by the first ratio and the second ratio, and decoding each adjusted decoding character. According to the method and apparatus, the bar gap width is adjusted according to the scaling proportion, the adjusted bar gap width is close to the standard bar gap width, the change of the bar gap width due to the condition of ink spilling or overexposure of the barcodes is reduced, the adjusted decoding characters are decoded, and the decoding accuracy can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of barcodes, in particular to a barcode decoding method and device. Background technique [0002] Bar code technology is an emerging technology developed on the basis of computer technology and information technology that integrates coding, printing, identification, data collection and processing. Barcode technology is widely used in business, library management, warehousing, post and telecommunications, transportation and industrial control due to its advantages of fast, accurate, reliable and low cost, and is bound to play an important role in the emerging "Internet of Things" applications. role. [0003] In the barcode detection scheme based on the vision system, it is mainly divided into barcode positioning and barcode decoding. In the barcode decoding process, how to improve the decoding accuracy has always been an important research topic. [0004] The existing barcode decoding scheme mainly include...
