Problems solved by technology

One-dimensional barcodes only express information in one direction (generally the horizontal direction), but do not express any information in the vertical direction, so the information capacity and space utilization rate are low, and the barcode cannot be recognized after it is damaged
[0004]The two-dimensional barcode is composed of black and white specific geometric figures distributed in the two-dimensional direction according to certain rules, which can express information in the two-dimensional direction, so the information The capacity and space utilization are low, and it has a certain verification function
This cyclic decoding process often takes a lot of time, thus greatly reducing the decoding speed

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Such as figure 1 as shown, figure 1 is a schematic diagram of the barcode image parallel processing architecture of the first embodiment of the present invention. In the first embodiment of the present invention, at least two processing units 101 and 102 are set in the barcode decoding device 100 . The processing units 101 and 102 are recognition units corresponding to different code systems, that is, the processing units 101 and 102 can respectively use recognition rules of different code systems to perform barcode recognition. For example, the processing unit 101 is a one-dimensional barcode recognition unit, and the processing unit 102 is a PDF417 barcode recognition unit. In addition, the barcode decoding device 100 can further be provided with a plurality of processing units to respectively correspond to the barcode recognition process ...

Abstract

The invention discloses a barcode decoder for supporting multi-code system parallel processing. The barcode decoder comprises at least two processing units. The at least two processing units recognize the same input barcode image by utilizing recognition rules aiming at different code systems respectively. Through the method, the multiple processing units are utilized to recognize the same barcode image according to different recognition rules, so the recognition speed of the barcode image is improved.

Description

【Technical field】 [0001] The invention relates to a barcode decoding device, in particular to a barcode decoding device supporting parallel processing of multiple code systems. 【Background technique】 [0002] Barcode technology is an emerging technology that integrates coding, printing, identification, data collection and processing developed on the basis of computer technology and information technology. 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] Currently widely used barcodes include one-dimensional barcodes and two-dimensional barcodes. A one-dimensional barcode, also known as a linear barcode, is composed of multiple "bar" and "space" units arranged in parallel, and the barcode information is expresse...
