Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] The present invention adopts the method of scanning, recognizing and assembling at the same time, and the decoding is completed after the scanning is completed, effectively dealing with the problem that all the empty images of the barcode image cannot be completely scanned by any scanning line in the actual situation, and cannot be decoded successfully. At the same time, it can solve the problem of how to combine non-stained areas, improve the decoding rate, and has a strong decoding ability for images with interference.

[0031] The invention provides embodiments: as figure 1 As shown, first determine the barcode type, and determine the scanning and decoding parameters according to the barcode type, including the following steps:

[0032] (1) Determine the type of the barcode first. For the dirty scanning line, it is very likely that the barc...

Abstract

The invention relates to a high-performance barcode decoding method. The method comprises the steps that the barcode type is judged firstly, scanning and decoding parameters are determined according to the barcode type, and scanning, identification and combination are performed simultaneously and then scanning is completed so that decoding is completed. Compared with the methods in the prior art, the problems in the actual situation that any one scanning line cannot completely scan all the empty image of a barcode image and cannot successfully decode can be effectively handled by the method so that the decoding rate can be enhanced. Meanwhile, the high-performance barcode decoding method also has high performance and has high decoding capacity for the image having interference.

Description

technical field [0001] The invention belongs to the technical field of barcode identification, and in particular relates to a barcode decoding method. Background technique [0002] Barcode recognition technology is an emerging technology developed on the basis of information technology and computer technology. It is widely used in various fields due to its fast, accurate, reliable and low-cost recognition; barcodes are composed of multiple "bars" arranged in parallel. " and "empty" units, the information of the barcode is expressed through the combination of different widths of the bar and space; the barcode recognition system can be divided into line scanning and surface scanning. Line scanning acquires an image of one scanning line at a time, and surface scanning acquires several scanning lines at a time; in practical applications, due to various conditions such as wear, printing defects, and light interference, the actually obtained barcode image will have various interf...
