Decoding chip of RSS (Really Simple Syndication) bar code

Abstract

The invention provides a decoding chip of an RSS (Really Simple Syndication) bar code, comprising a scanning module, a boundary identification module, a direction identification module, a bar space boundary processing module, a search feature identification module, a sign character acquisition module, a decoding fragment storage, an RSS bar code combination logic judgment module and a decoding module, wherein the scanning module generates scanning coordinates; the boundary identification module acquires the bar space boundary point of a bar code image; the direction identification module acquires the direction of the bar code; the bar space boundary processing module acquires the bar space boundary according to the direction of the bar code; the search feature identification module acquires sign parameters according to the bar space boundary; the sign character acquisition module works out the sign character of an RSS bar code combination; the decoding fragment storage stores the sign character of the RSS bar code combination; the RSS bar code combination logic judgment module acquires the sign character of an integral RSS bar code fragment combination meeting decoding standards; and the decoding module carries out error check and decoding so as to acquire bar code information. The decoding chip of the RSS bar code acquires the sign character of the integral RSS bar code fragment combination through splicing various bar code fragment combinations, thereby improving the recognition rate and the decoding success rate of the RSS bar code.

Description

【Technical field】 [0001] The invention relates to a barcode decoding device, in particular to an RSS barcode decoding chip. 【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 expressed by the different widths and positions of the bars a...
