One-dimensional barcode decoding chip

Abstract

The invention provides a one-dimensional barcode decoding chip which comprises a scanning module, a border identification module, a direction identification module, a bar empty border processing module, a symbol parameter identification module, a symbol and character acquisition module and a decoding module; the scanning module produces scanning coordinates; the border identification module reaches barcode images according to the scanning coordinates and calculates the read image pixels so as to acquire the bar empty border points of the barcode images; the direction identification module calculates and obtains barcode directions according to the bar empty border points acquired by the border identification module; the bar empty border processing module processes the barcode images according to the barcode directions, so as to acquire the bar empty borders in the barcode images; the symbol parameter identification module calculates and acquires symbols and characters according to the bar empty and symbol parameters; and the decoding module converts the symbols and the characters into barcode information. The one-dimensional barcode decoding chip adopts a hardware assembly line structure, is applicable to the assembly line operation and parallel processing of the barcode images, and has high processing speed.

Description

【Technical field】 [0001] The invention relates to the technical field of barcode identification, in particular to a one-dimensional barcode decoding chip. 【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] 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 wi...
