Abstract

The invention provides a module for calculating bar space boundary pixel points. The module comprises a scanning boundary acquiring unit and a linear scanning unit, wherein the scanning boundary acquiring unit is used for acquiring bar space boundary points and a bar code direction and calculating a scanning boundary; and the linear scanning unit is used for selecting a scanning start point and a scanning final point corresponding to the scanning start point according to the scanning boundary and calculating coordinates of pixel points on a straight line between the scanning start point and the scanning final point. The method also provides a method for calculating the bar space boundary pixel points. The module for calculating the bar space boundary pixel points can adjust a decoding direction according to the bar code direction, acquire an accurate coordinate value of a bar code boundary and enhance a decoding success ratio.

Description

【Technical field】 [0001] The invention relates to the technical field of barcode identification, in particular to a bar-space boundary pixel point calculation module and a calculation method applied in a barcode identification 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] 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 ar...
