Study Of The Method Of One-Dimensional Bar Code Image Identification

Firstly the paper introduces technology characteristic of EAN-13 and the basic components of the bar code image identification system. Then some problems are analyzed in the print of paper ark bar code. The paper contraposes some problems such as the wide line, the thinned line, the uneven color, the parting line, redundant printing ink and various cases of noises when the bar code image is input. We put forward the algorithms of the bar code image processing and the method of correcting and bar code identification based on the bar code image identification. On the base of it, the software of the bar code identification is developed. At the same time the paper shows some examples of the software test and the practicability of the method is demonstrated.The feature of the paper is that the bar code bitmap and the characteristic pixels are statistically analyzed. Therefore the means of obtaining the bar code information is more advanced and reliable, it makes for advancing the efficiency of the first identification. Comparing with the bar code light and electricity identification technology of one dimension bar code, this kind of method is obviously advantaged.
