Because the dsp system has the very powerful function of computing and can fulfill the image processing in very short time , an experimental real - time processing system for bar code images is developed by using a dsp based chip - tms320ve5410 in the thesis . the revolved hardware circuits , revolved softwares and design notices of the system are given 由于dsp系統(tǒng)的運(yùn)算功能強(qiáng)大,可以在較短的時(shí)間內(nèi)完成圖像處理運(yùn)算,本文采用基于dsptms320vc5410芯片開(kāi)發(fā)了條碼圖像實(shí)時(shí)處理實(shí)驗(yàn)系統(tǒng),給出了dsp系統(tǒng)的相關(guān)的硬件電路圖、相關(guān)的軟件及設(shè)計(jì)此系統(tǒng)需要注意的事項(xiàng)。
The bar code image recognition program coded by vc + + 6 . 0 is compared with the experimently real - time processing system , and the results show mat the processing speed of the latter is very greater than the speed of the front studies in the thesis promote the automatic identification of bar code image and its practicalization and present some ideas of how to improve the bar code image processing system based on dsp 本文對(duì)vc + + 6 . 0編寫(xiě)的條碼圖像識(shí)別程序和條碼圖像實(shí)時(shí)處理實(shí)驗(yàn)系統(tǒng)比較,后者的處理速度遠(yuǎn)高于前者。本論文的研究,為條碼圖像的自動(dòng)識(shí)別和實(shí)用化做了一些促進(jìn)工作,對(duì)基于dsp的條形碼圖像處理系統(tǒng)改進(jìn)發(fā)展提出了自己的看法。
The paper contraposes some problems such as the widening line , the narrowing line , the unequal color , the parting line , redundant printing ink and various cases of noises in the bar code image input etc , on which the algorithms of the bar code digital image processing and the algorithms of the bar code image identification are put forward . accordingly the method of correcting errors which bases on the bar code image identification is established 分析了瓦楞紙箱條碼印刷中存在的問(wèn)題,針對(duì)條碼線條展寬、細(xì)化、著色不均、斷條、冗余墨漬以及條碼采集中可能出現(xiàn)的噪聲等問(wèn)題,文中提出相應(yīng)的數(shù)字圖像處理算法和條碼圖像識(shí)讀方法,并進(jìn)一步提出一種基于圖像辨識(shí)技術(shù)的條碼識(shí)讀糾錯(cuò)方案。
