- I-OCR ikuvumela ukuthi uguqule izithombe zamadokhumenti zibe umbhalo okhethekayo noseshekayo.
- Kukhona amathuluzi asheshayo aku-inthanethi kanye nesofthiwe ethuthukisiwe njenge-OCRmyPDF yokwenza izinto ngokuzenzakalela.
- Ifomethi ye-PDF/A ibalulekile ukuqinisekisa ukusebenza okusemthethweni kanye nokugcinwa kwengobo yomlando kwesikhathi eside.
- I-OCRmyPDF ihlanganisa i-Tesseract kanye ne-GhostScript ukuze ithuthukise ukwenziwa kwefayela libe yidijithali ngobuningi.
Ngiyaqiniseka ukuthi sekuke kwenzeka kuwe ngaphambili: unenqwaba yamaphepha askeniwe noma izithombe zamadokhumenti eziyizithombe nje, futhi uma uzama ukusesha igama elingukhiye noma ukukopisha isigaba, ikhompyutha ayiboni noma yimuphi umbhalo . Kuyacasula kakhulu, ikakhulukazi uma ubhekene namafayela okufundwayo kuphela noma amaskeni amadala abukeka njengezindonga zamaphikseli ezingadluleki.
Ukuze sixazulule le nkinga, sidinga ukusebenzisa ubuchwepheshe obubizwa ngokuthi i-OCR (Optical Character Recognition) . Ngokuyisisekelo, uhlelo oluhlaziya izithombe zedijithali, luhlonze ukuthi yiziphi izimpawu ezihambisana nohlamvu ngalunye lwezinhlamvu, bese luziguqula zibe idatha yombhalo ekhonjisiwe . Ngenxa yalokhu, singaguqula i-PDF "efile" ibe idokhumenti ebukhoma lapho ungakhetha khona, ukopishe, futhi useshe noma yiliphi igama ngokuphazima kweso.
Amathuluzi aku-inthanethi kanye nezinye izindlela ezisheshayo
Uma ungafuni ukuhlushwa ukufaka isofthiwe eyinkimbinkimbi, kunezinketho ezilula kakhulu. Amathuluzi afana ne -iLovePDF ahlanganisa izinjini ze-OCR ezikuvumela ukuthi uguqule amafayela askeniwe abe amadokhumenti lapho umbhalo ungakhethwa khona. Anikeza nethuba lokuguqula i-PDF ibe yifomethi ye-Word ehlelekayo , yize ukuze kube nokunemba okukhulu kule nqubo, kuvame ukudingeka inguqulo ye-Premium.
Kulabo abathanda ukusebenza endaweni yakini ku-Windows, i-PDF24 Creator iyindlela engcono kakhulu enezici ezifanayo zokuqaphela umbhalo. Lawa mathuluzi afaneleka kakhulu uma unenani elincane lamadokhumenti futhi udinga ikhambi elisheshayo ngaphandle kokungena kuzilungiselelo zobuchwepheshe.
Inselele yefomethi ye-PDF/A kanye nokuphathwa komphakathi
Ezindaweni zobungcweti noma zomthetho, njengasepulatifomu yeLexNET eSpain, akwanele ukuthi i-PDF "ibe yinto engaseshekayo" nje. Yilapho-ke indinganiso ye-PDF/A iqala khona ukusebenza , okuyinguqulo eyenziwe kahle ye-PDF eyenzelwe ukugcinwa kwesikhathi eside, isusa izinto ezingadingekile ezingenza ifayela lingafundeki esikhathini esizayo.
Kuvamile kakhulu ukuthi ochwepheshe abaningi bathumele amadokhumenti edijithali bekholelwa ukuthi ayahlangabezana nezidingo, bese kamuva bathola ukuthi izimangalo zabo zenqatshwa ngenxa yamaphutha enqubo. Ukuze idokhumenti isebenze kulezi zimo, kumele kube ifayela le-PDF/A elikhiqizwe ngesofthiwe evumela ukudalwa kombhalo ohlelekayo ongaseshwa ngempela.
Ukwazi i-OCRmyPDF: Isixazululo Esiphelele Sobuchwepheshe
Uma udinga ukucubungula idatha enkulu noma ukwenza ngokuzenzakalelayo ukuhamba komsebenzi wakho, i-OCRmyPDF iyithuluzi eliphelele. Leli phakethe lisindisa impilo yangempela ngoba lihlanganisa amandla e -Tesseract OCR, i-GhostScript, i-Python 3, kanye ne-Img2PDF ukuze wengeze ungqimba lombhalo olungabonakali phezu kwesithombe sokuqala se-PDF.
Ukufakwa nokucushwa ezindaweni ze-Linux
Ukuze uqale ukusebenza, kungcono usebenzise ukusatshalaliswa okufana I-Debian noma i-UbuntuInqubo iqala ngokufaka iphakheji eyinhloko usebenzisa umyalo apt-get install ocrmypdfIphuzu elibalulekile ukuthi iTesseract idinga amaphakheji okuqeqesha athile kolimi ngalunye; isibonelo, ukuze uhlelo lukwazi ukubona kahle iSpanishi, isiGalician noma isiCatalan, amaphakheji kumele afakwe tesseract-ocr-spa, tesseract-ocr-glg y tesseract-ocr-cat ngokulandelana.
Ukuzenzakalela kusetshenziswa ama-Hotfolder nama-Scripts
Enye yezindlela eziphumelela kakhulu zokusebenzisa i-OCRmyPDF ukudala i- uhlelo lwefolda eyabiwe (Ama-Hotfolders). Ukuhamba komsebenzi kusebenza kanje: iskena sibeka i-PDF kufolda yenethiwekhi (efakwe nge- mount.cifs (Uma sisebenzisa iWindows), iskripthi sithola ifayela bese sisebenzisa umyalo we-OCR wokufaka umphumela wokugcina kufolda yokuphuma.
Ukuze lokhu kwenziwe ngokuzenzakalela futhi kugwenywe ukunamatheliswa esikrinini, umsebenzi we-cron uhlelwe ukuthi usebenzise umyalo njalo ngeminithi, ngaleyo ndlela uguqule noma yikuphi ukuskena kube yi-PDF/A engasesheka.
Ukuhlaziywa kwemiyalo eyisihluthulelo nezinketho
Umyalo oyisisekelo we-OCRmyPDF unikeza izinketho eziningana zokupholisha umphumela wokugcina:
- –ulimi: Chaza ulimi lombhalo (isb.
spa(ngesiSpanishi) ukuze injini ingadideki izinhlamvu. - –amakhasi ajikelezayo: Ithola ukuthi kukhona ikhasi eliskeniwe libheke phansi futhi Ijikeleza ngokuzenzakalelayo..
- –ideski: Qondisa idokhumenti uma i-feeder ezenzakalelayo iyishiye igobile kancane, yize lokhu kungase ukukhuluphala kusuka kufayela.
- –kuhlanzekile futhi –kuhlanzekile-kokugcina: Lezi zinketho zihlanza umsindo wesithombe ngaphambi nangemva kokucutshungulwa ukuze kuthuthukiswe ukunemba, yize ziphinde zithinte usayizi wokugcina we-PDF.
Ukuze kube nebhalansi efanele phakathi kwekhwalithi nosayizi, kunconywa ukusebenzisa inhlanganisela elula yokuhlanza nolimi, ugweme ukucubungula ngokweqile okufutha amafayela ngokungadingekile.
Ikhono lokuguqula izithombe ezimile zibe amadokhumenti anezinkomba liguqula ngokuphelele ukuphathwa kolwazi, lenze amafayela amadala noma asebenza ngezikhulu atholakale ngokusesha okusheshayo. Kungakhathaliseki ukuthi kusetshenziswa izinsizakalo zamafu emisebenzini eyenzeka kanye noma kusetshenziswa ingqalasizinda nge-OCRmyPDF ukuze kwenziwe ngokuzenzakalelayo imisebenzi yokusebenza kumaseva e-Linux, isihluthulelo sisekukhetheni ithuluzi elifanelana kahle nenani lamadokhumenti kanye nezidingo zomthetho zefomethi yokugcina.
