Cov khoom lag luam OCR/OCV yuav hloov cov tshuab luam ntawv qub

Dab tsi yog Optical Character Recognition (OCR)?

Optical character recognition (OCR) thev naus laus zis yog cov txheej txheem ua lag luam zoo uas txuag lub sijhawm, nqi thiab lwm yam kev pabcuam los ntawm kev siv cov ntaub ntawv rho tawm thiab khaws cia.

Optical character recognition (OCR) qee zaum hu ua kev lees paub ntawv.Ib qho kev pabcuam OCR rho tawm thiab rov tsim cov ntaub ntawv los ntawm cov ntaub ntawv scanned, cov duab hauv lub koob yees duab thiab cov duab nkaus xwb pdfs.OCR software muab cov ntawv sau rau ntawm daim duab, muab tso rau hauv cov lus thiab tom qab ntawd muab cov lus tso rau hauv kab lus, yog li ua kom nkag mus rau thiab kho cov ntsiab lus qub.Nws kuj tshem tawm qhov xav tau ntawm phau ntawv sau cov ntaub ntawv nkag.

OCR systems siv kev sib xyaw ntawm cov khoom siv kho vajtse thiab software los hloov cov ntaub ntawv lub cev, luam tawm mus rau hauv cov ntawv nyeem tau lub tshuab.Kho vajtse - xws li lub tshuab ntsuas qhov muag lossis lub rooj tsav xwm tshwj xeeb - luam lossis nyeem ntawv;Tom qab ntawd, software feem ntau ua haujlwm rau kev ua haujlwm siab heev.

OCR software tuaj yeem ua kom zoo dua ntawm kev txawj ntse txawj ntse (AI) los siv ntau txoj hauv kev ntawm kev paub tus cwj pwm ntse (ICR), xws li txheeb xyuas cov lus lossis cov qauv ntawm kev sau ntawv.Cov txheej txheem ntawm OCR feem ntau yog siv los hloov cov ntaub ntawv raug cai lossis keeb kwm yav dhau los rau hauv pdf cov ntaub ntawv kom cov neeg siv tuaj yeem hloov kho, tsim thiab tshawb xyuas cov ntaub ntawv zoo li tsim nrog cov lus sau.

Optical character recognition ua haujlwm li cas?

Optical character recognition (OCR) siv lub scanner los ua cov ntaub ntawv lub cev ntawm daim ntawv.Thaum tag nrho cov nplooj ntawv tau theej, OCR software hloov cov ntaub ntawv mus rau hauv ob-xim lossis dub-thiab-dawb version.Cov duab scanned lossis bitmap raug tshuaj xyuas rau thaj chaw teeb thiab tsaus, thiab thaj chaw tsaus raug txheeb xyuas raws li cov cim uas yuav tsum tau lees paub, thaum lub teeb pom kev yog keeb kwm yav dhau.Tom qab ntawd cov chaw tsaus yog ua tiav kom pom cov tsiaj ntawv lossis cov lej.Cov theem no feem ntau yog tsom rau ib tus cwj pwm, lo lus lossis thaiv cov ntawv ntawm ib lub sijhawm.Cov cim yog tom qab ntawd txheeb xyuas siv ib qho ntawm ob lub algorithms - kev lees paub qauv lossis kev lees paub tshwj xeeb.

Kev lees paub tus qauv yog siv thaum OCR qhov kev pab cuam pub cov piv txwv ntawm cov ntawv nyeem hauv ntau hom fonts thiab hom los sib piv thiab paub cov cim hauv cov ntaub ntawv scanned lossis cov duab.

Kev kuaj pom muaj txiaj ntsig tshwm sim thaum OCR siv cov cai hais txog cov yam ntxwv ntawm tsab ntawv tshwj xeeb lossis tus lej kom paub txog cov cim hauv daim ntawv scanned.Cov yam ntxwv muaj xws li tus naj npawb ntawm cov kab, hla kab lossis nkhaus hauv ib tus cim.Piv txwv li, tsab ntawv loj "A" khaws cia ua ob kab kab pheeb ces kaum uas tau ntsib nrog kab kab rov tav hla nruab nrab.Thaum tus cwj pwm raug txheeb xyuas, nws tau hloov mus rau hauv ASCII code (American Standard Code for Information Interchange) uas lub khoos phis tawj siv los tswj cov kev tswj xyuas ntxiv.

Ib qhov kev pab cuam OCR kuj txheeb xyuas cov qauv ntawm daim duab duab.Nws faib cov nplooj ntawv rau hauv cov ntsiab lus xws li thaiv cov ntawv, rooj lossis cov duab.Cov kab tau muab faib ua cov lus thiab tom qab ntawd ua cov cim.Thaum cov cim tau raug cais tawm, qhov kev pab cuam muab piv rau lawv nrog cov txheej txheem cov duab.Tom qab ua tiav txhua qhov kev sib tw, qhov kev zov me nyuam nthuav qhia koj nrog cov ntawv lees paub.

OCR feem ntau yog siv los ua cov cuab yeej zais, ua kom muaj ntau yam kev paub zoo thiab cov kev pabcuam hauv peb lub neej txhua hnub.Tseem ceeb - tab sis tsis tshua paub - siv cov ntaub ntawv rau OCR thev naus laus zis suav nrog cov ntaub ntawv nkag-automation, pab cov neeg dig muag thiab qhov muag tsis pom kev thiab kev txheeb xyuas cov ntaub ntawv rau kev tshawb fawb xyaw, xws li phau ntawv hla tebchaws, daim ntawv tso cai, daim ntawv xa nyiaj, daim ntawv teev nyiaj hauv tuam txhab, daim npav lag luam thiab daim ntawv lees paub tsis siv neeg. .

 

Nta piv rau ib txwm scanners:

1. Lub teeb yuag, yooj yim nqa thiab nruab;

2. Lub sijhawm luam theej duab luv luv, lub sijhawm luam theej ib txwm yog 1-2S, thiab koj tuaj yeem tau txais tam sim ntawd;

3. Tus nqi qis

4. Nws tuaj yeem ua OCR lees paub ntawm cov duab ntes, hloov cov duab rau hauv WORD cov ntaub ntawv kho tau, thiab tau sau lawv;

5. Incorporating paperless fax technology, txawm tias tsis muaj lub tshuab fax, koj tseem tuaj yeem xa faxes, uas ua kom zoo dua fax efficiency;

 

Optical character recognition siv rooj plaub

Cov ntaub ntawv siv paub zoo tshaj plaws rau kev paub txog tus cwj pwm kho qhov muag (OCR) yog hloov cov ntaub ntawv luam tawm mus rau hauv cov ntaub ntawv nyeem tau tshuab.Thaum ib daim ntawv luam theej duab dhau los ntawm kev ua OCR, cov ntawv ntawm cov ntaub ntawv tuaj yeem hloov kho nrog cov lus processor zoo li Microsoft Word lossis Google Docs.

OCR tso cai rau kev ua kom zoo dua ntawm cov qauv ntaub ntawv loj los ntawm kev hloov cov ntawv thiab cov duab scanned rau hauv tshuab nyeem tau, tshawb nrhiav pdf cov ntaub ntawv.Kev ua haujlwm thiab khaws cov ntaub ntawv tseem ceeb yuav tsis tuaj yeem ua haujlwm yam tsis muaj kev thov OCR thawj zaug hauv cov ntaub ntawv uas cov ntawv txheej tsis tau tshwm sim.

Nrog OCR cov ntawv lees paub, cov ntaub ntawv luam theej tuaj yeem muab tso rau hauv cov ntaub ntawv loj uas tam sim no tuaj yeem nyeem cov neeg siv cov ntaub ntawv los ntawm cov ntaub ntawv hauv txhab nyiaj, cov ntawv cog lus thiab lwm cov ntaub ntawv luam tawm tseem ceeb.Tsis txhob muaj cov neeg ua haujlwm tshuaj xyuas cov ntaub ntawv suav tsis txheeb thiab muab cov ntaub ntawv nkag mus rau hauv qhov kev ua haujlwm loj-cov ntaub ntawv ua haujlwm, cov koom haum tuaj yeem siv OCR los ua haujlwm nyob rau theem nkag ntawm cov ntaub ntawv mining.OCR software tuaj yeem txheeb xyuas cov ntawv hauv daim duab, rho tawm cov ntawv hauv cov duab, txuag cov ntawv nyeem thiab txhawb nqa jpg, jpeg, png, bmp, tiff, pdf thiab lwm hom.

Ntawm qhov pib ntawm qhov no, Hampo muajlaunched series ntawm koob yees duab modules los ntawmqho los ntawm5MP-16MP lub koob yees duab ntawm txhais.Thaum pib ntawm Hampo txoj kev loj hlob theem, peb pab neeg tau tsim thawj hom 5MP usb lub koob yees duab module rau cov ntaub ntawv ceev ceev scanner;Nrog rauxav tau ntawmkev ua lag luam, 8MP, 13MP, thiab txawm tias 16MP USB lub koob yees duab modules tauua.Dab tsi's ntau, qhov kev thov rau ib lub koob yees duab, mus rau 2 lub koob yees duab, thiab ntau lub koob yees duab tau siv rau cov ntaub ntawv scanner.
