Digitising phau ntawv. Yuav ua li cas yuav ua rau nws?

Nyob rau hauv lub ntiaj teb no muaj ib tug tag nrho tiam ntawm qhov tseeb khoom, uas yuav pab kom mus cuag ib tug siab lub hom phiaj - mus tau yooj yim qhia paub thiab khaws cia rau lub achievements ntawm yav dhau los tau ntau tiam, nyob rau hauv daim ntawv ntawm e-phau ntawv. Nyob rau hauv no tsab xov xwm, peb yuav kawm txog cov theem pib hom ntawm cov khoom rau digitizing phau ntawv.

Flatbed scanner - nws yog ib tug ntawm cov uas pheej yig tshaj hom ntawm phau ntawv scanner, uas yog siv rau cov zoo li las khoom. Los ntawm tsev neeg scanners, uas muaj ntau yam ntawm peb muaj nyob rau hauv tsev, lawv txawv nyob rau hauv hais tias lawv muaj ib tug ho muaj dua PP ceev thiab kev daws teeb meem. Nyob rau hauv tas li ntawd, ib co qauv ntawm cov ntsiav tshuaj, xws li Avision scanner yog tseem txawm peem rau nrog ib tug tshwj xeeb "txiav", uas tiv thaiv cov tsos ntawm "blackout" uas tshwm nyob rau hauv lub scanned ntawv luam ntawm cov phau ntawv. Qhov siab tshaj plaws phau ntawv hom ntawv - A3.

Planetary scanners yog cov neeg uas scan caij yog nyob rau saum. Xws li Digitisation ntawm tsawg thiab tseem ceeb khoom no tshwm sim nyob rau hauv ib tug contactless yam. Qhov no cov khoom yog txawm peem rau nrog ib tug bracket uas tso cai rau koj mus dlhos cov yam thickness ntawm cov phau ntawv, thiaj li tsis mus ua puas lub hauv paus thiab gluing. Planetary scanners pom tau hais tias qhov zoo tshaj plaws ib tug rau cov tsev qiv ntawv nrog muaj zog collections ntawm thaum ntxov sau phau ntawv. Mus ua hauj lwm nrog xws li cov khoom xwb 1 tus neeg yuav tsum tau. Lub PP txheej txheem yog tej yam yooj yim thiab zoo ib yam li cov phau ntawv nyeem ntawv - lub neeg teb xov tooj puv cov nplooj ntawv ntawm ib phau ntawv, thiab lub Upper PP caij "cov ntawv luam" reversal. Tag nrho cov ntxiv ua hauj lwm (txiav tig, kawm tuab si lug cov nplooj ntawv horizontally, xim kho) yuav tsum tau siv cov ua-nyob rau hauv scanner software los yog lwm yam mob tshwj xeeb ncaj qha mus rau lub computer.

Qhia ob peb yooj yim sib txawv ntawm planetary scanners:

• Teeb pom kev zoo (kev coj-teeb pom kev zoo los yog flash. Scanning nrog txias teeb pom kev zoo technology tiv thaiv cov cua kub qhov twg los, uas adversely muaj feem xyuam rau cov qauv ntawm cov ntawv. Tsis zoo li infrared los yog ultraviolet lub teeb).
• Hom PP caij (cov koob yees duab los yog PP lub taub hau).
• Staple (kab rov tav los yog V-zoo li tus).
• Ib tug qauv rau kev xa nplooj ntawv (manually, txiav).
• Lub xub ntiag ntawm lub pressing iav (rau leveling qhov chaw ntawm cov nplooj ntawv).

Digitisation ntawm lub "classical" planetary scanners kom muaj tagnrho sawv cev kav Book2net German chaw tsim tshuaj paus Microbox thiab cov khoom ntawm Belgian tshwj xeeb Zeutchel.

Planetary ntau scanners. Thaum koj xub mus ntsib tus qauv Zeta thoob ntiaj teb chaw tsim tshuaj paus Zeutchel scanners, thawj thought uas tshwm sim yog hais tias lub developers tau tshwm sim los ntawm cov kua khoom. Qhov no scanner yuav kuj yuav muaj ib yam tshiab rau tej tsev qiv ntawv thiab ib qho ntxiv attraction. Tej qauv nyob rau hauv lub ntiaj teb no yog siv nyob rau hauv kev nyeem ntawv chav ntawm archives, puas, cov tsev qiv ntawv. Nyob rau hauv tas li ntawd mus tsim kev kawm, lawv yog ib qho yooj yim mus siv - txhua rau lawv tus kheej tsis muaj teeb meem yuav luam theej duab thiab txuag cov duab mus rau ib tug flash drive. Ib tug multi-kov vaj huam sib luag tso cai rau koj kom sai li sai saib qhov tshwm sim.

Feem ntau cov no yog cov "kev cai" qauv muaj built-nyob rau hauv software uas txiav dab cov dluab - nyob rau hauv particular, tshem tawm cov ntiv tes (uas tus neeg siv tuav cov tsab vim hais tias cov scanner tsis de cov iav), dlhos cov duab thiab tej qhov nqaij ntuag U-lem nyob rau hauv ob cais cov nplooj ntawv.

Photo scanners. Tag nrho cov qauv uas yog raws li nyob rau hauv cov koob yees duab nruab nrog ib tug V-zoo li tus bracket. Yog li ob tug koob yees duab nyob rau tib lub sij hawm ua ib tug yees duab ntawm sab laug thiab txoj cai cov nplooj ntawv. Txawm li cas los, nyob rau hauv thiaj li yuav tau txais cov kev cai teeb pom kev zoo duab - yuav tsum tau zoo saib xyuas rau lub teeb, kom tsis txhob muaj lub "glare", uas yog ua tau nruab nrog ib tug tag nrho cov yees duab studio. Los ntawm txoj kev, Atiz khoom los nrog ib tug tshwj xeeb cover los tiv thaiv los ntawm lub teeb.

Tsis tas li ntawd, V-zoo li tus bracket yog feem ntau siv rau cov PP ntawm cov phau ntawv uas ua tsis tiav qhib lub. Feem ntau cov feem ntau, nws tshwm sim nrog cov ntaub ntawv, uas tau txom nyem restoration (thaum sewn phau ntawv / glued thiab thaum qhib 180 degrees yuav puas tsab).

Nws yog ntseeg hais tias qhov no Photo Scanner - kev lag kev luam muaj txiaj ntsim. Txawm li cas los, tus nqi ntawm lub scanner nyob feem ntau nyob rau hauv tus qauv ntawm lub koob yees duab, yog li - lawv tus nqi yuav ywj faj ywj fwm.

Nyob rau hauv ib tug network koj yuav saib tau ib tug ntau ntawm manuals rau tsim photoscanners nyob rau hauv tsev. Kwv yees li ntawm tus nqi ntawm kev tsim kho ntawm no complex yuav mus txog $ 300 (tsis suav tus nqi ntawm lub koob yees duab).

Neeg Hlau-scanners. 'Nrov', los yog es twb universally admired, tiam sis feem ntau tsis tau yus nyob rau hauv industrial PP yog robotic crawlers. Technically, lawv nco ntsoov Photo Scanner, tab sis flipping nplooj ntawv txheej txheem rau lub hauv paus ntsiab lus ntawm lub tshuab nqus tsev (nyob rau hauv lwm yam lus, nws yog, nyob rau hauv qhov tseeb, zoo li ib lub tshuab nqus tsev ntxhua khaub ncaws, uas yog ntawm cov huab cua khiav picks cov nplooj ntawv). Yog lwm proprietary technology page raws - bionic ntiv tes, uas tsa lub ntsis ntawm tus tib neeg index ntiv tes thiab muaj peev xwm tig cov nplooj ntawv ntawm ib phau ntawv.
Nws yog txaus ntshai rau siv xws li scanners rau nqi phau ntawv - vim hais tias ntawm lub thickness ntawm daim ntawv, vim hais tias cov ntawv tej zaum yuav puas nplooj ntawv tej zaum yuav tawg. Nws tseem yuav tshwm sim hais tias cov nplooj ntawv glued ua ke, li ntawd, peb yuav tsum tau ceev faj rau uas ploj lawm cov nplooj ntawv. Manufacturers xws li ua qauv tau sau tseg tias tsuas yog ib tug neeg yuav tsum tau rau simultaneous lag luam los ntawm ob peb ntawm cov scanners, uas yuav saib xyuas cov txheej txheem.

Txawm li cas los, raws li cov dab neeg scan tswv, uas tau muaj lub sij hawm mus ua hauj lwm nrog xws li cov khoom, ib tug ntau ntawm lub sij hawm lub sij hawm nyob rau hauv uas ploj lawm cov nplooj ntawv thiab "kev ncaj ncees" ntawm puas phau ntawv.

Ntawm science ntawv tseeb los yog lub neej yav tom ntej, uas yog nce

Tsis ntev dhau los, cov xov xwm qhia nyob rau hauv cov tsos ntawm cov phau ntawv PP system uas tso cai rau koj mus luam theej duab txog li 250 nplooj ntawv ib feeb.

Japanese developers muaj kev tswj kom tau ib tug tshaj plaws ceev los ntawm kev siv ib tug ca duab reconstruction algorithms ntawm tus yees duab page raws. Yeej muaj tseeb, cov nqe lus nug seem siv ntawm xws li ib tug system rau tuab cov phau ntawv thiab muaj ib tug complex ntoo khaub lig-linking.

Cov neeg kom tiam ntawm kev txawj ntse los qhia rau lawv nrog lawv cov me nyuam thiab nqa los ntawm lub centuries. Cov ntaub ntawv rau tag nrho cov tswv yim thiab tsis yog cov phau ntawv uas koj pom hauv no qhov chaw.
