Nyob rau hauv xyoo tas los, raws li qhov khoom yog ntim thiab puv, nws tau ua ntau tus nplua nuj thiab zoo nkauj. Ib yam tshiab khoom muag ntsiag to tshwm hauv neeg lub neej txhua hnub. Koj puas pom qhov ntxim me ntsis daim npav tso rau hauv cov khoom noj khoom haus? 7 Tilting the card los yog tsiv lub npav rov qab yuav pom txhua yam zoo.
Qhov no yog qhov khoom ua los ntawm kev siv lub tshuab luam yeeb tso tawm. Nws yog dav siv hauv ntim thiab hnav khaub ncaws cov khoom, kev lag luam luam, kev thaij thiab kev kawm txuj ci, ntawv xa ntawv, Suav Xyoo Tshiab, cov cim kev tiv thaiv, cov cim npe pov tseg, ntau daim credit card. Tsis tas li ntawd siv nyob rau hauv dai kom zoo nkauj thiab sau ntawm ntau yam khoom. Tus qauv luam tawm yog nruam, tsis pom kev, thiab muaj kev sibtham zoo tiag tiag. Ntau-angle embossing yuav ua tau ib txhij ntawm cov pob zeb tsis zoo ntawm cov khoom tsim. Niaj hnub no, nws tseem xyaum tau ntau yam qauv xws li ntoo, yawg, agate, snakeskin, marble, thiab lwm yam, thiab nws yog qhov nyuaj rau qhov txawv qhov zoo tshaj plaws simulation nyhuv nrog cov khoom ntuj.
Raster stereo printing yog ib qho luam ntawv uas siv ib lub phaj nyom los muab duab peb sab. Cov hom ntawv no tuaj yeem soj ntsuam ib qho duab uas muaj peb sab hauv ntawm ob sab duab dav hlau yam tsis muaj cuab yeej. Saib ntawm cov khoom no, cov neeg yuav tsum xav txog seb nws tau ua li cas. Tib neeg yeej ua tau ib qho kev paub zoo txog qhov peb pom thaum pom qhov khoom vim tias muaj qee qhov nyob nruab nrab ntawm lub qhov muag ntawm tus neeg. Thaum pom ib yam khoom, sab laug thiab sab qhov muag tau pom ntawm cov ces kaum sib txawv los ua qhov muag qhov sib txawv ntawm ob lub qhov muag. Cov duab ua ntau yam yog tsim nyob rau hauv lub hlwb, thiab qhov kev txiav txim siab ntawm qhov kev ncua deb thiab peb-dimensionality yog tsim.
Cov khoom siv ua ntej siv cov ntsiab cai ntawm kev tshuaj xyuas stereoscopic siv lub cylindrical lens lub tso zis. Qhov ntawd yog, qhov kev xav hauv stereoscopic tsim los ntawm tib neeg hauv nruab nrab ntawm cov neeg txhim kho teeb meem thiab kev sib haum xeeb. Yog li, hauv txoj kev xav, duab duab stereoscopic yuav ua tau tawm los ntawm kev siv cov txheej txheem ntawm qhov chaw los ntawm ob lossis ntau dua kev soj ntsuam.
Lens cylindrical stereo grating muaj ntau hom cylindrical me me uas muaj cov yam ntxwv tsis zoo thiab cov khoom sib xws. Cov cuab yeej no muab qhov nws 'compression' thiab 'cais tawm' ntawm daim duab. Cylindrical stereo gratings tau sau ntau cov duab los ntawm ntau cov ces kaum nyob hauv lub xeev stripe rau tib daim duab. Thaum saib, tib hom cylindrical stereo grating tseem siv, kom ob lub qhov muag ntawm tib lub scene yuav pom ob lub qhov muag, thiab tom qab ntawd ces qhov tob duab uas muaj qhov sib txuam ntawm daim duab tso tawm. Lub cylindrical lens stereo grating yog tsim los ntawm ib lub cylindrical lens txheej txheem ntawm ib txoj kab. Yog li, cov duab cylindrical stereoscopic stereoscopic duab yuav tsum tau hu ua ib daim duab ntawm ib qho autostereoscopic. Lub ntsiab lus yog hais tias tsuas yog kab lus qhia txog kab rov tav parallax.
Daim duab thev duab uas ua los ntawm txoj kev kho qhov muag los ntawm cov cylindrical lens stereoscopic grating imaging kuj yog yam muaj xws li nram qab no:
1. Daim duab tso duab yuav tsum muaj cov duab uas tau muab los ntawm ntau qhov kev pom ntawm tib qho chaw. Vim yog txoj kev uas ib-thooj ib txwm siv ntawm cov grating, cov khoom rau lub sijhawm ntawm pawg duab no yuav tsum nyob ntawm qhov siab tib yam.
2. Cov duab sib xyaw duab stereoscopic yog tsim los ntawm kab txaij mus tib seem mus rau txoj kab sab nraud ntawm txoj kab ntawv sab nraud. Lub suab qij tib yam txheej txheem ntawm txhua qhov duab hauv ib pawg duab uas sib npaug zos. Raws li pom hauv daim duab! Daim duab tso duab yog tsim los ntawm ob daim duab. 3Txog ntawm qhov chaw ntawm txhua daim duab, tib qho taw tes muaj ob lub ntsiab lus nyob rau hauv daim duab tso duab, yog li ntawd qhov kev tawm mus rau qhov chaw tawm, uas yog vim li cas rau kev cuam tshuam cov tho kev nyuab siab.
Qhov loj tshaj teeb meem uas ntsib raster stereo printing yog xim sib cais platemaking vim tias cov nyhuv stereoscopic ntawm cov grating yog tau los ntawm kev sib cais thiab recombining cov duab rau hauv ib lub me raster. Lub ntsiab yog tias qhov kev cuam tshuam cov software siv cov duab. Hom ntaub ntawv no feem ntau loj heev, yuav tsum tau siv lub computer kom muaj lub hwjchim txaus los ua cov ntaub ntawv scanned. Ntxiv mus, cov yam ntxwv ntawm duab duab pixelskis duab pixels zoo thiab qhov loj ntawm qhov lenticular grating yog ntau tshaj 120 kab / cm.
Vim tias cov duab stereoscopic yog tsim muaj pixels ze ze, tom qab cov phaj ua thiab luam ntawv, lub cylindrical iav phaj tseem yuav tag nrho, yog li ntxiv rau qhov tsim ntawm lub mesh kaum, nws yog ib qho tsim nyog los xav txog tsis tsim ib vaub kib ntawm cov ntxaij vab tshaus. Lub kaum ntse ntse lub kaum ntse ntse thiab lub tshuab tsim los ntawm cov kab pixel thiab cov kab cylindrical. Hauv cov ntawv luam tawm peb-kaum, lub kaum sab xis ntawm lub cable yuav tsum tsis raug xaiv. Vim hais tias kab teeb ci kab ntawm kab rov tav yog qhov pom tseeb, thiab. 'Nws yog orthogonal rau kab pixel thiab kab sab, uas cuam tshuam nrog qhov sharpness thiab qhov tob ntawm daim duab. Tsis tas li ntawd xwb, vim yog qhov luam tawm peb lub voj voog, nws yog ib qho screen zoo 300-kab. Hauv kev luam ntawv, nws tsuas yog siv 8.5% lossis 90% ntawm lub hnub. Txwv tsis pub, nws yog ib qho yooj yim los muab tshuaj thaum sau ntawv. Qhov no yuav tsum tau nce cov xim ntawm qhov tsaus ntuj kom mus txog 9 -9.5 points. Yog li ntawd, qhov luam tawm peb lub vojvoog muaj ntau dua hauv qhov chaw tshaj li plaub-xim luam ntawv.
Qhov kev xav tau luam tawm peb lub hauv paus ntawm cov grating no yeej muaj tseeb. Tam sim no, muaj ob lub ntsiab lus luam tawm, ib qho yog ncaj qha mus sau rau ntawm cov khoom siv, thiab lwm tus yog sau rau ntawm daim ntawv thiab muab cov ntawv tso tawm rau hauv cov grating los yog paste rau ntawm cov yas yeeb yaj kiab thiab tom qab ntawd nias qhov grating. . Qhov tuab ntawm cov zuag yog nyob ntawm qhov qis 0.008 thiab 0.385 nti. Yog li, yog tias luam ntawv luam tawm tsis pub luam tawm me me, cov khoom luam tawm yuav yog ib qho pov tseg. Ib tug me me sib txawv yuav cuam tshuam rau cov nyhuv ntawm tag nrho layout. Yog li ntawd, qhov peb luam tawm ntawm cov grating muaj siab precision rau ntawm cov khoom siv luam ntawv, thiab yuam kev yuam kev yuav tsum tsawg dua 0.0lmm.
Nyob rau hauv cov ntaub ntawv ntawm ib tug post-synthesis luam ntawv rau cylindrical grating daim hlau thiab luam teeb meem, tus txheej txheem ntawm meej txuas rau daim duab mus rau grating phaj yog qhov tseem ceeb. Qee cov tuam txhab muaj kev ua haujlwm. Muaj ntau yam kev sib txuas tsis sib xws, thiab tus neeg ua haujlwm cov kev txawj ua haujlwm ncaj qha mus rau qhov zoo ntawm daim duab tso duab. Cov txheej txheem ntawm kev nplua ntawm daim phaj yog siv ib txheej ntawm cov kua nplaum rau ntawm cov khoom luam tawm, thiab cov cua sov thiab yaj cov txheej txheem thermoplastic khoom rau hauv lub cylindrical grating phaj hauv cov pwm. Lub phaj ntim txuas nrog cov ntawv luam tawm. Txoj kab kev raster yog precisely mus raws li cov kab raster ntawm daim luam kom pom qhov tshwm sim muaj peb sab. Lub suab ntawm lensicular yog 0.6 hli, thiab lub ntsiab concave thiab convex ntu faib cov duab equidistantly rau hauv ib lub priels ntawm myriad. Muaj txog 48 concave thiab convex kab ib centimeter ntawm cylindrical grating paib. Muaj li ntawm 6 pixels nram qab no txhua kab kev sib txuas thiab cov kab convex. Nws tsis yoojyim los tswj cov kev sib dhos ntawm cov nplhaib nrog cov kab zauv ntawm cov ntawv luam tawm. Cov txheej txheem luam ntawv ncaj qha luam tawm ntawm cov khoom siv yog yooj yim, thiab cov khoom tiav tau ncaj qha tau luam tawm ntev li ntev tau lub tshuab ua tiav. Txawm li cas los, tsis zoo li cov txwm luam, nws yog thaum kawg tsim nyog yuav tau thov ib txheej ntawm cov kua roj voos xim saum lub tshuab luam ntawv.
Txawm hais tias txoj kev xav ntawm stereoscopic imagery tawm tswv yim hais tias tus Tswv muaj keeb kwm ntawm tsawg tshaj 100 xyoo, qhov ua daim ntawv thov ntawm no technology tau ntev heev. Lub raster stereo luam tawm yog muab los ntawm cov duab tho kev thaij duab (three-dimensional stereoscopic film) uas tau muab los ntawm cov duab thev duab. Txawm li cas los xij, vim yog siv cov qauv kev txhim kho hauv cov qauv thiab cov khoom siv ntawm cov duab tso tawm, cov duab tso duab tsis zoo rau hauv daim ntawv thov thiab kev siab tshaj ntawm cov cuab yeej precision, cov txheej txheem kev siv tshuab nyuaj thiab cov nqi siab. Yog li no, lub duab thev naus laus zuj zus tsis tau nce thiab nrov, thiab kev tso tawm hauv lub tso suab tau raug rau kev ua yuam kev ntawm cov txheej txheem ua ntej thiab cov txheej txheem loj. Txoj kev lag luam nyuaj, tsis muaj nyiaj zoo, tsis zoo, khoom seem kev lag luam, thiab khoom kim heev tshwj xeeb khoom siv thiab khoom siv kuj yog vim li cas uas tsis tshua tawm tsam cov ntaub ntawv thiab kev tsim tawm ntawm raster stereo printing technology.
Stereoscopic photography nyob rau hauv lub xyoo pua 21st pib lub hnub nyoog digital. Tib neeg siv computer software rau ntau cov duab synthesis. Kev tsim kho ntawm kev siv computer technology, tshwj xeeb tshaj yog cov duab tawm tswv yim, kev ua haujlwm thiab kev siv zis, ua kom yooj yim rau kev sib txuas duab hauv computer-synthesized stereoscopic.
Nrog lub tswv yim ntawm lub computer-rau-phaj CTP technology, high-precision luam siv FM dots yog saws. UV kev siv tshuab txuas mus ntxiv, thiab ntau cov khoom lag luam tau ua ntau hom UV tshaj tawm xovxwm. Heidelberg, Manroland, KBA, Komori, thiab Liyoubi tau tshaj tawm presses nrog cov kev ua no. Cov tib neeg luam tawm ntawm cov ntaub ntawv pov thawj cov ntaub ntawv yas siv los ntawm kev ntaus ntawv cov tshuab luam ntawv tsis yog teeb meem. Lub tshuab luam tawm peb qhov qauv zoo tau muab pov tseg. Qhov luam tawm peb qhov ntawm gratings tau raug tsim tawm sai sai. Nyob rau hauv xyoo tas los, cov ntawv luam tawm peb lub hauv paus tau loj heev. Lub tsev luam ntawv tau pib siv cov khoom siv luam yeeb uas muag cov khoom siv kom tau ntau yam. Ntawm daim ntawv lo, cov ntawv xa mus rau cov khoom ntim khoom, thiab cov khob yas txawm, muaj ib qhov chaw zoo nkauj ntawm daim ntawv tso npe ntawm lub tso suab.
Txawm hais tias tus stereoscopic pom cov nyhuv tsis pom tiag ntawm qhov khoom, raster stereo luam ntawv tsis yog lub tswv yim rau kev ua rau me nyuam yaus. Piv nrog rau cov qauv duab thev naus laus zis, nws qhia tau hais tias nws qhov tshwj xeeb zoo tshaj plaws ntawm kev khwv nyiaj thiab kev siv. Peb ntseeg hais tias kev siv lub tshuab tho luam tawm yuav muaj qhov chaw dav dav thiab kev loj hlob nyob rau tom teb luam ntawv tom ntej. zeem muag.
