Nyob hauv kev tshuam ntawm kev luam ntawv, qhov kev luam tawm peb qhov duab ntawm peb yam duab ntawm cov khoom luam tawm - luam tawm 3-seem, tau dhau los ua cov ntsiab lus tseem ceeb hauv kev lag luam luam tshwj xeeb, cov nram qab no yuav tham txog cov qauv kev paub thiab kev txhim kho.
Cov hauv paus ntsiab lus thiab cov yeeb yam ntawm cov ntawv luam tawm peb
Lub hauv paus ntsiab lus ntawm cov ntawv luam tawm 3-dimensional yog sim kom pom qhov kev ncua deb ntawm ob lub qhov muag ntawm ib tug neeg. Los ntawm ntau cov ces kaum, sab laug thiab txoj cai pixels raug kaw rau ntawm cov khoom siv duab. Thaum saib, lub qhov muag sab laug pom sab laug pixel thiab lub qhov muag pom txoj cai pixel. Cov xwm txheej sau ua raws li lub ntsiab cai no hu ua Rau qhov luam tawm peb lub hauv paus.
Cov ntawv luam tawm peb lub hauv paus muaj cov yam ntxwv nram qab no: (1) Yam khoom muaj peev xwm rov ua tau tiag tiag, thiab muaj qhov muaj siab muaj peb sab. Cov khoom muag yog meej, cov txheej yog nplua nuj, daim duab yog qhov tseeb, thiab lub tswv yim zoo nkauj tob; (2) daim ntawv luam ntawm cov ntawv luam ntawm qhov peb sab yog feem ntau tsim los ntawm tus tsim lossis qhov chaw, thiab cov ntawv luam tawm feem ntau yog xaiv ua cov ntaub ntawv zoo thiab high-cal the luam ntawv luam, yog li cov gloss zoo. Cov xim yog ci thiab tsis yoojyim rau ploj; (3) Cov nplais ntawm cov khoom luam tawm tau them nrog ib txheej ntawm cov khoom siv hauv cov thawv thiab cov duab pleev rau sab nraud, uas tuaj yeem saib ncaj qha cov duab hauv duab panoramic. Los ntawm cov kev xav ntawm stereoscopic qhov muag ntawm cov khoom, lub qhov muag ntawm stereoscopic ntawm cov khoom yog feem ntau los ntawm tib neeg tus yam kev mob, kev paub thiab puas hlwb. Qhov tseeb tiag, lub siab lub ntsws tsis pom kev yog lub ntsiab lus ntawm cov neeg ua ke uas cov neeg ua ke los ua cov teebmeem ntawm kev txiav txim siab hauv txoj kev pom. Los ntawm kev pom ntawm lub cev, muaj cov txheej txheem (parallax) (ob sab qhov muag thiab cov lus taw qhia ua ke), kev sib yeem, thiab kev tswj hwm. Tshwj xeeb, binocular parallax yog qhov tseem ceeb rau cov tib neeg tau txais kev pom lub zeem muag. Hauv txhua txhua lub neej, thaum neeg pom ib yam khoom, tus duab ntawm qhov khoom pom los ntawm sab laug thiab sab qhov muag yuav txawv vim yog lub kaum sab xis pom ntawm ob lub qhov muag. Parallax, nws muab cov neeg ib lub ntsiab lus uas muaj peb sab.
Cov nyhuv ntawm duab duab stereoscopic yuav tsum tau pom los ntawm cov qauv siv tshuab. Lub thev naus laus zuj zus tuaj rau ntawm no yog hais txog cov ntaub ntawv tho kev thev naus laus zis ntawm cov duab, uas yog lwm qhov yooj yim rau kev nkag siab ntawm kev xav hauv stereoscopic. Muaj ob txoj hauv kev rau kev paub txog cov khoom siv duab stereoscopic, namely, ob txoj hauv kev pom thiab txoj kev ua ntau txoj hauv kev.
(1) Ob txoj kev tso duab pom. Yuav muab faib ua stereoscopic txoj kev, ob-xim lim txoj kev, polarized xim lim txoj kev thiab hloov txoj kev ua devmentation. Txawm tsis muaj hom kev saws li cas los xij, lub zeem muag ntawm stereoscopic yog tau los ntawm kev saib xyuas cov duab los ntawm kev siv qhov muag ntsia sab laug thiab sab xis. Txoj Kev Stereoscopic: Lub hauv paus ntsiab lus ntawm kev siv lub stereoscopic yog siv lub iav tsom iav kom pom cov qauv thiab sab xis kom tsim tau cov kev tshwm sim muaj peb sab. Txoj kev no tau siv ntau txij thaum lub sijhawm xyoo 19th, tab sis tshwj xeeb yuav tau siv cov stereoscopes, txwv tsis pub yuav tsis pom lub ntsws stereoscopic. Ob hom xim lim: ib txoj hauv uas sab laug thiab txoj cai yog luam tawm hauv tib lub dav hlau nrog xim liab thiab xiav inks, thiab cov duab luam tau pom los ntawm xim liab thiab xiav xim. Vim cov xim lim thiab tus cwj mem yog sib txuam ua ke, cov duab pom los ntawm cov xim lim xim tsis liab thiab xiav tab sis dub. Yog li no, hom no tsuas siv cov duab dub thiab dawb xwb thiab tsis haum rau cov xim luam yeeb. Tsis tas li ntawd, lub teeb ntawm ntau lub wavelengths nkag ob lub qhov muag, uas yog ib qho yooj yim ua rau lub qhov muag nkees. Yog li no, hom no tsis tshua siv tshwj tsis yog kev siv cov qauv ntoo. Polarized xim lim hom: Cov duab sab laug thiab txoj cai yog feem los ntawm tib lub dav hlau los ntawm kev ntxhib ntxoo xim xim tawv nqaij uas yog sib luag, thiab lub qhov muag sab laug thiab sab xis kuj tau pom los ntawm cov xim tib yam nkaus xwb. Txawm hais tias txoj cai no yuav tsum tau coj tus iav tshwj xeeb, nws tau siv rau hauv cov yeeb yaj kiab thiab cov suab paj nruag stereoscopic. Lwm txoj kev segmentation: Cov duab sab laug thiab sab xis raug muab tso rau tib lub dav hlau thiab qhov tseem ceeb ntawm tib lub sij hawm yog masked, ua li no ua rau muaj cov nyhuv stereoscopic. Txij li thaum cov nyhuv tom qab ntawd ua rau lub teeb ci ntsa iab, thiab tus nqi ntawm cov tsom iav thaiv kom siab, qhov no nws tsis tau nrov vim hais tias kom deb li deb.
(2) Cov kev coj ua ntau txoj hau kev. Muaj cov txheej txheem ntawm cov txheej txheem thiab cov cylindrical lens. Txoj kev ntsuam xyuas Parallax: Parallax shielding txoj kev, kuj hu ua parallax slit method, yog tsim los ntawm FELFOR nyob rau xyoo 1930. Nws txoj haujlwm ua haujlwm yog faib cov duab ntawm sab laug thiab cov duab ntawm lub qhov muag los ntawm txoj kab thiab tso tawm rau hauv zaj duab xis, thiab ces tsim nws . , luam tawm thiab luam ntawv. Yog tias koj tso nws rau tib txoj hauj lwm thaum lub sij hawm tua, ob lub qhov muag tseem muab tso rau ntawm qhov chaw uas tus duab muab tso rau hauv, thiab tus duab stereoscopic pom tau. Los ntawm kev ua ntawv thov cov txheej txheem hauv daim duab, yog tias ob qho duab tau muab tso ua ke, ib qho duab muab tso zis staleoscopic tuaj yeem tau txais. Yog hais tias qhov sib qis ntawm lub slit yog txo qis dua, tus synthesis ntawm ntau tshaj cov duab yuav raug ua tiav, thiab ib daim duab duab parallax panoramic tuaj yeem tau txais. Txoj kev ua haujlwm hauv txoj kab kev poob haujlwm yog qhov tseem ceeb uas tsis tshua tau pom zoo tias qhov teeb meem ntawm qhov kaj yog decremented. Yog li, nws yog tam sim no tsis tshua siv tshwj yog siv nyob rau hauv cov photography ntawm lub cylindrical lens hom. Cylindrical lens hom: Lub lens cylindrical yuav pom tau tias yog lub lens phaj uas muaj ntau tshaj li ntawm cov ntawv khawm lens ntawm ib sab, uas muaj kev cuam tshuam zoo. Sab nraub qaum ntawm lub lens coincides nrog lub dav hlau focal. Vim cov duab sib txuas ntawm lub lens, cov duab A, B, C, thiab D hauv txhua lub tsheb yuav raug cais mus rau ib, b, c, thiab d thiab kaw hauv lub focal dav hlau, tsuav yog sab laug thiab sab xis muab tso rau hauv B thiab C. Qhov chaw, koj tuaj yeem pom lub duab tso duab.
Cov txheej txheem luam ntawv thiab cov ntsiab lus
Daim ntawv thij duab "Three-dimensional printing"
Raws li tau piav saum toj no, cylindrical lens method embossing yuav tsum tau ib daim duab ntawm ib yam khoom pom los ntawm ntau cov lus qhia. Txoj kev yees duab tau muaj (1) cov lus tsa suab hauv lub suab. Txoj kev no yuav siv tus taw tes ntawm qhov khoom ua qhov chaw ntawm qhov chaw, thiab qhov kev ncua deb ntawm qhov point rau lub koob yees duab yog lub vojvoog ntawm lub nraub qaum, thiab lub koob yees duab txav raws hauv lub arc tua tsis tu ncua los sis intermittently; (2) Qhov kev daws teeb meem no.
