Raws li peb txhua tus paub, lub ntiaj teb tiag tiag yog qhov chaw peb sab. Tsuas yog rau qhov ntev ntawm lub sijhawm, lub ntiaj teb tiag muaj peb qhov ntev: qhov ntev, qhov dav, thiab qhov siab. Peb nyob hauv lub ntiaj teb peb-dimensional no txhua txhua hnub, thiab feem ntau ntawm cov khoom siv uas twb muaj lawm tuaj yeem tso tawm cov ntaub ntawv ob sab xwb tsis ua rau tib neeg muaj qhov tseeb peb-dimensional. Txhawm rau ua kom cov khoom tso tawm thiab cov xwm txheej muaj kev nkag siab tob (uas yog, 3D), tib neeg tau ua kev tshawb fawb ntawm 3D zaub technology. Tom qab ntau tshaj li ob xyoos ntawm txoj kev loj hlob, cov txiaj ntsig tau zoo heev tau ua tiav.
Cov iav 3D tsis pub dawb yog siv dav hauv ntau yam xws li kev tshaj tawm, kev tshaj tawm, kev qhia ua qauv qhia, kev nthuav qhia, thiab zaj duab xis thiab TV. Sib txawv ntawm cov tsoos binocular 3D zaub thev naus laus zis, qhov muag liab qab 3D zaub muaj nws cov yam ntxwv ntawm qhov muag liab qab, uas yog, cov neeg tuaj saib tsis tas yuav tsum hnav tsom iav lossis kaus mom hlau saib cov nyhuv 3D, thiab nws qhov tseeb ntawm qhov tob thiab peb. -dimensional impression zoo heev txhim kho cov neeg tuaj saib. Qhov pom kev cuam tshuam thiab immersion thaum lub sij hawm saib tau dhau los ua cov khoom lag luam zoo tshaj plaws rau cov khoom lag luam, kev tshaj tawm pej xeem thiab kev tshaj tawm video.
Txawm li cas los xij, ua li cas cov neeg saib pom 3D yam tsis hnav cov khoom siv?
1. Cas qhov muag liab qab perceives 3D
Lub ntiaj teb tiag yog lub ntiaj teb peb-dimensional. Cov duab pom los ntawm tib neeg lub qhov muag thaum saib cov khoom muaj qhov sib txawv sab. Qhov sib txawv ntawm ob daim duab yog hu ua disparity/parallax. Nws yog qhov parallax no uas ua rau tib neeg paub qhov txawv ntawm qhov deb ntawm cov khoom thiab tau txais txiaj ntsig peb-dimensional. Raws li qhov sib txawv parallax qhov tseem ceeb, parallax tuaj yeem muab faib ua qhov zoo parallax, tsis zoo parallax thiab xoom parallax. Thaum cov neeg tuaj saib, qhov zoo parallax ua rau tib neeg xav tias cov khoom sib sib zog nqus rau hauv qhov screen; tsis zoo parallax ua rau tib neeg xav tias cov khoom yog ntab sab nraum qhov screen; xoom parallax yog ciam teb ntawm qhov zoo thiab tsis zoo parallax, thiab cov khoom tsuas yog npaj rau ntawm qhov screen, uas yog, peb feem ntau hais tias xoom dav hlau. Thaum lub caij ntuj sov hmo ntuj, cov hnub qub nyob deb ntawm peb. Txoj kab ntawm kev pom peb saib cov hnub qub yuav luag sib luag. Lub sijhawm no, tus parallax yog ze rau xoom. Nws yog ib qho nyuaj rau tib neeg lub qhov muag kom paub qhov txawv ntawm qhov deb ntawm lub hnub qub. Yog li ntawd, peb xav tias cov hnub qub nyob deb ntawm peb. Peb-dimensional.
Tib neeg lub paj hlwb yog ib tug heev complex paj hlwb. Nws tuaj yeem tsim qhov kev xav peb-dimensional los ntawm fusion kev xav ntawm lub paj hlwb optic thiab pom kev puas siab puas ntsws teb ntawm ob lub duab parallax pom hauv ob lub qhov muag. Siv lub hauv paus ntsiab lus no, peb tuaj yeem tso ob sab laug thiab sab xis duab nrog parallax ntawm tus saib thiab xa lawv mus rau sab laug thiab sab xis ob lub qhov muag raws li tau txais 3D kev xav.
Lub hauv paus ntsiab lus ntawm qhov muag liab qab 3D zaub feem ntau yog faib cov duab tso rau ntawm cov zaub los ntawm grating lossis lens, kom tib neeg lub qhov muag tuaj yeem tau txais cov duab sib txawv, yog li paub txog 3D zaub. Lub slit grating zaub tshuaj ntsuam cov ntsiab lus tso tawm los ntawm kev tso ib txoj hlua nrog qhov tsim nyog rau pem hauv ntej ntawm lub vaj huam sib luag. Tom qab ib qho kev ncua deb, lub teeb ncav cuag tib neeg lub qhov muag tuaj yeem sib cais, thiab ob lub qhov muag tau txais ob daim duab nrog parallax. Hauv daim duab 1, tib neeg lub qhov muag tuaj yeem pom xiav thiab ntsuab feem, uas tuaj yeem tsim cov nyhuv peb sab.
