1. Binocular parallax stereoscopic zaub

Binocular parallax stereoscopic cov cuab yeej siv tshuab coj cwj pwm ntawm lub hauv paus ntsiab lus ntawm tib neeg qhov muag. Thaum tib neeg qhov muag saib cov khoom, lawv yuav tau txais ob qho duab me ntsis (3D duab ua khub) vim qhov txawv ntawm ob lub qhov muag. Ob cov dluab nrog tib neeg lub hlwb fusion yuav tsim qhov kev txiav txim siab nrug, qhov tob kev xav thiab qhov kev txiav txim siab peb sab. Vim li no, siv tshuab thev naus laus zis nruab rau hauv qhov nruab nrag / duab xis ntawm cov duab ntawm sab laug lub qhov muag / lub qhov muag ntsia ntawm ntau qhov kev siv tshuab, thiab 3D duab tau los ntawm lub fusion ntawm tib neeg lub hlwb 3D duab khub. Lub tshuab dual lub tso suab stereoscopic cov cuab yeej muab faib tau rau kev siv tshuab stereoscopic thiab cov khoom siv tshuab dawb stereoscopic, raws li seb lub koom haum twg yuav tsum tau txais cov duab 3D.


1.1 Cov cuab yeej siv tshuab thev naus laus zis

Kev siv lub tshuab tho kev thev naus laus zis feem ntau yuav tsum tau siv qhov muag ntawm sab laug qhov muag / lub qhov muag kom pom tseeb rau sab laug qhov muag / qhov muag nrog kev pab los ntawm 3D iav los yog kaus mom hlau. Ntawm lawv, 3D iav yuav muab faib ua peb hom: chromatic aberration, polarized lub teeb thiab shutter. Cov kev sib raug zoo technology yog hu ua xim txawv lub tshuab thev naus laus zis, kev siv lub tshuab thev naus laus zis thiab kev siv lub tshuab thaij duab tso tawm. Xim lub duab tso xim duab muag siv xim liab thiab ntsuab (los yog xiav thiab xim liab) ob lub xim complementary tso tawm tib lub sijhawm, xim 3D tsom iav rau sab laug thiab txoj cai lim tau nqhis teeb ntawm qhov ntxeev duab, kom lub qhov muag sab nrauv / 3D cov dluab ntawm txoj cai qhov muag tau raug xa mus rau sab laug / sab xis.

Polarized stereoscopic zaub siv tshuab polarized polarization taw qhia perpendicular rau sab laug thiab txoj cai qhov muag pom tshwm tib lub sij hawm, polarized 3D tsom iav rau sab laug thiab txoj cai nrog cov kev coj ntawm polarization tso cai rau tsuas yog ib qho ntawm lub teeb dhau, kom cov duab ntawm 3D duab laug laug / txoj cai duab tau raug xa mus rau sab laug / sab xis. Lub koob yees duab ntawm cov kauj vuam siv hauv LCD siv rau kev siv duab thev naus laus zis. Thaum cov kua siv lead ua kua, nws tuaj yeem thaiv qhov teeb meem ntawm lub tsom iav. Nyob rau hauv cov lus, cov duab qhia txog cov duab sab laug / sab xis, thiab synchronizes lo ntsiab muag los rau qhov muag lo lus siv qhov voltage, kom qhov lauj lauj cai / laug muag nyob hauv ib qho kev siv opaque alternately, kom sab laug qhov muag / lub qhov muag tsuas tau txais qhov muag ntawm lub qhov muag / qhov muag. Lub kaus mom hlau txuas nrog stereoscopic cov tshuab siv ob lub teeb me me ntawm cov lus qhia kom pom cov duab 3D duab, thiab cov duab loj loj los ntawm qhov muag, thiab ua cov teeb meem zoo ib yam. Vim qhov muag qhov muag / qhov muag qhov muag sib haum mus rau sab laug qhov muag / qhov muag, 3D dluab tau tsim los ntawm tib neeg lub hlwb fusion. Txawm hais tias kev pabcuam kev thev naus laus zis los ntawm kev pabcuam thev naus laus zis, yog qhov ua tau zoo tshaj plaws thiab thev naus laus zuj zus, yog qhov tsis zoo los ntawm tsom iav los yog cov kaus mom kom tsis txhob ua ntxiv rau kev siv technology, thiab ua rau cov neeg tshawb xyuas tig rau kev tshawb fawb ntawm autostereoscopic zaub technology.


2. Kev siv lub tshuab thev naus laus zis dawb

Kev siv tshuab dawb stereoscopic tuaj yeem xa daim duab qhov muag / qhov muag qhov muag mus rau sab laug qhov muag / lub qhov muag tsis siv cov khoom pab xws li tsom iav los yog kaus mom hlau, yog li nws tseem hu ua lub qhov muag pom qhov muag 3D.

Cov tshuaj dawb tshuaj stereoscopic cov cuab yeej siv tau muab faib ua cov ntawv parallax thiab hom tshuab xais phaj plab dawb thev naus laus zis.


Raws li tau qhia hauv daim duab 1, ib daim duab ntawm daim duab tso tawm ntawm lub tshuab hlwb hlau thev naus laus zis. Cov duab pixels tso saib khib txawm khawm ntawm qhov muag, lub LCD npo muab tso rau hauv pem hauv ntej ntawm laj kab laj kab, monocular observer pom ib sab ntawm cov pixels ntawm cov lus los ntawm ib qho zis xwb qhov kev sib tw / qhov pixel kawg tsuas tau txais los ntawm lub hlwb thiab sab laug / lub qhov muag fusion 3D duab.

Vim kev siv parallax baffles, qhov luminance thiab fais fab siv ntawm cov khoom seem zoo heev. Kuj vim hais tias siv khib thiab sab suam pixels los tso saib cov dluab laug thiab txoj cai cais ua rau lub rooj ntawm 3D duab tsuas yog ib nrab ntawm pixel ntawm cov khoom vaj huam sib luag thaum nws tshwm rau hauv 2D. Tsis tas li ntawd, vim hais tias tsuas pom ib nrab ntawm pixel pom qhov kev soj ntsuam, nws yuav tsim muaj laj kab nyom.

Daim duab 2 qhia tau hais tias daim phiaj xwm txheej ntawm ntau qhov pom ntawm parallax baffle dawb stereoscopic zaub technology. Yuav kom tau 3D dluab ntawm ntau qhov chaw (nrog rau ntau yam 3D views), txhua slit yuav tsum sib cam rau ntau kab (ntau dua ob kab) pixels, yog li qhov daws teeb meem ntawm 3D cov duab ntxiv lawm.


Tsis tas li xwb, qhov chaw parallax baffle baffle area feem ntau nce, yuav ua kom cov duab ci ci thiab hwj huam noj ntxiv. Yuav kom nce qhov kev daws teeb meem ntawm 3D duab, nws yog ib qhov tsim nyog yuav txo qhov loj ntawm lub slit, uas yuav ua rau lub diffraction nyhuv thiab yuav ua rau txo cov duab zoo. Nws tuaj yeem pom tau hais tias muaj kev txwv kev sib nrauj ntawm kev daws teeb meem thiab tus naj npawb ntawm cov ces kaum qhov muag ntawm daim duab tso tawm stabble dawb tso tawm.

Daim duab 3 qhia tau hais tias daim duab ntawm lub cylindrical lens yam dawb duab stereoscopic zaub.

Raws li pom hauv daim duab 3, khib nyiab thiab sab suam pixels tso rau sab laug thiab sab qhov muag ntawm lub vijtsam duab. Lub hauv ntej ntawm daim duab yog txuas nrog lub lens micro, thiab lub dav hlau duab ntawm lub LCD vaj huam sib luag nyob rau ntawm lub dav hlau focal ntawm lub lens.

Vim hais tias qhov kev hloov ntawm lub lens unit, lub teeb yog coj mus rau hauv ib qho chaw soj ntsuam, yog li ntawd lub qhov muag pom tau tsuas yog pom ib sab ntawm pixels ntawm cov duab tso tawm los ntawm lens lens.

Thaum kawg, lub teeb uas tawm los ntawm qhov khib / kheej pixels tsuas yog tau txais los ntawm sab laug / sab xis. Tom qab ntawd lub 3D duab tau los ntawm fusion ntawm tib neeg lub hlwb. Vim tias tag nrho lub teeb tau txais los ntawm lub qhov muag los ntawm lub lens, cov duab ntawm ci ntsa iab tsis raug cuam tshuam. Txawm li cas los xij, qhov sib tw ntawm cov duab tso nrog micronens yog qhov nyuaj, thiab tseem muaj teeb meem ntawm qhov kev sib tshuam ntawm cov duab ntawm sab laug thiab sab xis. Tsis tas li ntawd, txoj kev siv cov tshuab thev naus laus zuj zus yog qhov tshwm sim ntawm kev sib nrauj thiab cov nyhav ntawm qhov kev daws teeb meem ntawm cov kev daws teeb meem thiab cov naj npawb ntawm kev xav.
