Stereo xinesmas yog cov lus hais uas tau nyob ib puag ncig ntev dhau los, qee lub sijhawm nyob hauv nruab nrab ntawm xyoo nees nkaum, thiab thawj daim ntawv thov patent rau luam yeeb yaj kiab stereo tau foob thaum xyoo 1890s los ntawm William Freese-Green. Txawm li cas los xij, 3d hom ntawv tau txais qhov nrov tshaj plaws hauv peb lub caij nyoog, vim nws qhov kev cog lus loj thiab cov kev pheej hmoo ntawm kev siv.
Cov Lus Qhia

Cov yam ntxwv ntawm 3d hom ntawv yog tias cov duab thaij nrog ob lenses thiab tom qab ua tiav rau qhov pom ntawm txhua qhov muag nyias. Qhov ntim hauv peb lub siab yog pom los ntawm lub hlwb los ntawm cov hlab ntaws cov ntawm ob lub qhov muag. Yog tias koj tuaj yeem pom nrog ib lub qhov muag nkaus xwb, 3d hom ntawv yuav tsis nthuav tawm cov duab pom rau koj. Muaj ntau txoj hauv kev rau kev xa cov duab hauv ntim.

Qhov yooj yim thiab feem ntau yog anaglyph. Cov txheej txheem muaj nyob rau hauv encoding xim nrog offset rau hauv cov xim spectrum tshwj xeeb rau txhua qhov muag sib cais, piv txwv, liab thiab xiav. Ob daim duab thaij los ntawm cov ces kaum sib txawv yog npaj ua ke. Tus saib pom hnav anaglyph tsom iav nrog cov ntxaij lim dej tsim nyog, thaum txhua tus ntawm nws lub qhov muag pom tsuas yog ib feem ntawm daim duab. Qhov tsis zoo ntawm hom qauv no tsis tiav xim thiab ua kom lub teeb ci muaj zog los ntawm cov ntxaij lim dej.

Txoj kev siv kaw, los yog dab noj, teeb lub teeb. Qhov screen pauv ntawm cov duab rau ntawm sab laug thiab sab xis qhov muag. Cov kev pauv ntawm cov duab yog nqa los ntawm kev sib txuam ua ntu zuj zus ntawm cov tsom iav tsom iav, nqa nrog lub siab. Lub inertia ntawm kev pom kev ua kom pom qhov tsis meej ntawm peb lub duab. Cons - qhov hnyav ntawm lub tsom iav, qhov cuam tshuam ntawm bifurcation ntawm cov khoom txav tau nrawm dua, lub teeb nqus thaum lub tshuab kaw tau raug kaw.

Polarization txoj kev. Polarizing lim siv ntawm 90 ° rau txhua lwm. Cov taub lim dej no pom hauv cov tsom iav thiab tau hnav ntawm sab laug thiab sab qhov muag pom zoo. Ib qho tshwj xeeb silvered screen tau thov. Tsuas yog tias ib feem ntawm cov vuag voos uas tau lim los ntawm lub lo ntsiab muag ntawm lub tsom iav tau hla dhau lub khob rau sab laug thiab sab qhov muag. Cov txheej txheem hom kev cai coj los siv hauv IMAX 3D thev naus laus zis.

Lub Pulrich nyhuv yog muaj rau kev siv tsev. Nws tsis yog qhov cais raws li cov txheej txheem stereoscopic, vim nws tsis tsim cov duab rau sab laug thiab sab muag. Cov nyhuv no yog ua raws li qhov kev ncua ntawm qhov taw qhia ntawm cov hlab ntsha thaum lub ncauj lus txav mus rov qab. Koj tuaj yeem siv cov looj tsom iav qub, tshem tawm hauv qab ntawm lub lens thiab saib cov yeeb yaj kiab 2d tsis tu ncua. Thaum lub koob thaij duab lossis cov khoom txav mus, qhov kev cuam tshuam peb-seem yuav raug tsim. 3d cov ntxaij lim dej player uas cog lus tias yuav ua ib qho kev ua yeeb yaj kiab zoo saib peb ntu siv tib lub ntsiab cai. Daim duab yog qeeb rau ntawm ib lossis ntau daim thav ntawv, tom qab ntawd hloov mus ua anaglyph lossis shutter tus qauv hauv lub sijhawm. Qhov tsis zoo ntawm cov nyhuv Pulrich yog qhov xwm txheej zoo li qub tsis tsim cov duab peb qho.
