Ibirahuri bya 3D, bizwi kandi nka "ibirahuri bya stereoskopi," ni ibirahuri bidasanzwe bishobora gukoreshwa mu kureba amashusho cyangwa amashusho ya 3D.Ibirahuri bya stereoskopi bigabanijemo ubwoko bwinshi bwamabara, ibisanzwe ni ubururu butukura nubururu butukura.
Igitekerezo nukwemerera amaso yombi kubona imwe gusa mumashusho abiri yishusho ya 3D, ukoresheje inzira yumucyo muburyo butandukanye kandi butandukanye.Filime ya 3D iragenda ikundwa cyane nabayireba.Kugeza ubu, hari ubwoko butatu bwibirahure bya 3D kumasoko: aberrasi ya chromatic, polarizing hamwe nigihe gito.Ihame nuko amaso yombi yakira amashusho atandukanye, kandi ubwonko buzahuza amakuru kuva kumpande zombi kugirango habeho ingaruka-eshatu.
Imiterere ya ibirahure bya 3D
Umuhengeri urumuri ni electromagnetic wave, electromagnetic wave ni shear wave, shear wave vibration icyerekezo hamwe nicyerekezo cyo gukwirakwiza ni perpendicular.Kumucyo usanzwe ukwirakwira mucyerekezo runaka, icyerekezo cyacyo cyo kunyeganyega kiboneka mubyerekezo byose byindege ihanamye yerekeza.Niba, iyo kunyeganyega hamwe nicyerekezo kimwe gusa byitwa umurongo uhindagurika muri iki gihe, uburyo umurongo munini wumurongo uhindagurika, firime ya polarisiyoneri nuburyo bworoshye cyane, hagati ya firime ya lens ya firime irimo udukoni duto duto twa kristu, itunganijwe neza muburyo bumwe, kugirango ubashe gushyira urumuri rusanzwe kugirango ruhindurwe mumaso yacu.Nka:
Ihame ryibirahure bya 3D polarize ni uko ijisho ryibumoso nijisho ryiburyo ryibirahuri bifite ibikoresho bya polariseri ihindagurika hamwe na polarizari ndende.Muri ubu buryo, iyo firime ikozwe hifashishijwe ikoranabuhanga ryumucyo ucuranzwe, ishusho yinzira yibumoso iyungurura binyuze muri transvers polarizer kugirango ibone urumuri runyuranye, kandi ishusho yinzira iburyo irayungurura binyuze mumashanyarazi maremare kugirango ibone urumuri rurerure.
Gukoresha uyu mutungo wumucyo ukabije nibyo rwose cinema ya stereoskopique ikeneye - kugirango amaso yiburyo n'ibumoso asa atandukanye rwose.Mugukoresha ibikoresho bibiri hamwe na polarizeri, umushinga utegura umushinga wuzuye urumuri rwumucyo utambitse kuri mugenzi we, hanyuma abareba barashobora kubona amaso yiburyo n'ibumoso ya mugenzi wabo bitabangamiye ibirahuri byihariye.
Mubihe byashize, ibirahuri bya 3D bya polarize byari bisizwe gusa na polarisiyasi hejuru yikirahure gisanzwe kugirango ikore firime ya polarisiyasi, yari ihendutse cyane.Ariko ubu buryo bufite inenge, mugihe ureba firime kugirango yicare neza, ntishobora gutumbagira umutwe, bitabaye ibyo izikuba kabiri.Noneho, iyo ureba firime ya 3D, lens ya polarizing yambarwa nabayireba ni polarizeri izenguruka, ni ukuvuga ko imwe isigara ihindagurika kandi indi ikaba iburyo bwa polarisiyasi, ibyo bikaba bishobora kandi gutuma amaso y’ibumoso n’iburyo abayireba babona amashusho atandukanye, kandi niyo yaba yunamye umutwe, nta kureba kabiri.
Gusobanura ibyiciro
Uburyo butandukanye bwamabara nuburyo buhendutse bwo kureba firime.Igikoresho cyo gukinisha kizerekana amashusho ibumoso n'iburyo mu mabara atandukanye (umutuku n'ubururu birasanzwe).Hamwe n'ibirahure, ijisho ry'ibumoso rishobora gusa kubona ishusho y'Ibara (nk'itara ritukura) kandi ijisho ry'iburyo rishobora gusa kubona ishusho y'ibara rya B (nk'urumuri rw'ubururu), kugira ngo tumenye uburyo butatu bwerekana ishusho y'amaso y'ibumoso n'iburyo.Ariko iyo ibara ryegereye akayunguruzo gatukura ntikarangira cyangwa akayunguruzo k'ubururu katarangiye, hazaba igicucu kabiri, biragoye kugira ingaruka nziza.Igihe kinini nyuma yijisho naryo rizatera igihe gito ivangura ryamabara ryatewe nimbogamizi.
Ubwoko bwa shutter bugerwaho muguhindura hagati yibumoso niburyo bwamaso kugirango ugere kubikorwa bya 3D.Bitandukanye na polarizing, uburyo bwo gufunga ni tekinoroji ya 3D ikora.Shitingi ya 3D ikinisha izahindura cyane hagati yijisho ryibumoso nijisho ryiburyo.Nukuvuga ko, icyarimwe, ishusho ya polarize ya 3D ikubiyemo amashusho ibumoso n'iburyo icyarimwe, ariko ubwoko bwa shitingi busigara gusa ibumoso cyangwa iburyo, kandi ibirahure bya 3D bihindura amaso yibumoso niburyo icyarimwe.Iyo ecran yerekana ijisho ryibumoso, ibirahuri bifungura ijisho ryibumoso bugafunga ijisho ryiburyo;Iyo ecran yerekana ijisho ryiburyo, ibirahuri bifungura ijisho ryiburyo bugafunga ijisho ryibumoso.Kuberako umuvuduko wo guhinduranya ari mugufi cyane kurenza igihe gito cyerekezo cyabantu, ntibishoboka kumva uhindagurika kwishusho mugihe ureba firime.Ariko tekinoroji ikomeza umwimerere wumwimerere wigishusho, bigatuma byoroha kubakoresha kwishimira HD yuzuye yuzuye 3D itabangamiye ubwiza bwishusho.
