Imirasire ya Neural
Neural Radiance Fields (NeRF) yubaka amashusho yuzuye ya 3D uhereye kumafoto asanzwe, akwemerera kuguruka kamera muburyo bushya.
Incamake
It reframed 3D capture as training a tiny neural network rather than building a mesh.
Kwibira cyane
Yatangijwe muri 2020 na Mildenhall na bagenzi be, NeRF ibika ibintu byose imbere mumiyoboro mito mito (imyumvire myinshi). Uhaye ingingo ya 3D hamwe nicyerekezo cyo kureba, urusobe rusohora ibara ryibara nuburyo butagaragara. Kugirango utange pigiseli, NeRF irasa imirasire aho igaragara, ingero zerekana kuruhande, ibaza urusobe, kandi ihuza ibisubizo ukoresheje amajwi. Kuberako iyi nzira yose itandukanye, umuyoboro watojwe mukugereranya pigiseli yatanzwe kumafoto yukuri yinjira hanyuma ugahindura kugeza bihuye. Kwishura biratangaje gufotora, harimo n'ingaruka zishingiye kubitekerezo nko gutekereza hamwe nibintu byerekana urumuri bihinduka uko ugenda. Ikibi ni uko buri gice gikenera imyitozo yacyo, kandi uburyo bwambere bwatinze kuri gari ya moshi no gutanga.
Ubushishozi
NeRF yerekana ibintu nkibikorwa bikomeza 5D: shyiramo umwanya (x, y, z) wongeyeho icyerekezo cyo kureba (impande ebyiri), kandi MLP isubiza ibara rya RGB nubucucike bwijwi. Ikintu cyingenzi ni kodegisi ihagaze, ikarita ihuza binyuze mumikorere myinshi ya sine na cosine kugirango urusobe rushobore gufata ibisobanuro bikarishye aho kubyara umusaruro utagaragara. Gutanga bihuza ibara n'ubucucike kuri buri cyuma cyerekana kamera, uburemere bwegereye, ibyitegererezo byinshi bidasobanutse cyane, imibare yimibare ya kera yatanzwe yatojwe.
Ingaruka z'Ingamba
Umuvuduko n'igipimo
AI igaragara irashobora gukora igenzura, gutahura, no gutondekanya imirimo kurwego.
Build choices
Amakipe arema arashobora prototype ibitekerezo byihuse hamwe nintoki nkeya.
Itsinda hamwe nakazi
Ibikorwa birashobora gukoresha amashusho nibimenyetso bya videwo byari bigoye gutunganya.
Kazoza ka Neural Imirasire
Ubushakashatsi bwa NeRF bwaturikiye nyuma ya 2020, hamwe nogukurikirana nka Instant-NGP igabanya amahugurwa kuva kumasaha kugeza kumasegonda ukoresheje kodegisi ya hash-grid, na Mip-NeRF itezimbere ubuziranenge mubipimo. Umwanya uragenda uhuza cyangwa uhanganye na Gaussian Splatting, itanga vuba. Tegereza tekinike ikomoka kuri NeRF mugushushanya, kureba ibicuruzwa bya e-ubucuruzi, kwerekana amashusho yerekana amashusho, hamwe na AR / VR, hiyongereyeho kwiyongera muri NeRF ifite imbaraga zikora amashusho yimuka hamwe nifatwa rya "mu gasozi" hamwe no kumurika. Insanganyamatsiko nini ni umuvuduko, guhindurwa, no gufata amashusho kumafoto make, messier.
Gushyira mu bikorwa Isi
Guhindura videwo ya terefone yikintu muburyo bwa 3D urashobora kuzenguruka kugura kumurongo
Kongera kubaka ahantu nyaburanga nkibisobanuro byamafoto ya firime n'ingaruka ziboneka
Kubaka amashusho ya immersive ya 3D kubintu byukuri kandi byongerewe uburambe
Kubungabunga muburyo nyaburanga ndangamurage ndangamuco n'ibicuruzwa biva kumafoto
Ingaruka & Kurinda
Uburenganzira bwishusho hamwe no kwemererwa birashobora guhinduka ibyago byemewe n'amategeko niba ibimenyetso bidasobanutse.
Imikorere yicyitegererezo irashobora gutandukana kumurika, demografiya, nibidukikije.
Ibyiza byibinyoma birashobora kutamenyekana keretse niba ibyiringiro byateganijwe bikurikiranwa.
Igishushanyo mbonera
Sobanura ibipimo byo kwemererwa kugiciro, kwibutsa, nibiciro byamakosa.
Gerageza hamwe namakuru ajyanye nuburyo nyabwo bwo gukora.
Ongeraho isubiramo ryabantu kubwizere buke cyangwa guhanura cyane.
Kurikirana icyitegererezo cya drift hanyuma uhindurwe nyuma ya kamera cyangwa dataset ihinduka.

Mip-NeRF na Kurwanya Imirasire Yumurima
Ibibazo bikunze kubazwa
What is Neural Radiance Fields?
Neural Radiance Fields (NeRF) yubaka amashusho yuzuye ya 3D uhereye kumafoto asanzwe, akwemerera kuguruka kamera muburyo bushya. Yongeye kuvugurura gufata 3D nkumutoza umuyoboro muto muto aho kubaka mesh.
Niyihe ntego nyamukuru yumurima wa Neural Imirasire?
NeRF yubaka ishusho ya 3D uhereye kumurongo wamashusho, igafasha kwifotoza uhereye kubitekerezo bitari kumafoto yumwimerere.
Niki NeRF ya neural net isohoka kugirango yinjizwe?
Kubirindiro bya 3D no kureba icyerekezo, MLP isubiza ibara n'ubucucike (opacity) muricyo gihe.
Nibihe byinjira mumikorere ya 5D ya NeRF?
NeRF ifata umwanya wa 3D (x, y, z) hamwe nicyerekezo cyo kureba (impande ebyiri), zose hamwe zinjiza eshanu.
Nigute NeRF ihindura ibisubizo byayo murusobekerane rwa pigiseli ya nyuma?
Ingero za NeRF zerekana kuri buri mirasire kandi igahuza ibara ryayo riremereye nubucucike, ingano ya classique yerekana ingero yakozwe itandukanye.
Kuki NeRF ikoresha kodegisi ya posisiyo kuri enterineti?
Gushushanya ikarita ikoresheje ibikorwa byinshi bya sine / cosine ireka MLP igereranya ibisobanuro byiza aho kuba ibisubizo bitagaragara.
