I-Neural Radiance Fields (NeRF) yakha kabusha isigcawu se-3D esigcwele sisuka ezithombeni ezimbalwa ezijwayelekile, ezikuvumela ukuthi undizise ikhamera iye emibonweni emisha sha. Ifake kabusha ukuthwebula kwe-3D njengokuqeqesha inethiwekhi encane ye-neural kunokwakha i-mesh.

I-Neural Radiance Fields ingeyokugeleza kokusebenza kombono wekhompuyutha ohumusha noma okhiqiza imidiya ebonakalayo ukuze ihlaziywe, isebenze, futhi isungule.

I-Deep Dive

Yethulwe ngo-2020 nguMildenhall nozakwabo, i-NeRF igcina yonke indawo yesehlakalo ngaphakathi kwenethiwekhi encane ye-neural (i-multilayer perceptron). Uma kunikezwe iphoyinti le-3D nendlela yokubuka, inethiwekhi ikhipha umbala walelo phuzu nokuthi i-opaque kangakanani. Ukuze inikeze iphikseli, i-NeRF idubula umsebe endaweni, isampula ikhomba eduze kwayo, ibuze inethiwekhi, futhi ihlanganise imiphumela isebenzisa ukunikezwa kwevolumu. Ngenxa yokuthi yonke le nqubo iyakwazi ukuhlukaniswa, inethiwekhi iqeqeshwa ngokuqhathanisa amaphikseli anikeziwe nezithombe zokufakwayo zangempela futhi ilungiswe ize ifane. Inzuzo i-photorealism emangalisayo, okuhlanganisa imithelela encike ekubukeni efana nokuboniswa nokugqama okucwebezelayo okushintshayo njengoba uhamba. Okubi ukuthi isigcawu ngasinye sidinga ukuqeqeshwa kwaso, futhi indlela yasekuqaleni yayihamba kancane ekuqeqesheni nasekunikezeni.

I-Technical Insight

I-NeRF imele isigcawu njengomsebenzi we-5D oqhubekayo: faka indawo (x, y, z) kanye nendawo yokubuka (ama-engeli amabili), futhi i-MLP ibuyisela umbala we-RGB nokuminyana kwevolumu. Umniningwane obalulekile umbhalo wekhodi wendawo, ohlanganisa amamephu ngokusebenzisa imisebenzi ye-sine ye-high-frequency kanye ne-cosine ukuze inethiwekhi ithwebule imininingwane ecijile esikhundleni sokukhiqiza okukhiphayo okufiphele. Ukunikezwa kuhlanganisa umbala nokuminyana emisebeni yekhamera ngayinye, ukulinganisa eduze, amasampuli afiphele kakhulu kakhulu, ngqo izibalo zokunikezwa kwevolumu yakudala ezenziwe zaqeqesheka.

I-Mastering Neural Radiance Fields

I-Neural Radiance Fields (NeRF) yakha kabusha isigcawu se-3D esigcwele sisuka ezithombeni ezimbalwa ezijwayelekile, ezikuvumela ukuthi undizise ikhamera iye emibonweni emisha sha. Ifake kabusha ukuthwebula kwe-3D njengokuqeqesha inethiwekhi encane ye-neural kunokwakha i-mesh. I-Neural Radiance Fields ingeyokugeleza kokusebenza kombono wekhompuyutha ohumusha noma okhiqiza imidiya ebonakalayo ukuze ihlaziywe, isebenze, futhi isungule. Ukuze wakhe ukuqonda okujulile, phatha i-Neural Radiance Fields njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho uhlelo olungakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.

Empeleni, amaqembu aqinile asebenzisa ukunemba kwebhalansi ye-Neural Radiance Fields namaqiniso okusebenza njengekhwalithi yedatha, ukuhluka kokukhanya, nokuvumelana kwamalebula. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.

I-Visual AI ingakwazi ukuhlola, ukutholwa, nokumaka imisebenzi esikalini. Ngesikhathi esifanayo, amalungelo ezithombe kanye nemvume kungaba ubungozi bomthetho uma ukutholakala kungacacile. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.

Ikusasa Lezinkambu Ze-Neural Radiance

Ucwaningo lwe-NeRF luqhume ngemva kuka-2020, nokulandelwa okufana nokuqeqeshwa kokusika i-Instant-NGP kusuka emahoreni kuya kumasekhondi kusetshenziswa amakhodi wegridi ye-hash, kanye ne-Mip-NeRF ithuthukisa ikhwalithi kuzo zonke izikali. Inkambu iya ngokuya ihlanganiswa noma iphonselwa inselelo yi-Gaussian Splatting, enikezela ngokushesha. Lindela amasu asuselwe ku-NeRF ekwenzeni imephu, ukubukwa komkhiqizo we-e-commerce, imiphumela yokubuka yefilimu, ne-AR/VR, kanye nokukhula kwama-NeRF ashukumisayo aphatha izigcawu ezinyakazayo kanye nokuthwebula "endle" ngokushintsha ukukhanya. Amatimu amakhulu isivinini, ukuhleleka, nokuthwebula izigcawu ezivela ezithombeni ezimbalwa, ezilula.
