Ubi Radiance Neural
Neural Radiance Fields (NeRF) na-ewughachi ọnọdụ 3D zuru oke site na foto nkịtị, na-ahapụ gị ka ị fega igwefoto gaa n'ọhụụ ọhụụ.
Nchịkọta
It reframed 3D capture as training a tiny neural network rather than building a mesh.

Ewebata na 2020 site n'aka Mildenhall na ndị ọrụ ibe ya, NeRF na-echekwa ọnọdụ niile n'ime obere netwọkụ akwara ozi (perceptron multilayer). Nyere isi ihe 3D na ntụzịaka nlele, netwọkụ ahụ na-ewepụta agba ebe ahụ yana etu o siri dị. Iji nye pikselụ, NeRF na-agbaba ụzarị n'ime ihe nkiri ahụ, tụọ ihe atụ n'akụkụ ya, jụọ netwọkụ ahụ, wee gwakọta nsonaazụ ya site na iji ntụgharị olu. N'ihi na usoro a niile nwere ike ịdị iche, a na-azụ netwọk ahụ site n'iji pikselụ atụnyere foto ndenye n'ezie na ịhazigharị ruo mgbe ha dakọtara.

What is Neural Radiance Fields?
Neural Radiance Fields (NeRF) na-ewughachi ọnọdụ 3D zuru oke site na foto nkịtị, na-ahapụ gị ka ị fega igwefoto gaa n'ọhụụ ọhụụ. Ọ meziri njide 3D ka ọ na-azụ obere netwọkụ akwara kama iwulite ntupu.
Kedu ihe bụ isi ebumnuche nke Ubi Radiance Neural?
NeRF na-ewulite ihe nnochi anya 3D site na onyonyo onyonyo, na-eme ka ntụgharị foto dị adị site n'echiche ọ bụghị na foto mbụ.
Kedu ihe NeRF netwọk neural na-emepụta maka ntinye enyere?
Maka ọnọdụ 3D na ntụzịaka nlele, MLP na-eweghachi agba na njupụta (opacity) n'oge ahụ.
Kedu ihe ntinye na ọrụ 5D NeRF?
NeRF na-ewere ọnọdụ 3D (x, y, z) yana ntụzịaka nlele (akụkụ abụọ), na-agbakọta ntinye ise.
Kedu ka NeRF si atụgharị mmepụta netwọk ya ka ọ bụrụ agba pixel ikpeazụ?
Ihe nlele NeRF na-atụ aka n'akụkụ ụzarị ọ bụla wee jikọta ụcha ha nke njupụta dị arọ, nhazi ụda oge gboo mere ka ọ dị iche.
Kedu ihe kpatara NeRF ji eji ntinye ọnọdụ na nhazi ntinye?
Nhazi nke eserese site na ọrụ sine/cosine dị elu na-eme ka MLP nọchite anya nkọwa zuru oke kama nsonaazụ na-adịghị ahụkebe.
