Hav txhua tus, Hauv Cov Lus Qhia no, Kuv yuav qhia koj cov txheej txheem ntawm yuav ua li cas thiaj tsim 3D qauv siv cov duab digital. Cov txheej txheem hu ua Photogrammetry, tseem hu ua Image-Based Modeling (IBM). Tshwj xeeb, hom txheej txheem no yog siv los tsim dua ib qho khoom lossis chaw nyob hauv peb-seem. Los ntawm cov khoom cuav thiab ua haujlwm ntawm daim duab mus rau thaj chaw xws li thaj chaw geological thiab kev puas tsuaj, Kuv yuav los qhia yuav ua li cas thiaj tsim tau tus qauv 3D Portraiture animation thiab qhia txog kev ua haujlwm uas xav tau kom ua tiav hom kev muaj tswv yim no.

Kauj ruam 1: Software

Ua ntej, tau txais cov software xav tau los tsim 3D qauv los ntawm cov duab. Qhov no suav nrog:

Visual SFM -

Tom ntej no yog rov tsim kho tus qauv 3D. Qhov no suav nrog:

Meshlab -

Thaum kawg, kev txhim kho zaum kawg siv lwm cov software xws li:

Maya (tus tub ntxhais kawm ntawv lossis sim dawb), Blender, lossis ib qho qauv 3D qauv

Kauj Ruam 2: Duab rau VisualSFM

Tam sim no koj muaj koj li software, tawm mus thiab ntes cov duab nyoos ntawm txhua yam khoom lossis chaw lossis ib puag ncig. Muaj ob txoj hauv kev uas koj tuaj yeem ntes cov duab rau 3D qauv:

Ib txoj hauv kev yog ua tib zoo tig ncig lub hom phiaj lossis qhov chaw hauv qhov sib txuam nrog txhua kauj ruam thiab thaij duab.

Txoj hauv kev thib ob yog siv cov vis dis aus thiab tig ncig lub hom phiaj lossis chaw. Tom qab ntawd nkag mus rau Adobe Media Encoder thiab hlais cov vis dis aus rau hauv tus kheej. Pom tseeb, ntau lub thav duab koj lub koob yees duab tua hauv cov khoom siv ntau dua uas koj tuaj yeem tau txais, yog li xav paub ntau ntxiv hauv koj qhov kev ntes 3D.

Hauv VisualSFM:

1. Cov Ntaub Ntawv - Qhib+ Ntau Cov Duab (Nov yog qhov uas koj coj koj cov thav duab lossis duab tseem ceeb thiab ntshuam lawv rau hauv VisualSFM)

2. Tam sim no koj muaj tag nrho koj cov duab tso tawm, mus tom ntej thiab nyem rau ntawm Compute Missing Matches khawm. Nws yog lub pob uas muaj 4 xub taw qhia rau sab nraud. Cov txheej txheem no yuav siv sijhawm ntev nyob ntawm seb muaj pes tsawg daim duab uas koj tau muab tso rau. Qhov laj thawj yog vim li cas nws thiaj siv sijhawm ntev npaum li cas yog qhov software sib piv txhua daim duab rau lwm cov duab uas koj tau muab tso, sib piv cov ntsiab lus zoo ib yam thiab cov yam ntxwv txhawm rau txhawm rau pib ua cov txheej txheem rov tsim dua tshiab, yog li thov ua siab ntev.

3. Thaum cov txheej txheem ntawd tiav, mus tom ntej thiab nyem rau ntawm Compute 3D Reconstruction khawm. Nws yog lub pob uas zoo li khawm nrawm rau pem hauv ntej tab sis tsis muaj qhov ntxiv (nws yog sab xis ntawm Compute Missing Matches khawm). Nov yog qhov uas VisualSFM siv qhov tseem ceeb nrog cov yam zoo sib xws ntawm ib leeg thiab pib tsim 3D qauv ntawm qhov chaw lossis khoom lossis tus kheej. VisualSFM txiav txim siab cov ntaub ntawv nyoos raws li qhov nrug thiab qhov tob ntawm cov ncauj lus koom nrog hauv txhua daim duab, qhov ntawd yog li cas nws thiaj tuaj yeem rov tsim cov ntsiab lus hauv nqe lus nug ua qauv 3D. Yog vim li cas nws thiaj li hu ua VisualSFM (Structure From Motion) yog tias SfM txheej txheem sib piv cov duab ob-seem thiab kwv yees cov qauv peb-seem (qauv 3D).

4. Tom qab ntawd ua tiav, mus tom ntej thiab nyem rau ntawm CMVS rau kev tsim kho kom ntom ntom. Qhov no yuav ua tiav koj cov qauv 3D thiab koj xav khaws cov.cmvs cov ntaub ntawv thiab.nvm cov ntaub ntawv ntxiv rau cov ntawv.ply Koj yuav xav tau cov ntaub ntawv.nvm rau Meshlab thiab koj yuav xav tau cov ntawv.ply kom tau txais 3D mesh ntawm koj cov khoom lossis mesh uas tseem yuav tshwm sim hauv Meshlab.
