Optical Imaging: Capturing Txhua Qhov Ncauj Lus ntawm Qhov Ncauj Qhov Ncauj
Lub hauv paus ntawm ib qho intraoral scanner nyob rau hauv nws qhov kev pom zoo kho qhov muag. Nws ceev ceev ceev cov duab siab - daws teeb meem ntawm lub qhov ncauj kab noj hniav siv lub koob yees duab me me thiab cov teeb pom kev tshwj xeeb (xws li lub teeb xiav lossis lasers). Cov duab no tsis tsuas yog kom meej meej ntes cov duab ntawm cov hniav thiab cov pos hniav tab sis kuj sau cov ntaub ntawv hloov maj mam thiab xim. Thaum lub sij hawm luam theej duab, lub cuab yeej txuas ntxiv ntes cov duab ntawm kaum tawm thav duab ib ob, kom ntseeg tau cov ntaub ntawv tiav thiab tsis muaj kev cuam tshuam.
3D Modeling: Khawv koob los ntawm dav hlau mus rau khoom
Point Cloud Generation: Txhua daim duab 2D tau hloov pauv mus rau ntau lab ntawm cov ntsiab lus sib koom ua ke.
Surface Reconstruction: Algorithms cia li txuas cov ntsiab lus nyob ib sab los tsim cov duab peb sab mesh.
Cov ntaub ntawv Fusion: Ntau-lub kaum sab xis scan cov txiaj ntsig tau ntse txuas ua ke, tshem tawm qhov sib tshooj thiab qhov muag tsis pom.
Tag nrho cov txheej txheem yog zoo li "sculpting" ib tug meej replica ntawm tus neeg mob lub qhov ncauj kab noj hniav nrog ib tug digital paintbrush, ua tiav qhov tseeb txog li 20 micrometers.
Tiag - Sijhawm Kev Sib Txuas Lus: Ua Scanning yooj yim thiab ua tau zoo
Niaj hnub nimno intraoral scanners muab "qhov koj pom yog qhov koj tau txais" cov neeg siv kev paub. Raws li tus kws kho mob txav qhov kev sojntsuam, lub vijtsam qhia txog 3D qauv tsim cov txheej txheem nyob rau lub sijhawm, thiab lub kaw lus muab lub suab lossis kev vibration ceeb toom rau thaj chaw tsis tiav. Qee cov khoom siv kuj tseem muaj cov kev hloov kho ntse, uas tuaj yeem them nyiaj rau qhov ua yuam kev los ntawm tus neeg mob me ntsis txav, txhim kho kev ua haujlwm kho mob zoo heev.
