一, Lub sijhawm yog lub davhlau koob yees duab?

Lub sij hawm-ntawm-davhlau (TOF) cov koob yees duab yog hom kev xav tau ntawm lub koob yees duab thiab cov khoom uas ntsuas qhov kev ncua deb ntawm kev siv lub teeb rau cov khoom thiab rov qab rau lub koob yees duab. Lawv feem ntau siv nyob rau hauv ntau yam kev thov xws li Augmented Reality, Robotics, 3D scanning, yoj tes lees paub, thiab lwm yam.

TOF cov koob yees duabUa haujlwm los ntawm emitting teeb liab, feem ntau infrared lub teeb, thiab ntsuas lub sij hawm nws siv sij hawm rau lub teeb liab rov qab tom qab ntaus cov khoom hauv qhov xwm txheej. Lub sijhawm ntsuas lub sijhawm no tau siv los laij cov kev ncua deb rau cov khoom, tsim cov ncauj lus qhia tob lossis 3D sawv cev ntawm qhov chaw.

Lub sijhawm ntawm cov duab ya davhlau

Piv rau lwm qhov tob-hnov cov thev naus laus zis zoo li lub teeb pom kev lossis lub suab paj nruag lub zeem muag, TOF cov koob yees duab muaj ntau cov txiaj ntsig. Lawv muab cov ntaub ntawv tob tiag tiag, muaj kev tsim qauv yooj yim, thiab tuaj yeem ua haujlwm hauv ntau yam teeb pom kev zoo. TOF cov koob yees duab kuj yog kev cog lus thiab tuaj yeem sib xyaw rau hauv cov khoom siv me xws li smartphones, ntsiav tshuaj, thiab cov khoom siv hnav.

Cov ntawv thov ntawm koob yees duab nas cov koob yees duab muaj ntau haiv neeg. Hauv Augmented kev muaj tiag, TOF koob yees duab tuaj yeem ntes qhov tob ntawm cov khoom thiab txhim kho cov khoom muaj tseeb ntawm cov khoom ntawm lub ntiaj teb tiag. Hauv kev sib ntaus hlau, lawv pab kom cov neeg hlau kom pom tau lawv ib puag ncig thiab nrhiav kev sib tw tau zoo dua. Hauv 3D kos, TOF cov koob yees duab tuaj yeem ntes cov duab geometry ntawm cov khoom lossis ib puag ncig rau ntau lub hom phiaj zoo li Virtual kev muaj tiag, kev ua si, lossis luam tawm 3D. Lawv kuj siv nyob rau hauv cov ntawv thov biometric, xws li kev paub txog kev paub lossis kev taw tes tes piav tes.

,Cheebtsam ntawm lub sijhawm ntawm cov davhlau koob yees duab

Lub sij hawm-ntawm-davhlau (TOF) koob yees duabMuaj ntau cov ntsiab lus tseem ceeb uas ua haujlwm ua ke kom muaj kev pom tob thiab ntsuas kev deb. Cov feem ntau yuav txawv nyob ntawm tus qauv tsim thiab cov chaw tsim khoom, tab sis ntawm no yog cov ntsiab lus tseem ceeb uas ib txwm pom hauv cov koob yees duab TOOF

Qhov Chaw Teeb:

TOF cov koob yees duab siv lub teeb pom kev zoo rau kev tawm ntawm lub teeb liab, feem ntau nyob rau hauv daim ntawv ntawm infrared (ir) teeb. Lub hauv paus qhov teeb pom kev tuaj yeem yog tus coj (lub teeb-emitting diode) lossis ib liver diode, nyob ntawm lub koob yees duab tus qauv tsim. Lub teeb pom kev mus rau cov khoom hauv qhov chaw.

Optics:

Lub lens khaws lub teeb thiab cov duab nyob ib puag ncig rau cov duab sensor (focal dav hlau array). Kev siv kho qhov muag-dhau lim tsuas yog hla lub teeb nrog tib lub nthwv dej yog cov chaw nres nkoj. Qhov no pab tau kev xoo tsis muaj qhov thaiv thiab txo suab nrov.

Cov Duab Sensor:

Qhov no yog lub plawv ntawm koob yees duab TOF. Txhua tus pixel ntsuas lub sijhawm lub teeb tau coj mus ncig ntawm cov chaw nres nkoj (laser lossis coj) rau cov khoom thiab rov qab rau lub dav hlau lub dav hlau array.

Sij hawm circuitry:

Txhawm rau ntsuas lub sijhawm-ntawm-davhlau yog, lub koob yees duab xav tau kev xav tau sijhawm sijhawm. Txoj kev tswj hwm hluav taws xob no tau tswj hwm ntawm lub teeb liab thiab kuaj pom lub sijhawm nws yuav siv rau lub teeb pom kev mus rau cov khoom thiab rov qab mus rau lub koob yees duab. Nws synchronizes lub koob tso tawm thiab kev pom cov txheej txheem kom ntseeg tau tias kev ntsuas kev deb.

Hloov:

Ib coTOF cov koob yees duabTeeb tsa cov txheej txheem kev txhim kho los txhim kho qhov raug thiab muaj kev ntsuas ntawm kev deb. Cov koob yees duab no hloov lub teeb pom kev zoo nrog cov qauv tshwj xeeb lossis ntau zaus. Cov kev sib cais pab kom pom qhov txawv ntawm lub teeb emitted los ntawm lwm qhov chaw puag ncig thiab txhim kho lub koob yees duab muaj peev xwm sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv.

Qhov tob muab cais algorithm:

Txhawm rau hloov lub sijhawm-ntawm-davhlau kev ntsuas mus rau hauv cov ntaub ntawv tob, TOF cov koob yees duab tau siv cov txheej txheem sib txawv. Cov algorithms tshawb xyuas cov ntaub ntawv ncua sij hawm tau txais los ntawm cov photodetector thiab xam qhov kev ncua deb ntawm lub koob yees duab thiab cov khoom hauv qhov xwm txheej. Lub qhov tob muab rho tawm cov txheej txheem feem ntau koom nrog kev them nyiaj rau qhov hluav taws xob sib txawv, thiab muaj kev cuam tshuam loj.

Cov ntaub ntawv tob tau tsim tawm:

Thaum qhov kev xam tob tob tau ua, lub koob yees duab koob phij cuam muab cov ntaub ntawv tso zis ntau dua. Cov zis no tuaj yeem siv daim ntawv ntawm daim duab qhia tob, muaj huab ntxoo, lossis 3D sawv cev ntawm qhov chaw. Cov ntaub ntawv tob tuaj yeem siv tau los ntawm kev thov thiab tshuab kom pab tau ntau yam ua haujlwm zoo li khoom taug qab, augmented kev muaj tiag, lossis cov kev muaj tiag.

Nws yog ib qho tseem ceeb kom nco ntsoov tias kev siv tshwj xeeb ntawm cov koob yees duab TOF tuaj yeem sib txawv thoob plaws cov chaw tsim khoom thiab cov qauv. Kev nce qib hauv cov thev naus laus zis yuav qhia cov nta ntxiv thiab kev txhim kho txhawm rau txhim kho kev ua tau zoo thiab lub peev xwm ntawm cov koob yees duab TOF.
