Cov koob yees duab hauv tsheb siv dav hauvtshebteb, thiab lawv cov xwm txheej ntawm daim ntawv thov tau dhau los ua ntau haiv neeg, los ntawm cov ntaub ntawv tsav tsheb thaum ntxov tshaj plaws thiab cov duab thim rov qab mus rau kev paub txog kev txawj ntse, ADAS pab tsav tsheb, thiab lwm yam. Yog li ntawd, cov koob yees duab tsheb kuj tseem hu ua "lub qhov muag ntawm kev tsav tsheb tsis muaj neeg tsav" thiab tau dhau los ua cov khoom siv tseem ceeb hauv kev tsav tsheb tsis muaj neeg tsav.
1.Lub koob yees duab hauv tsheb yog dab tsi?
Lub koob yees duab hauv tsheb yog ib lub cuab yeej ua tiav uas muaj ntau yam khoom siv. Cov khoom siv kho vajtse tseem ceeb suav nrog cov iav tsom iav, cov cuab yeej ntsuas duab, cov khoom siv serializer, cov txheej txheem ua haujlwm teeb liab ISP, cov khoom sib txuas, thiab lwm yam.
Cov tsom iav kho qhov muag feem ntau yog lub luag haujlwm rau kev tsom lub teeb thiab tso tawm cov khoom hauv thaj chaw pom rau ntawm qhov chaw ntawm cov duab thaij duab. Nyob ntawm qhov yuav tsum tau ua rau cov teebmeem duab thaij duab, qhov yuav tsum tau ua rau cov khoom sib xyaw ua ke ntawm lub lens ntawmcov iav tsom iavkuj txawv.
Ib qho ntawm cov khoom ntawm lub koob yees duab tsheb: lub lens kho qhov muag
Cov cuab yeej siv duab siv tau lub zog hloov pauv photoelectric ntawm cov khoom siv photoelectric los hloov cov duab teeb ntawm qhov chaw photosensitive mus rau hauv lub teeb liab hluav taws xob uas sib npaug rau cov duab teeb. Lawv feem ntau muab faib ua CCD thiab CMOS.
Lub tshuab ua haujlwm teeb liab (ISP) tau txais cov ntaub ntawv raw ntawm liab, ntsuab thiab xiav los ntawm lub sensor, thiab ua ntau yam txheej txheem kho xws li tshem tawm cov teebmeem mosaic, kho xim, tshem tawm kev cuam tshuam ntawm lub lens, thiab ua kom cov ntaub ntawv compression zoo. Nws kuj tseem tuaj yeem ua tiav kev hloov pauv hom video, kev ntsuas duab, kev siv lub teeb tsis siv neeg, kev tsom mus rau qhov tseeb thiab lwm yam haujlwm.
Tus serializer tuaj yeem xa cov ntaub ntawv duab uas tau ua tiav lawm thiab siv tau los xa ntau hom ntaub ntawv duab xws li RGB, YUV, thiab lwm yam. Lub connector feem ntau yog siv los txuas thiab kho lub koob yees duab.
2.Cov txheej txheem xav tau rau cov koob yees duab hauv tsheb yog dab tsi?
Vim tias cov tsheb yuav tsum ua haujlwm nyob rau hauv ib puag ncig sab nraud ntev heev thiab yuav tsum tau tiv taus qhov kev sim ntawm ib puag ncig hnyav, cov koob yees duab tsheb yuav tsum muaj peev xwm ua haujlwm ruaj khov hauv ib puag ncig nyuaj xws li qhov kub thiab txias siab thiab qis, kev co muaj zog, av noo siab thiab cua sov. Yog li ntawd, cov kev cai rau cov koob yees duab tsheb hais txog cov txheej txheem tsim khoom thiab kev ntseeg siab yog siab dua li cov rau cov koob yees duab kev lag luam thiab cov koob yees duab kev lag luam.
Lub koob yees duab hauv tsheb
Feem ntau hais lus, cov txheej txheem xav tau rau lub koob yees duab tsheb feem ntau suav nrog cov hauv qab no:
①Kev kub siab tsis kam
Lub koob yees duab hauv tsheb yuav tsum ua haujlwm tau zoo li qub hauv qhov kub ntawm -40 ℃ ~ 85 ℃ thiab tuaj yeem hloov kho rau qhov kub thiab txias hloov pauv loj heev.
②Tiv taus dej
Qhov kev sib khi ntawm lub koob yees duab hauv tsheb yuav tsum nruj heev thiab nws yuav tsum siv tau ib txwm tom qab ntub dej nag ob peb hnub.
③Tiv taus av qeeg
Thaum lub tsheb tsav tsheb ntawm txoj kev tsis sib luag, nws yuav tsim cov kev co muaj zog, yog li ntawdlub koob yees duab tshebyuav tsum muaj peev xwm tiv taus kev co ntawm ntau yam zog.
Lub koob yees duab tsheb tiv thaiv kev co
④Antimagnetic
Thaum lub tsheb pib, nws yuav tsim cov hluav taws xob electromagnetic siab heev, uas yuav tsum tau lub koob yees duab hauv lub tsheb kom muaj kev ua haujlwm tiv thaiv magnetic siab heev.
⑤Suab nrov qis
Lub koob yees duab yuav tsum tau kom txo tau suab nrov thaum lub teeb tsaus ntuj, tshwj xeeb tshaj yog cov koob yees duab saib sab thiab saib tom qab yuav tsum tau thaij duab kom meej txawm tias thaum hmo ntuj.
⑥Kev ua haujlwm siab
Lub tsheb mus nrawm heev thiab qhov chaw kaj uas lub koob yees duab ntsib hloov pauv ntau heev thiab nquag, uas yuav tsum tau kom lub koob yees duab CMOS muaj cov yam ntxwv hloov pauv tau zoo heev.
⑦Lub kaum sab xis dav heev
Yuav tsum tau lub koob yees duab saib ib puag ncig ntawm sab yuav tsum yog lub kaum sab xis dav heev nrog lub kaum sab xis saib kab rov tav ntau dua 135°.
⑧Lub neej ua haujlwm
Lub neej ua haujlwm ntawm ib qholub koob yees duab tshebyuav tsum muaj tsawg kawg yog 8 txog 10 xyoo kom ua tau raws li qhov yuav tsum tau ua.
