Tshuab pom rensPuas yog lub lens tsim rau siv rau hauv tshuab lub zeem muag tshuab, tseem hu tau ua cov iav lo ntsiab muag. Lub zeem muag tshuab feem ntau muaj cov koob yees duab muaj kev lag luam, cov ntsiab muag, teeb tsa cov software, thiab cov duab ua software.
Lawv raug siv los sau, cov txheej txheem, thiab txheeb xyuas cov duab kom txiav txim siab qhov zoo ntawm kev ua haujlwm lossis ua tiav txoj hauj lwm ntsuas tsis muaj kev sib cuag. Lawv feem ntau yog siv rau kev ntsuas siab-pre-precision, kev sim tshuaj, tsis yog kev puas tsuaj, kev siv neeg hlau thiab ntau lwm cov teb.
1.Dab tsi yuav tsum tau koj xav txog thaum xaiv tshuab lub zeem muag zoo nkauj?
Thaum xaivTshuab Pom Cov Ntsia, koj yuav tsum xav txog ntau yam ntawm yam kom pom cov lens uas zoo tshaj plaws rau koj. Cov lus hauv qab no yog cov kev txiav txim siab zoo:
Teb ntawm pom (FOV) thiab ua haujlwm deb (WD).
Teb ntawm kev pom thiab kev ua haujlwm deb tau txiav txim siab ntau yam khoom uas koj tuaj yeem pom thiab qhov kev ncua deb ntawm lub lens mus rau qhov khoom.
Cov koob yees duab hom thiab sensor loj.
Lub lens koj xaiv yuav tsum phim koj lub koob yees duab interface, thiab cov duab curvature ntawm lub lens yuav tsum muaj ntau dua los yog sib npaug ntawm cov kab pheeb ces kaum kev deb ntawm lub sensor.
Kis cov nqaj hluav taws xob ci ci.
Nws yog ib qho tsim nyog los qhia meej seb koj daim ntawv thov yuav tsum muaj kev cuam tshuam tsawg, muaj kev daws teeb meem siab, loj lossis loj aperture lens configuration.
Khoom me me thiab daws teeb meem.
Yuav tsum tau cov khoom loj npaum li cas uas yuav tsum tau kuaj pom thiab qhov kev txiav txim siab zoo li cas, uas yog tus txiav txim siab qhov chaw twg thiab muaj pes tsawg pixels lub koob yees duab koj xav tau.
Environmental tej yam kev mob.
Yog tias koj muaj cov kev cai tshwj xeeb rau ib puag ncig, xws li kev qaug cawv, plua plav lossis dej tsis tau, koj yuav tsum tau xaiv lub lens uas tuaj yeem ua tau cov kev xav tau no.
Tus nqi nyiaj txiag.
Tus nqi twg koj tuaj yeem them taus cuam tshuam rau Lens hom thiab qauv koj tus kheej koj kawg xaiv.
Tshuab Lub Zeem Muag Lens
2.Txoj Qauv Ntawm Lub Cav Pom Lub Tshuab Ntshiab
Muaj ntau ntau yam los txiav txim siab thaum xaiv cov iav lo ntsiab muag.Tshuab Pom Cov NtsiaKuj tseem tuaj yeem muab faib ua ntau hom raws li cov qauv sib txawv:
Raws li hom kev ntsuas ntev, nws tuaj yeem faib ua:
Cov ntsiab lus tseem ceeb (Focal ntev yog tsau thiab tsis tuaj yeem hloov kho), rub lub lens (focal ntev yog kho tau thiab hloov tau).
Raws li lub aperture hom, nws tuaj yeem faib ua:
Phau ntawv Aperture Lens (lub aperture xav tau kho tus kheej), tsis siv neeg aperture lens (lub lens tuaj yeem hloov kho lub aperture raws li lub ambient lub teeb).
Raws li cov kev daws teeb meem kev daws teeb meem, nws tuaj yeem faib ua:
Cov qauv kev daws teeb meem (haum rau kev tshawb fawb dav dav thiab kev tshuaj xyuas kev ua haujlwm zoo dua qub (kev siv hluav taws xob zoo siab).
Raws li lub sensor loj, nws tuaj yeem faib ua:
Me me sensor hom iav lo ntsiab muag (haum rau cov sensors me me xws li 1/4 ", 1/3", 1/3 ", 1/3", 1/3 ", 1/3", 1 " , etc. sensor), loj sensor hom lo ntsiab muag (rau 35 hli puv-thav duab lossis loj sensors).
Raws li cov kev xav hom, nws tuaj yeem faib ua:
Monochrome Kev Ntsuas Lens (tsuas yog ntes cov xim dub thiab dawb), xim xim lens (tuaj yeem ntes cov duab xim).
Raws li cov cai tshwj xeeb yuav tsum tau ua, nws tuaj yeem faib ua:Tsawg-distortion lo ntsiab muag(Uas tuaj yeem txo qhov cuam tshuam ntawm distortion ntawm cov duab zoo thiab yog qhov tsim nyog rau cov ntawv qhia lo ntsiab lus uas yuav tsum tau ntsuas kev lag luam nrog cov kev lag luam loj), thiab lwm yam.
