Tshuab pom lensyog lub lens tsim los siv rau hauv tshuab pom kev, tseem hu ua lub koob yees duab lub koob yees duab.Lub tshuab pom lub tshuab feem ntau muaj cov koob yees duab, cov lo ntsiab muag, lub teeb pom kev zoo, thiab cov duab ua software.

Lawv raug siv los khaws cia, txheej txheem, thiab tshuaj xyuas cov duab kom txiav txim siab qhov zoo ntawm cov khoom ua haujlwm lossis ua tiav qhov kev ntsuas qhov tseeb yam tsis muaj kev sib cuag.Lawv feem ntau siv rau kev ntsuas kev ntsuas siab, kev sib dhos tsis siv neeg, kev sim tsis muaj kev puas tsuaj, kuaj pom qhov tsis xws luag, neeg hlau navigation thiab ntau lwm yam.

1.Koj yuav tsum xav txog dab tsi thaum xaiv lub tshuab tsis pom kev lo ntsiab muag?

Thaum xaivtshuab visions, koj yuav tsum xav txog ntau yam los nrhiav lub lens uas haum rau koj.Cov hauv qab no yog cov kev txiav txim siab ntau:

Field of View (FOV) thiab ua haujlwm nrug (WD).

Kev pom thiab kev ua haujlwm nyob deb txiav txim siab npaum li cas cov khoom koj tuaj yeem pom thiab qhov deb ntawm lub lens mus rau qhov khoom.

Tau tshaj lub 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 siab dua los yog sib npaug ntawm kab pheeb ces kaum ntawm lub sensor.

Transmitted beam xwm txheej beam.

Nws yog ib qho tsim nyog kom paub meej seb koj daim ntawv thov yuav tsum muaj kev cuam tshuam tsawg, kev daws teeb meem siab, qhov tob loj lossis loj aperture lens configuration.

Yam khoom loj thiab muaj peev xwm daws teeb meem.

Qhov loj npaum li cas cov khoom koj xav ntes thiab qhov kev daws teeb meem zoo npaum li cas yuav tsum tau ua kom pom tseeb, uas txiav txim siab seb qhov loj npaum li cas thiab 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 shockproof, dustproof lossis waterproof, koj yuav tsum xaiv lub lens uas tuaj yeem ua tau raws li cov cai no.

Tus nqi siv nyiaj.

Tus nqi dab tsi koj tuaj yeem them tau yuav cuam tshuam rau lub lens hom thiab qauv koj xaiv thaum kawg.

Lub tshuab pom lub lens

2.Classification method of machine vision lenses

Muaj ntau yam yuav tsum xav txog thaum xaiv lo ntsiab muag.Tshuab pom qhov muag lo ntsiab muagkuj tseem tuaj yeem muab faib ua ntau hom raws li cov qauv sib txawv:

Raws li hom focal ntev, nws tuaj yeem muab faib ua: 

Tsau tsom iav lens (focal ntev yog tsau thiab tsis tuaj yeem hloov kho), zoom lens (focal ntev adjustable thiab ua haujlwm yog hloov tau).

Raws li hom aperture, nws tuaj yeem muab faib ua: 

Phau ntawv aperture lo ntsiab muag (lub aperture yuav tsum tau kho manually), tsis siv neeg aperture lens (lub lens tuaj yeem kho qhov aperture raws li lub teeb pom kev zoo).

Raws li cov kev xav tau kev daws teeb meem, nws tuaj yeem muab faib ua: 

Cov txheej txheem daws teeb meem lo ntsiab muag (tsim rau cov kev xav tau dav dav xws li kev soj ntsuam zoo tib yam thiab kev soj ntsuam zoo), cov lo ntsiab muag siab (tsim rau kev kuaj pom tseeb, kev ntsuas nrawm thiab lwm yam kev siv nrog cov kev xav tau siab dua).

Raws li qhov loj ntawm lub sensor, nws tuaj yeem muab faib ua: 

Me me sensor hom lo ntsiab muag (tsim rau me me sensors xws li 1/4 ", 1/3", 1/2 ", thiab lwm yam), nruab nrab sensor hom lo ntsiab muag (tsim rau nruab nrab sensors xws li 2/3", 1 " , thiab lwm yam. sensor), loj sensor hom lo ntsiab muag (rau 35mm full-frame lossis loj sensors).

Raws li hom duab, nws tuaj yeem muab faib ua: 

Monochrome imaging lens (tuaj yeem ntes cov duab dub thiab dawb), xim duab lens (tuaj yeem ntes cov duab xim).

Raws li kev ua haujlwm tshwj xeeb, nws tuaj yeem muab faib ua:low-distortion lo ntsiab muag(uas tuaj yeem txo qhov cuam tshuam ntawm kev cuam tshuam ntawm cov duab zoo thiab tsim nyog rau daim ntawv thov scenarios uas yuav tsum tau ntsuas qhov tseeb), tiv thaiv kev vibration lo ntsiab muag (tsim rau kev lag luam ib puag ncig nrog kev co loj), thiab lwm yam.
