Lub lens pom kev ntawm lub tshuab yog dab tsi?
A lub lens pom kev ntawm lub tshuabyog ib qho tseem ceeb hauv lub tshuab pom kev, uas feem ntau siv rau hauv kev tsim khoom, robotics, thiab kev tshuaj xyuas kev lag luam. Lub lens pab ntes cov duab, txhais cov nthwv dej teeb rau hauv hom ntawv digital uas lub system tuaj yeem nkag siab thiab ua tiav. Qhov zoo thiab cov yam ntxwv ntawm lub lens tuaj yeem cuam tshuam loj heev rau lub system lub peev xwm los txheeb xyuas, ntsuas, lossis tshuaj xyuas cov khoom.
Cov no yog dab tsi hom lens pom kev ntawm lub tshuab?
Qee hom lens pom kev ntawm lub tshuab muaj xws li:
1. Cov iav tsom iav uas ntev focal: Cov tsom iav no muaj qhov ntev focal ruaj khov thiab muab qhov magnification tas li rau kev thaij duab ntawm cov khoom ntawm qhov deb tshwj xeeb ntawm lub lens. Lawv tsim nyog rau cov ntawv thov uas qhov deb ua haujlwm thiab qhov loj ntawm cov khoom tseem ruaj khov.
2. Cov iav zoom:Cov tsom iav zoom muaj qhov ntev focal uas hloov tau, ua rau cov neeg siv hloov qhov pom thiab qhov loj raws li qhov xav tau. Lawv muab kev ywj pheej hauv kev thaij duab ntawm cov khoom ntawm ntau qhov deb sib txawv.
3. Cov iav tsom iav Telecentric:Cov iav tsom iav Telecentric yog tsim los tsim cov teeb ci sib luag, uas txhais tau tias cov teeb ci tseem ceeb yog perpendicular rau lub sensor duab. Qhov cwj pwm no ua rau muaj kev ntsuas qhov loj ntawm cov khoom kom raug thiab sib xws, ua rau lawv haum rau kev ntsuas qhov tseeb.
4.Cov iav dav dav: Cov iav tsom iav dav dav muaj qhov ntev focal luv thiab qhov pom dav, ua rau lawv muaj txiaj ntsig zoo rau cov ntawv thov uas xav tau kev thaij duab ntawm thaj chaw loj lossis cov xwm txheej.
Thaum xaiv lub lens pom kev ntawm lub tshuab, cov yam uas yuav tsum xav txog suav nrog qhov deb ua haujlwm xav tau, thaj chaw pom, kev daws teeb meem, qhov zoo ntawm daim duab, kev sib xws ntawm lub lens, thiab cov kev cai tshwj xeeb ntawm daim ntawv thov.
Cov yam ntxwv ntawm lub tshuab pom kev lens yog dab tsi?s?
Cov yam ntxwv ntawm cov iav tsom iav pom kev ntawm lub tshuab yuav txawv nyob ntawm tus neeg tsim khoom thiab tus qauv iav tshwj xeeb. Txawm li cas los xij, qee qhov yam ntxwv ntawm cov iav tsom iav pom kev ntawm lub tshuab suav nrog:
1. Cov khoom siv kho qhov muag siab:Cov iav tsom pom kev ntawm lub tshuab yog tsim los muab cov duab meej thiab ntse, feem ntau phim cov peev xwm daws teeb meem ntawm cov koob yees duab siab.
2. Kev cuam tshuam tsawg: Cov iav uas muaj qhov tsis sib xws tsawg ua kom cov duab thaij tau raug thiab tsis muaj qhov tsis sib xws, tshwj xeeb tshaj yog rau cov ntawv thov uas xav tau kev ntsuas lossis kev tshuaj xyuas kom meej.
3. Ntau yam spectral dav dav:Qee lub iav pom kev ntawm lub tshuab yog tsim los ua haujlwm nrog ntau lub teeb sib txawv, uas tso cai rau cov ntawv thov uas siv lub teeb pom kev, lub teeb ultraviolet (UV), lub teeb infrared (IR), lossis ntau lub teeb duab.
4. Kev hloov pauv thiab kev ywj pheej: Qee cov iav tsom iav, xws li cov iav tsom iav zoom, muaj qhov ntev ntawm qhov muag thiab qhov pom kev hloov kho tau, muab lub peev xwm los thaij duab ntawm ntau yam kev loj hlob thiab qhov deb ntawm cov khoom.
5. Kev sib txuas lus: Cov iav tsom iav telecentric tsim cov teeb sib luag, ua rau muaj qhov loj me sib xws thiab ntsuas qhov loj ntawm cov khoom kom raug, tsis hais qhov deb ntawm cov khoom.
6. Kev kho kom pom tseeb: Cov iav tsom pom kev ntawm lub tshuab feem ntau muab kev kho qhov muag ntawm tes lossis siv lub cev muaj zog, uas ua rau cov neeg siv kho qhov muag kom zoo dua rau qhov sib txawv ntawm cov khoom.
7. Kev tsim qauv me me thiab sib dua: Cov iav tsom iav pom kev ntawm lub tshuab feem ntau yog tsim los kom me me thiab tsis hnyav, ua rau lawv haum rau kev koom ua ke rau hauv cov kab ke pom kev thiab txo qhov loj me.
8. Kev sib haum xeeb ntawm Mount: Cov iav tsom iav pom kev ntawm lub tshuab muaj ntau yam iav mounts (xws li C-mount, F-mount, M42, thiab lwm yam), ua kom ntseeg tau tias muaj kev sib raug zoo nrog ntau lub koob yees duab lossis cov interfaces.
9. Kev ruaj khov ib puag ncig: Qee lub iav tsom iav pom kev tau tsim los kom tiv taus cov chaw ua haujlwm hnyav, nrog rau cov yam ntxwv xws li lub tsev ruaj khov, tiv taus plua plav, thiab tiv taus kev co lossis kev hloov pauv ntawm qhov kub thiab txias.
10. Kev siv nyiaj tsim nyog: Cov tsom iav pom kev ntawm lub tshuab feem ntau tsom mus rau kev muab cov kev daws teeb meem uas pheej yig rau cov ntawv thov thaij duab, ua kom muaj kev sib npaug ntawm kev ua tau zoo thiab kev pheej yig.
Nws yog ib qho tseem ceeb uas yuav tsum soj ntsuam cov kev xav tau tshwj xeeb ntawm koj daim ntawv thov pom kev ntawm lub tshuab thiab xaiv cov yam ntxwv ntawm lub lens uas zoo tshaj plaws rau koj cov kev xav tau.
