Ilensi yocingo luhlobo lweilensi yokubona, ekwabizwa ngokuba yi-lens kamabonakude, okanye ilensi ye-telephoto.Ngoyilo olukhethekileyo lwelensi, ubude bayo bokujongwa bubude, kwaye ubude bomzimba belensi budla ngokuba buncinci kunobude obugxininisiweyo.Uphawu kukuba inokubonisa izinto ezikude ezinkulu kunobukhulu bazo bokwenyani, ngoko inokubamba imbonakalo ekude okanye izinto ngokucacileyo nangenkcukacha.

Iilensi zeTelecentric zisetyenziswa kakhulu kwimiboniso efana nemidlalo, izilwanyana zasendle kunye nokufota kwendalo, kunye nokuphononongwa kweenkwenkwezi, kuba le miboniso ihlala ifuna ukudubula okanye ukujonga izinto ezikude.Iilensi zeTelecentricinokuzisa izinto ezikude "kufutshane" ngelixa igcina ukucaca kunye neenkcukacha zomfanekiso.

Ukongeza, ngenxa yobude obude bokujongwa kweelensi zetelecentric, banokufikelela kwimfiliba yangasemva kunye nobunzulu bebala, nto leyo eyenza umxholo ubonakale ngakumbi xa kufotwa, ngoko ke zikwasetyenziswa ngokubanzi kumfanekiso wokufota.

Ilensi yocingo

1.Iimpawu eziphambili zeelensi zocingo

Umgaqo osebenzayo welensi ye-telecentric kukusebenzisa isakhiwo sayo esikhethekileyo ukusabalalisa ukukhanya ngokulinganayo kunye neprojekthi yomfanekiso kwi-sensor okanye ifilimu.Olu phawu luyivumela ukuba ifezekise iziphumo ezingcono zemifanekiso xa ifota izigcawu kude nesihloko.Ke, zithini iimpawu zeelensi zocingo?

Umfanekiso ochanekileyo kakhulu:

Umfanekiso womda weilensi yocingoayiyi kugoba.Nangona kumda we-lens, imigca isagcina i-angle ye-intersection efanayo kunye ne-axis ephakathi ye-lens, ngoko imifanekiso echanekileyo inokuthatyathwa.

Ingqiqo eyomeleleyo ye-dimensional-dimensional:

Ngenxa yeprojekti ye-orthogonal, i-lens ye-telecentric inokugcina ubudlelwane obulinganayo bendawo, ukwenza imifanekiso ethathiweyo ibe nengqiqo eyomeleleyo ye-three-dimensional.

Imigca enxuseneyo:

Ngenxa yesakhiwo esikhethekileyo sangaphakathi se-optical, i-telecentric lens inokugcina ukukhanya kungena kwi-lens parallel kuzo zonke izikhundla, oku kuthetha ukuba imigca yemifanekiso ebanjwe yi-lens iya kuhlala ithe tye ngaphandle kokugoba okanye ukuguqulwa.

2.Usetyenziso oluphambili lweelensi zocingo

Iilensi zeTelecentric zisetyenziswa ngokubanzi kule mimandla ilandelayo:

Usetyenziso lwemifanekiso

Kwimimandla efana nombono wekhompyutheni efuna ukulungiswa komfanekiso, iilensi ze-telecentric zisetyenziswa ngokubanzi ngenxa yeziphumo zazo ezichanekileyo eziphezulu, ezenza ukusetyenzwa komfanekiso kuchaneke ngakumbi.

Izicelo zovavanyo lweshishini

Iilensi zeTelecentric zihlala zisetyenziswa kuhlolo oluthile lwemizi-mveliso olufuna umfanekiso ochanekileyo.

Isicelo sobuchwephesha bokufotas

Kwiifoto ezithile zobuchwephesha,iilensi zocingozihlala zisetyenziswa, njengokufota kwezakhiwo, iifoto zemveliso, njl.

Ukufota ngenqwelomoya kunye nezicelo zokufota ngefowuni

Kufoti wenqwelomoya kunye nokufota ngefowuni, iilensi zetelecentric zinokuthatha imifanekiso enobukhulu obuthathu obunamandla kunye nokuchaneka okuphezulu, kwaye zisetyenziswa ngokubanzi.
