Yiziphi izinzuzo zamalensi we-bi-telecentric? Umehluko phakathi kwelensi ye-bi-telecentric ne-telecentric

A lens ye-bi-telecentricIngabe ilensi eyenziwe ngezinto ezimbili zokubona ezinenkomba ehlukile ye-reuctive nezakhiwo zokuphrinta. Inhloso yayo eyinhloko ukunciphisa noma ukuqeda ama-affitions, ikakhulukazi ama-chromatic abrartion, ngokuhlanganisa izinto ezahlukene zokubona, ngaleyo ndlela athuthukise ikhwalithi yelensi.

1,Yini izinzuzo ze-bi-ama-telecentric lens?

Ama-lens we-bi-telecentric anezinzuzo eziningi ezivelele, kepha futhi zinzima kakhulu ukuzisebenzisa futhi zidinga amakhono amaningi okusebenzisa. Ake sibheke izinzuzo ze-Bi-Telecentric Lens ngokuningiliziwe:

1)Dala imiphumela ekhethekile yokubuka

Ama-lens we-bi-telecentric angadala imiphumela ebukwayo engeke itholwe ngamalensi ajwayelekile, njengokuguqula ukujula kwensimu nokwakha umphumela obizwa ngokuthi "umphumela we-miniature" umphumela.

2)Lawula umbono wesithombe

Ilensi ye-bi-telecentric ingalawula umbono wesithombe, lungisa ukuhlanekezela kwemiphetho yokwakha, futhi ugcine imigqa esetshenzisiwe iqonde ngaphandle kokugoba.

3)Yenza ukulawula kokugxila

Ama-lens we-bi-telecentric avumela ukulungiswa okuzimele kokugxile nokujula kwendiza, okungenzeki ngamalensi ajwayelekile ahleliwe.

4)Ikhwalithi enhle yesithombe

Ngenxa yokwakheka kwabo,ama-bi-telecentric lenszivame ukuba nokusebenza okuhle kakhulu kwekhwalithi yekhwalithi nekhwalithi yesithombe.

5)Ukuvumelana nezimo okusebenzayo

Yize ama-bi-telecent lens adinga ukusebenza ngesandla nokulawula, anikela ngezinga elithile lokuguquguquka okuvumela umthwebuli wezithombe ukuthi alawule isithombe ngokuya ngezidingo ezithile.

6)Cela imiphumela ehlukene

Ngokushintsha ukutshekiswa nokususwa kwamalensi, abathwebuli bezithombe bangadala imiphumela ehlukahlukene ehlukahlukene ngamalensi we-bi-telecentric.

2,Umehluko phakathi kwe-bi-I-telecentric lens kanye nelensi ye-telecentric

Umehluko omkhulu phakathi kwelensi ye-bi-telecentric ne-telecentric lens yikhono lokuguqula i-angle yelensi bese uhambisa ilensi:

1)Lens ye-bi-telecentric

Ama-lens we-bi-telecentric ngokuvamile abhekisela kuma-telecentric lens anamalensi amabili angalungiswa ngokwahlukana. Bangakwazi ukuhamba bakhuphuke futhi behle (suka) bese besobunxele nakwesokudla (sway), futhi bangashintsha futhi i-angle evuthayo.

Idizayini yelensi ye-bi-telecentric inika abathwebuli bezithombe ukulawula okukhulu nenkululeko yokudala, kepha ngasikhathi sinye kunzima kakhulu ukusebenza, edinga ubuchwepheshe obuphakeme kanye namasu amakhulu.

Selensi ephelele, ama-bi-telececc ama-lens anikela ngenkululeko enkulu yokulawula futhi adale izithombe ezidala futhi afake isikhalazo esihlala njalo, kodwa futhi eza nentengo ephakeme kanye nezidingo zobuchwepheshe ezinzima kakhulu ukukwazi.

2)Ama-telecentric lens

Ama-telecentric lensVumela abathwebuli bezithombe ukuthi balungise i-engela yelensi ukuze ilensi ne-sensor abasafani ngokufana, bavumele umthwebuli wezithombe ukuthi alawule ukujula kokugxila futhi adale imiphumela enamandla futhi edala.

Ngakolunye uhlangothi, i-lens yelensi ye-telecentric nayo ingahanjiswa noma "ukususwa," ukuguqula ukwakheka ngaphandle kokushintsha i-angle yekhamera, okuzuzisa ngokulawula nokulungisa umbono.

Imicabango yokugcina:

Uma unesifiso sokuthenga izinhlobo ezahlukahlukene zamalensi zokubhekwa, ukuskena, ama-drones, ekhaya elihlakaniphile, noma okunye ukusetshenziswa, sinakho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngama-lens ethu nezinye izesekeli.
