Asebenza Kanjani Amalensi Eskena Solayini? Yimaphi Amapharamitha Okufanele Ngiwanake?

A umugqa wokuskena ilensiiyilensi ekhethekile esetshenziswa kakhulu kumakhamera wokuskena umugqa. Yenza ukuthwebula izithombe ngesivinini esiphezulu endaweni ethile. Ihlukile kumalensi ekhamera endabuko futhi imvamisa isetshenziswa emkhakheni wezimboni.

Uyini umgomo wokusebenza wokuskena komugqailensi?

Umgomo wokusebenza welensi yokuskena umugqa usekelwe ikakhulukazi kubuchwepheshe bokuskena komugqa. Lapho isebenza, ilensi yokuskena komugqa iskena isampula yendawo yomugqa ngomugqa futhi iqoqe ulwazi olukhanyayo lwerowu ngayinye yamaphikseli ukuze isize ilensi yokuskena komugqa ithwebule isithombe sayo yonke isampula esikhundleni sokuthwebula sonke isithombe ngesikhathi esisodwa.

Ngokuqondile, umgomo wokusebenza welensi yokuskena umugqa unezinyathelo ezimbalwa:

Isithombe se-Optical:Isignali yokukhanya yesampula ezoskenwa ithwetshulwa yizici zezithombe ezizwela umugqa ngomugqa kulensi yokuskena yomugqa bese iguqulelwa kumasiginali kagesi.

Ukuskena komugqa ngomugqa:Isici se-photosensitive somugqa ngomugqa siskena ukusuka phezulu siye phansi kwesampula ngesivinini esithile, siguqule ulwazi olukhanyayo lomugqa ngamunye lube isignali kagesi.

Ukucutshungulwa kwesignali:Ngemva kokucubungula, isignali kagesi iguqulwa ibe isignali yedijithali yokukhiqiza isithombe.

Ukuthungwa kwesithombe:hlanganisa ndawonye amasignali edijithali omugqa ngamunye ukuze ekugcineni wakhe isithombe salo lonke isampula.

Yimaphi amapharamitha okufanele anakwe kumalensi wokuskena komugqa?

Imingcele yeamalensi wokuskena umugqazihlobene eduze nezidingo ezahlukene kanye nezimo zohlelo lokusebenza. Amapharamitha alandelayo kumele agxiliswe kuwo:

Isixazululo

Ukulungiswa kwelensi yokuskena komugqa ngokuvamile kuyimethrikhi eyinhloko yokukhathazeka. Ukuphakama kokulungiswa, kuyanda ukucaca kwesithombe, okuhlobene nenani lamaphikseli endaweni yokuthwebula kanye nosayizi wesici sokuthwebula.

Imbobo

Usayizi wembobo ulawula inani lokukhanya elingena kulensi, okuthinta ukugqama kwesithombe selensi kanye nesikhathi sokuchayeka sefilimu. Imbobo enkulu ingathuthukisa ikhwalithi yesithombe uma isetshenziswa ezimeni zokukhanya okuphansi, kodwa ingase yehlise ububanzi bokujula.

Ibanga lokugxila

Ibanga lokugxila libhekisela ebangeni lebanga elingadutshulwa ilensi. Ngokuvamile, ububanzi bungcono, futhi bubanzi busho ukuthi ingadubula izinto eziningi ezinobude obuhlukile bokugxila.

Ubude besithombe

Ubude besithombe busho ubude bendawo yokuthwebula ilensi ekuqondeni kokuskena. Ubude besithombe esikhudlwana budinga isivinini sokuskena esisheshayo, esizophinda sibangele isivinini sokuthwebula isithombe esiphezulu kanye nezinga eliphezulu lokudluliswa kwedatha.

Iikhwalithi yokulinganisa

Ikhwalithi yokuthwebula ingalinganiswa ngamapharamitha afana nokulungiswa kwezinhlangothi, isilinganiso sesignali-kuya-nomsindo, nokugcwaliswa kwesikhala kombala. Ngokuvamile, ukulungiswa okuphezulu kwe-lateral, isilinganiso sesignali-kuya-nomsindo, nokugcwala kombala kusho ikhwalithi yesithombe ephezulu.

Usayizi welensi nesisindo

Usayizi nesisindo kungase kuthinte ukusetshenziswaamalensi wokuskena umugqakwezinye izinhlelo zokusebenza. Ngakho-ke, ubukhulu nesisindo se-lens nazo zidinga ukucatshangelwa ngokuvumelana nezimo ezihlukahlukene zohlelo lokusebenza.

Imicabango yokugcina:

Uma unentshisekelo yokuthenga izinhlobo ezahlukene zamalensi ukuze ugadwe, ukuskena, ama-drones, ikhaya elihlakaniphile, nanoma yikuphi okunye ukusetshenziswa, sinakho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi mayelana namalensi ethu nezinye izesekeli.
