Njengengxenye esemqoka yohlelo lokubona komshini, amakhamera wezimboni avame ukufakwa emgqeni womhlangano womshini ukuze athathe iso lomuntu lokulinganisa nokwahlulela. Ngakho-ke, ukukhetha ilensi yekhamera efanelekile futhi kuyingxenye ebaluleke kakhulu yokwakheka kohlelo lomshini.
Ngakho-ke, kufanele sikhethe kanjani okufaneleIlensi yekhamera yezimboni? Yiziphi izingqinamba okufanele zibhekwe lapho ukhetha ilensi yekhamera yezimboni? Ake sibheke ndawonye.
1.Ukucatshangelwa okuyisisekelo kokukhetha ama-lens wekhamera yezimboni
①Khetha ikhamera ye-CCD noma ye-CCOS ngokuya ngezicelo ezahlukahlukene
Ama-lens wekhamera ekhakhakha yezimboni asetshenziselwa ikakhulukazi ukukhishwa kwesithombe kwezinto ezihambayo. Vele, ngokuthuthukiswa kobuchwepheshe be-CMOS, amakhamera we-CMOs Industrial asetshenziswa nemishini eminingi yokubekwa kwe-chip. Amakhamera we-CCD wezimboni asetshenziswa kabanzi emkhakheni wokuhlola okuzenzakalelayo okubonakalayo. Amakhamera we-CMOS Industrial asetshenziswa kabanzi ngenxa yezindleko zawo eziphansi kanye nokusetshenziswa kwamandla okuphansi.
Amakhamera wezimboni asetshenziswa emigqeni yokukhiqiza
②Ukulungiswa kwamalensi wekhamera yezimboni
Okokuqala, isinqumo sikhethwa ngokubheka ukunemba kwento ebonwa noma kukalwa. Uma ukunemba kwe-pixel yekhamera = Inkambu yokuqondisa eyodwa yosayizi wokubuka / ukulungiswa kwekhamera yokuqondisa okukodwa, bese kulungiswa ukulungiswa kwekhamera yekhamera = Inkambu yokuqondisa eyodwa yosayizi / ukunemba okukodwa.
Uma inkambu eyodwa yokubuka ingu-5mm futhi ukunemba kwethiyori kungu-0.02mm, ukulungiswa okuqondile okukodwa kungu-5 / 0.02 = 250. Kodwa-ke, ukuze wandise ukuqina kohlelo, akunakwenzeka ukuhambelana nenani lokulinganisa / ukunemba kokunemba ngeyunithi elilodwa le-pixel. Ngokuvamile, angaphezu kwe-4 angakhethwa, ngakho-ke ikhamera idinga ukuqondiswa okuqondile okukodwa kwama-1000 namaphikseli ayizigidi eziyi-1,3.
Okwesibili, ukucubungula umphumela wamakhamera wezimboni, ukulungiswa okuphezulu kuyasiza ekubukeni kokuma noma ukuhlaziywa kanye nokwamukelwa kwesoftware yomshini. Uma kungukukhishwa kwe-VGA noma kwe-USB, kufanele kubhekwe kumqaphi, ngakho-ke ukulungiswa komqaphi kufanele kubhekwe. Akunandaba ukuthi kuphakama kangakanani ukulungiswa kobuchwepheshe bezobubonazi bezimboniAma-lens wekhamera embonini, ngeke kube nomqondo obuningi uma ukulungiswa komqaphi akwanele. Ukulungiswa okuphezulu kwamakhamera wezimboni kuyasiza futhi uma usebenzisa amakhadi wememori noma ukuthatha izithombe.
③Uhlaka lwekhameraintelayelensi yekhamera yezimboni
Lapho into ilinganiswa ihamba, ilensi yekhamera yezimboni enezilinganiso eziphakeme zozimele kufanele zikhethwe. Kepha ngokuvamile ekhuluma, kukhuphuka isisombululo esiphakeme, iphansi isilinganiso sohlaka.
④Ukumadanisa ama-lens wezimboni
Usayizi we-chip we-sensor kufanele abe mancane kune noma alingane nosayizi welensi, futhi i-C noma i-CS Mount kufanele futhi ihambisane.

①C-Mount noma i-CS-Mount
Ibanga elibonakalayo le-C-Mount lingu-17.5mm, kanye nebanga elibonakalayo le-CS-Mount li-12,5mm. Ungagxila kuphela lapho ukhetha isikhombimsebenzisi esifanele.
Umehluko phakathi kwezindawo ezahlukahlukene
②Usayizi wedivayisi yezithombe
Ye-chip 2/3-intshi photossen chip, kufanele ukhethe iIlensi yekhamera yezimboniokuhambelana nekhoyili yokucabanga. Uma ukhetha u-1/3 noma 1/2 intshi, kuzovela ekhoneni elikhudlwana elimnyama.
③Khetha ubude obugxile
Okusho ukuthi, khetha ilensi yezimboni enenkambu yokubuka ikhudlwana kunebanga lokubona.
④Ukujula kwenkambu kanye nemvelo yokukhanyisa kufanele kuhambisane
Ezindaweni ezinokukhanya okwanele noma ukunqwala okuphezulu okuphezulu, ungakhetha ukuthambekela okuncane ukwandisa ukujula kwensimu futhi ngaleyo ndlela kuthuthukise ukucaciseleka kokudubula; Ezindaweni ezinokukhanya okunganele, ungakhetha i-aperture enkulu kancane, noma ukhethe i-chip evelele ngokuzwela okuphezulu.
Ngaphezu kwalokho, ukuze ukhethe ilensi yekhamera yelungelo elifanele, futhi udinga ukunaka izitayela ezithandwayo. Isibonelo, izinzwa zezithombe zenze intuthuko enkulu eminyakeni yamuva nje, kanye nomkhuba oya kumaphikiseli amaningi nangokuthe xaxa ukwenza ngcono ukulungiswa kweAma-lens wekhamera embonini, kanye nokuzwela okuphezulu (izinzwa zezithombe zangemuva). Ngaphezu kwalokho, ubuchwepheshe be-CCD buye basebenza kahle futhi manje babelana ngemisebenzi eminingi neminye imisebenzi ye-CMOS Technology Sensors.
Imicabango yokugcina:
UChuangan wenza ukwakheka kokuqala nokukhiqizwa kwamalensi wekhamera yezimboni, asetshenziswa kuzo zonke izici zezicelo zezimboni. Uma unentshisekelo noma unezidingo zamalensi wekhamera yezimboni, sicela uxhumane nathi ngokushesha okukhulu.
