Njengenxalenye ephambili yenkqubo yokubona umatshini, iikhamera zemizi-mveliso zihlala zifakelwa kumgca wokudibanisa umatshini ukuze zithathe indawo yeliso lomntu ukuze zilinganiswe kwaye zigwetywe. Ke ngoko, ukukhetha ilensi yekhamera efanelekileyo kukwayinxalenye ebalulekileyo yoyilo lwenkqubo yokubona umatshini.
Ngoko ke, sifanele sikhethe njani isithuthi esifanelekileyoilensi yekhamera yemizi-mvelisoZeziphi izinto ekufuneka ziqwalaselwe xa ukhetha ilensi yekhamera yemizi-mveliso? Makhe sijonge kunye.
1.Izinto ezisisiseko ekufuneka uziqwalasele xa ukhetha iilensi zekhamera zoshishino
①Khetha ikhamera ye-CCD okanye ye-CMOS ngokwezicelo ezahlukeneyo
Iilensi zekhamera zemizi-mveliso zeCCD zisetyenziswa kakhulu ekutsaleni imifanekiso yezinto ezihambayo. Kakade ke, ngophuhliso lwetekhnoloji yeCMOS, iikhamera zemizi-mveliso zeCMOS zikwasetyenziswa koomatshini abaninzi bokubeka iitships. Iikhamera zemizi-mveliso zeCCD zisetyenziswa kakhulu kwicandelo lokuhlola okuzenzekelayo ngokubonakalayo. Iikhamera zemizi-mveliso zeCMOS zisetyenziswa kakhulu ngenxa yexabiso lazo eliphantsi kunye nokusetyenziswa kwamandla okuphantsi.
Iikhamera zemizi-mveliso zisetyenziswa kwimigca yemveliso
②Isisombululo seelensi zekhamera zemizi-mveliso
Okokuqala, isisombululo sikhethwa ngokuqwalasela ukuchaneka kwento ejongwayo okanye elinganiswayo. Ukuba ukuchaneka kwepikseli yekhamera = intsimi yokujonga kwicala elinye ngobukhulu / isisombululo sekhamera sokujonga kwicala elinye, ngoko isisombululo sekhamera sokujonga kwicala elinye = intsimi yokujonga kwicala elinye ubukhulu / ukuchaneka kwethiyori.
Ukuba intsimi enye yokujonga yi-5mm kwaye ukuchaneka kwethiyori yi-0.02mm, isisombululo sendlela enye yi-5/0.02=250. Nangona kunjalo, ukuze kwandiswe uzinzo lwenkqubo, akunakwenzeka ukuhambelana nexabiso lokuchaneka kokulinganisa/ukujonga ngeyunithi enye yephikseli. Ngokubanzi, kunokukhethwa ngaphezulu kwe-4, ngoko ke ikhamera ifuna isisombululo sendlela enye se-1000 kunye ne-1.3 yezigidi zeephikseli.
Okwesibini, xa kujongwa imveliso yeekhamera zemizi-mveliso, isisombululo esiphezulu siluncedo ekujongeni ukuma okanye uhlalutyo kunye nokuqondwa kwesoftware yomatshini. Ukuba yimveliso ye-VGA okanye ye-USB, kufuneka ijongwe kwisikrini, ngoko ke isisombululo sesikrini naso kufuneka siqwalaselwe. Nokuba isisombululo setekhnoloji yombono wemizi-mveliso siphezulu kangakanani naiilensi zekhamera zoshishino, akuyi kuba nengqiqo kangako ukuba isisombululo sesikrini asanele. Isisombululo esiphezulu seekhamera zemizi-mveliso sikwaluncedo xa usebenzisa amakhadi ememori okanye uthatha imifanekiso.
③Isakhelo sekhameraixabisoilensi yekhamera yemizi-mveliso
Xa into elinganiswayo ishukuma, kufuneka kukhethwe ilensi yekhamera yemizi-mveliso enesantya esiphezulu sefreyimu. Kodwa ngokubanzi, okukhona isisombululo siphezulu, kokukhona isantya sefreyimu siphantsi.
④Ukuthelekiswa kweelensi zemizi-mveliso
Ubungakanani betshiphu yenzwa bufanele bube mncinci kunobukhulu belensi okanye bulingane nobukhulu belensi, kwaye i-C okanye i-CS mount nayo mayifane.
2.Okunyeciingcebiso zecukufunxarukukhanyaci-ameralii-ens
①C-khweza okanye khweza i-CS
Umgama wojongano lwe-C-mount yi-17.5mm, kwaye umgama wojongano lwe-CS-mount yi-12.5mm. Ungagxila kuphela xa ukhetha ujongano oluchanekileyo.
Umahluko phakathi kweendawo ezahlukeneyo zokunxibelelana
②Ubungakanani besixhobo esinobushushu bokukhanya
Kwitshiphu ethambileyo ye-2/3-intshi, kuya kufuneka ukhetheilensi yekhamera yemizi-mvelisooko kuhambelana nekhoyili yomfanekiso. Ukuba ukhetha i-1/3 okanye i-1/2 intshi, kuya kuvela ikona enkulu emnyama.
③Khetha ubude befocal
Oko kukuthi, khetha ilensi yemizi-mveliso enombono omkhulu kancinci kunoluhlu lokujonga.
④Ubunzulu bebala kunye nendawo yokukhanyisa kufuneka ihambelane
Kwiindawo ezinokukhanya okwaneleyo okanye ukukhanya okuphezulu, ungakhetha umngxuma omncinci ukuze wonyuse ubunzulu bentsimi uze ngaloo ndlela uphucule ukucaca kokudubula; kwiindawo ezingenakukhanya kwaneleyo, ungakhetha umngxuma omkhulu kancinci, okanye ukhethe itshiphu ethambileyo ene-photosensitive ephezulu.
Ukongeza, ukuze ukhethe ilensi yekhamera efanelekileyo yemizi-mveliso, kufuneka uqwalasele ezinye iindlela ezithandwayo. Umzekelo, izinzwa zemifanekiso zenze inkqubela phambili enkulu kwiminyaka yakutshanje, kunye nomkhwa wokujonga iiphikseli ezininzi ukuphucula isisombululo seiilensi zekhamera zoshishino, kunye nobuntununtunu obuphezulu (izinzwa zomfanekiso ezikhanyiswa ngasemva). Ngaphezu koko, iteknoloji yeCCD iye yasebenza ngakumbi kwaye ngoku yabelana ngemisebenzi emininzi nezinzwa zobuchwepheshe beCMOS.
Iingcinga Zokugqibela:
UChuangAn wenze uyilo lokuqala kunye nokuveliswa kweelensi zekhamera zoshishino, ezisetyenziswa kuzo zonke iinkalo zezicelo zoshishino. Ukuba unomdla okanye uneemfuno zeelensi zekhamera zoshishino, nceda unxibelelane nathi ngokukhawuleza.
