Kwicandelo le-automation yemizi-mveliso, iikhamera kunye neelensi zizinto ezibalulekileyo zokujonga nokuchonga ngokubonakalayo. Njengesixhobo esingaphambili sekhamera, ilensi inefuthe elibalulekileyo kumgangatho wokugqibela womfanekiso wekhamera.
Iindidi ezahlukeneyo zelensi kunye noseto lweeparameter ziya kuba nefuthe ngqo ekucaceni komfanekiso, ubunzulu bentsimi, isisombululo, njl. Ke ngoko, ukukhetha ilensi efanelekileyo kwiikhamera zoshishino sisiseko sokufikelela ekuhlolweni okubonakalayo okusemgangathweni ophezulu.
1.Uhlu lweelensi zekhamera zoshishino
Iingcaliiilensi zekhamera zoshishinozingahlulwa zibe ziindidi ezilandelayo:
(1)Ilensi yokugxila ezinzileyo
Ilensi yokugxila esisigxina lolona hlobo lwelensi lusetyenziswa kakhulu kwiikhamera zoshishino. Inobude obuthile bokugxila kunye noluhlu lokudubula oluzinzileyo. Ifanelekile ekumiseleni umgama kunye nobukhulu bendawo ekujoliswe kuyo. Ngokulungisa umgama wokudubula, ubungakanani obahlukeneyo beendawo zokudubula bunokufikelelwa.
(2)Ilensi yeTelecentric
Ilensi yeTelecentric luhlobo olukhethekileyo lwelensi yekhamera yemizi-mveliso enendlela ende yokukhanya, enokufikelela kubunzulu obukhulu bentsimi kunye nesiphumo sokudubula esicacileyo. Olu hlobo lwelensi lusetyenziswa kakhulu kwiinkqubo zokuhlola ezibonakalayo ezichanekileyo nezizinzileyo, ezifana nombono womatshini, ukulinganisa ngokuchanekileyo kunye nezinye iindawo.

(3)Ilensi yokuskena umgca
Ilensi yokuskena umgca yilensi yokuskena ekhawulezayo esetyenziselwa iikhamera zokuskena umgca okanye iikhamera ze-CMOS. Ingafikelela ekuskenweni komfanekiso ngesantya esiphezulu nangokuchanekileyo kwaye ifanelekile ukuhlolwa komgangatho kunye nokuchongwa kwemigca yemveliso ekhawulezayo.
(4)Ilensi yeVarifocal
Ilensi ye-varifocal yilensi enokutshintsha ukwandiswa. Ingatshintsha umlinganiselo wokukhanya ngokweemfuno ezahlukeneyo zokuhlolwa ngokulungelelanisa ukwandiswa. Ifanelekile ukuvavanywa kweendawo ezichanekileyo, uphando lwesayensi kunye nezinye iimeko.
Ngokukhetha uhlobo lwelensi kunye noseto lweeparameter ezifanelekileyo kwikhamera, ungafumana iziphumo zomfanekiso ezikumgangatho ophezulu kunye neziphumo ezichanekileyo zokuhlolwa kombono. Kwangaxeshanye, usebenzisa umgangatho ophezulu kunye nozinzo oluphezulu.iilensi zekhamera zoshishinoinokuphucula ukusebenza kakuhle kwemveliso kwaye inciphise iindleko zokugcina izinto zisebenza kakuhle.
Ngoko ke, kwabo babandakanyeka ekuboneni koomatshini nasekucwangcisweni kwemifanekiso, kubaluleke kakhulu ukuqonda nokuqonda iintlobo, imigaqo yokukhetha kunye neendlela zokusebenzisa iilensi zekhamera zoshishino.
2.Imigaqo yokukhetha iilensi zekhamera zoshishino
(1)Ukugqiba ukuba ukhethe ingqwalasela esisigxina okanyevilensi ye-arifocal
Iilensi ezigxile kwi-fixed-focus zineengenelo zokuphambuka okuncinci kunye nokusebenza okubiza kakhulu, kwaye zisetyenziswa kakhulu kwiinkqubo zokuhlola ngokubona. Nangona kunjalo, kwezinye iimeko apho intsimi yokujonga kufuneka itshintshwe, iilensi ze-zoom ziyindlela yokukhetha.
Ngexesha lenkqubo yokwenziwa kwemifanekisoumbono womatshiniInkqubo, kuyimfuneko ukumisela ukuba ingaba ukukhulisa kufuneka kutshintshwe na. Ukuba kunjalo, kufuneka kusetyenziswe ilensi ye-varifocal. Ngaphandle koko, ilensi egxile kwi-fixed-focus ingahlangabezana neemfuno.

(2)Misela umgama wokusebenza kunye nobude be-focal
Umgama wokusebenza kunye nobude befocal buhlala buqwalaselwa kunye. Ngokubanzi, isisombululo senkqubo simiselwa kuqala, kwaye ukwandiswa kufumaneka ngokudibanisa ubungakanani bepikseli yekhamera yemizi-mveliso.
Umgama onokwenzeka womfanekiso ekujoliswe kuwo uyaziwa ngokuhlanganisa imida yesakhiwo sendawo, kwaye ubude befocal kunye nobude belensi yekhamera yemizi-mveliso buqikelelwa ngakumbi. Ke ngoko, ubude befocal belensi yekhamera yemizi-mveliso bunxulumene nomgama wokusebenza kunye nesisombululo sekhamera yemizi-mveliso.
(3)Iimfuno zomgangatho womfanekiso
Kwizicelo zokubona koomatshini, abathengi abahlukeneyo bafuna ukuchaneka okwahlukileyo kokufumanisa, kwaye umgangatho womfanekiso ohambelanayo unokwahluka. Xa ukhetha ilensi yekhamera yemizi-mveliso, ubungakanani bomfanekiso kufuneka buhambelane nobukhulu bomphezulu obonakalayo wekhamera yemizi-mveliso, kungenjalo umgangatho womfanekiso webala lokujonga elingaphandle awunakuqinisekiswa.
Kwiindlela zokulinganisa umbono womatshini, umgangatho womfanekiso unxulumene nesisombululo, izinga lokuphambuka kunye nokuphambuka kwelensi yemizi-mveliso.
(4)Imbobo kunye nojongano
Ukuvulwa kweiilensi zekhamera zoshishinoIchaphazela kakhulu ukukhanya komphezulu womfanekiso, kodwa kwimbono yomatshini yangoku, ukukhanya komfanekiso wokugqibela kuxhomekeka kwizinto ezininzi ezifana nokuvuleka, amasuntswana ekhamera, ixesha lokudibanisa, umthombo wokukhanya, njl. Ke ngoko, ukuze ufumane ukukhanya komfanekiso okufunekayo, kufuneka amanyathelo amaninzi okulungisa.
Ujongano lwelensi lwekhamera yemizi-mveliso lubhekisa kujongano lokufakelwa phakathi kwekhamera kunye nelensi yekhamera. Ezi zimbini kufuneka zihambelane. Ukuba azikwazi ukufana, kufuneka kuqwalaselwe ukuguqulwa.
Ukukhethwa kweelensi zemizi-mveliso
(5)Ngaba kufuneka ilensi ye-telecentric?
Xa kujongwa ukuba into ehlolwayo ityebile na, nokuba kufuneka kuhlolwe iindawo ezininzi, nokuba into leyo inomngxuma, nokuba into leyo yimveliso enamacala amathathu, nokuba into leyo ikumgama ongalinganiyo ukusuka kwilensi, njl.njl., ukusebenzisa iilensi zekhamera zemizi-mveliso eqhelekileyo kwezi meko kuya kuvelisa i-parallax, nto leyo ekhokelela kwiziphumo zohlolo ezingachanekanga.
Ngeli xesha, ukusetyenziswa kweelensi zemizi-mveliso ezisebenzisa i-telecentric kunokusombulula ngempumelelo ezi ngxaki. Ukongeza, iilensi ezisebenzisa i-telecentric azinasiphazamiso siphezulu kunye nobunzulu obukhulu bentsimi, kwaye kwangaxeshanye, zinobuchane obuphezulu bokuhlolwa kunye nokuchaneka okungcono.
Iingcinga Zokugqibela:
