Iindlela zokuKhetha kunye noHlelo lweeLensi zoMbono woMatshini

Ilensi yombono womatshiniyilensi eyenzelwe ukusetyenziswa kwiinkqubo zokubona koomatshini, ekwaziwa ngokuba ziilensi zekhamera yeshishini. Iinkqubo zokubona ngoomatshini zihlala zineekhamera zemizi-mveliso, iilensi, imithombo yokukhanya, kunye nesoftware yokulungisa imifanekiso.

Zisetyenziselwa ukuqokelela ngokuzenzekelayo, ukucubungula, kunye nokuhlalutya imifanekiso ukugweba ngokuzenzekelayo umgangatho weendawo zokusebenza okanye ukugqiba imilinganiselo echanekileyo yendawo ngaphandle koqhagamshelwano. Zihlala zisetyenziselwa ukulinganisa okuchanekileyo, ukudibanisa okuzenzekelayo, uvavanyo olungonakalisi, ukufumanisa isiphene, ukukhangela i-robot kunye nezinye iindawo ezininzi.

1.Yintoni omele uyiqwalasele xa ukhetha iilensi zemboniselo yomatshini?

Xa ukhethaiilensi zombono womatshini, kufuneka uqwalasele izinto ezahlukeneyo ukuze ufumane i-lens efanele wena. Le miba ilandelayo yingqwalasela eqhelekileyo:

Indawo yokujonga (FOV) kunye nomgama wokusebenza (WD).

Indawo yokujonga kunye nomgama wokusebenza umisela ukuba inkulu kangakanani into oyibonayo kunye nomgama ukusuka kwilensi ukuya kwinto.

Uhlobo lwekhamera oluhambelanayo kunye nobungakanani boluvo.

Ilensi oyikhethayo kufuneka ihambelane nojongano lwekhamera yakho, kwaye umfanekiso ogobileyo welensi kufuneka ube mkhulu okanye ulingane nomgama wediagonal wesixhobo soluvo.

Umqa wesiganeko odluliselweyo.

Kuyimfuneko ukucacisa ukuba ingaba isicelo sakho sifuna ukugqwetheka okuphantsi, ukusonjululwa okuphezulu, ubunzulu obukhulu okanye uqwalaselo lwelensi yokuvula enkulu.

Ubungakanani bento kunye nezakhono zokusombulula.

Inkulu kangakanani into ofuna ukuyibhaqa kwaye ilungile kangakanani isisombululo kufuneka icace, nto leyo emisela ukuba inkulu kangakanani indawo yokujonga kwaye zingaphi iipixels zekhamera ozidingayo.

Eiimeko zokusingqongileyo.

Ukuba uneemfuno ezikhethekileyo zokusingqongileyo, ezifana no-shockproof, uthuli okanye ukungangeni kwamanzi, kufuneka ukhethe i-lens enokuthi ihlangabezane nezi mfuno.

Uhlahlo lwabiwo-mali lweendleko.

Luhlobo luni lweendleko onokuthi ufikelele kuzo luya kuchaphazela uphawu lwelensi kunye nomzekelo owukhethayo ekugqibeleni.

2.Indlela yokwahlula iilensi zombono womatshini

Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha iilensi.Iilensi zokubona ngomatshiniinokwahlulwa ngokweendidi ezahlukeneyo ngokwemigangatho eyahlukeneyo:

Ngokohlobo lobude bojoliso, lunokwahlulwa lube: 

I-lens yogxininiso esisigxina (ubude obugxininise bugxininisekile kwaye abunakuhlengahlengiswa), i-zoom lens (ubude obugxilwe buyahlengahlengiswa kwaye umsebenzi uyabhetyebhetye).

Ngokohlobo lokuvula, lunokwahlulwa lube: 

I-lens yokuvula i-Manual (i-aperture idinga ukulungiswa ngesandla), i-lens yokuvula i-automatic (i-lens inokulungelelanisa ngokuzenzekelayo i-aperture ngokokukhanya kwe-ambient).

Ngokweemfuno zesisombululo somfanekiso, inokwahlulwa ibe: 

Iilensi zesisombululo esisemgangathweni (ezifanelekileyo kwiimfuno ze-imaging jikelele ezifana nokubeka iliso okuqhelekileyo kunye nokuhlolwa komgangatho), iilensi ezichanekileyo (ezilungele ukuchongwa ngokuchanekileyo, ukulinganisa ngesantya esiphezulu kunye nezinye izicelo ezineemfuno eziphezulu zesisombululo).

Ngokobungakanani boluvo, inokwahlulwa ibe: 

Iilensi zefomati yoluvo oluncinci (zilungele abenzi boluvo abancinci abanje nge 1/4 ″, 1/3 ″, 1/2 ″, njalo njalo), iilensi zefomathi yesivamvo esiphakathi (zilungele abenzi boluvo abanobungakanani obuphakathi njenge 2/3 ″, 1″ , njl. inzwa), iilensi zefomathi yenzwa enkulu (ye-35mm i-full-frame okanye i-sensor enkulu).

Ngokwendlela yomfanekiso, inokwahlulwa ibe: 

I-monochrome imaging lens (inokuthi ithathe kuphela imifanekiso emnyama nemhlophe), i-lens yomfanekiso wombala (inokuthi ibambe imifanekiso yemibala).

Ngokweemfuno ezikhethekileyo zokusebenza, inokwahlulwa ibe:iilensi zokuphazamiseka okuphantsi(ezinokunciphisa impembelelo yokuphazamiseka kumgangatho womfanekiso kwaye zifanelekile kwiimeko zesicelo ezifuna umlinganiselo ochanekileyo), iilensi ezichasene ne-vibration (ezifanelekileyo kwiindawo zoshishino kunye neengqungquthela ezinkulu), njl.
