Iindlela zokukhetha kunye neendlela zokuhlelwa ze-lenses yombono

I-Matshini yoMbono weLensiNgaba iilensi zenzelwe ukusetyenziswa kweenkqubo zombono zomatshini, ezikwabizwa ngokuba zii-lensed zekhamera yezamashishini. Iinkqubo zombono wamatshini zihlala ziquka iikhamera zeshishini, iilensi, imithombo yokukhanya, kunye nesoftware yokulungisa umfanekiso.

Zisetyenziselwa ukuqokelela ngokuzenzekelayo, qhubela phambili, kunye nokuhlalutya imifanekiso ukuze ugwebe umgangatho wokusebenza ngokuzenzekelayo okanye ugqibezele imilinganiselo ye-Preciese ngaphandle konxibelelwano. Zihlala zisetyenziselwa ukulinganisa okucocekileyo, iNdibano yokuSebenza eZenzekelayo, uvavanyo olungenakuqhekeka, ukufumanisa isiphene, ukuhamba kwerobhothi kunye nezinye iinkalo ezininzi.

1.Yintoni omele uyiqwalasele xa ukhetha iilensi zombono womatshini?

Xa ukhethaIminwe yombono wamatshini, kufuneka uqwalasele izinto ezahlukeneyo zokufumana ilensi elungele wena. Ezi zinto zilandelayo ziqwalaselwa ngokuqhelekileyo:

Intsimi yembono (i-FOV) kunye nomgama wokusebenza (WD).

Intsimi yembono kunye nokusebenza komgama chaza indlela enkulu onokuyibona kunye nomgama osuka kwilensi ukuya kwinto.

Uhlobo lwekhamera ehambelanayo kunye nosayino.

Ilensi oyikhethayo kufuneka ihambelane nekhombonakalo yakho yekhamera, kwaye umfanekiso ogcweleyo weelensi kufuneka ube mkhulu okanye ulingana nomgama we-diagonar.

I-Beam ye-Beam yeBeam.

Kuyimfuneko ukucacisa ukuba isicelo sakho sifuna ukugqwetha okuphantsi, isisombululo esiphezulu, ubunzulu obukhulu okanye ubunzulu beelensi ezinkulu okanye ubunzulu belensi.

Ubungakanani bento kunye nezakhono zokusombulula.

Inkulu kangakanani into ofuna ukuyibona kunye nokuba sisonjululwa njani isisombululo esifunekayo ukuze sicace, nto leyo emisela ukuba ichaza ukuba inkulu kangakanani inkangeleko kwaye zingaphi iipikseli zekhamera oyifunayo.

Eiimeko zentsholongwane.

Ukuba unemifuno ekhethekileyo yendalo esingqongileyo, enjengokuyothusa, uthuli okanye amanzi, kuya kufuneka ukhethe ilensi enokuthi ifezekise ezi mfuno.

Uhlahlo-lwabiwo mali.

Luhlobo luni lweendleko onokuthi uzihlawule ziya kuchaphazela i-lens brand kunye nemodeli oyikhethayo ekugqibeleni.

Uphawu lombono

2.Indlela yokuhlela ye-lenses yomatshini

Zininzi izinto ekufuneka ziqwalaselwe xa ukhetha iilensi.Iminwe yombono wamatshiniInokwahlulwa kwiintlobo ezahlukeneyo ngokwemigangatho eyahlukeneyo:

Ngokohlobo olugxile kubude obubi, lunokwahlulwa ukuba: 

I-Lens ekugxilwe kuzo

Ngokutsho kohlobo lwe-aperture, inokohlulwa ibe: 

I-Apert Aperture Lens (i-aperture kufuneka ihlengahlengiswe ngesandla), ilensi ye-adrture ezenzekelayo (iilensi zinokulungelelanisa ngokuzenzekelayo i-aperture ngokwesikhanyiso esihle).

Ngokweemfuno zokucinga zokucinga, iyahlulahlulwa ibe: 

Iilensi ezisemgangathweni eziMiselweyo (ezifanelekileyo ukucinga ngokwengcinga ngokubanzi ezifana nokuhlolwa okuqhelekileyo kunye nokuhlolwa komgangatho), iilensi ezisemgangathweni), iilensi eziphezulu (i-lenses ePhakamileyo (efanelekileyo ekubhaleni ngokuchanekileyo, ukucinga okuphezulu kunye nezinye iimfuno eziphezulu zokusombulula).

Ngokutsho kwesayizi yenzwayo, inokwahlulwa ibe: 

I-lenser encinci ye-sersor (ilungele izinzwa ezincinci ezifana ne-1/4 ", 1/2", 1/2 ", njl. Njl. , njl njl.

Ngokwemo yengcinga, inokwahlulwa ibe: 

I-Monochrome icinga ilensi (inokuphela kuphela ifake imifanekiso emnyama kunye nemhlophe), imibala yengcinga yelensi (inokufaka imifanekiso yemibala).

Ngokweemfuno zomsebenzi eziphezulu, ziyahlulwa ukuba:I-lenses ephantsi.
