Ubude bojoliso yiparamitha ebalulekileyo elinganisa iqondo lokuhlangana okanye ukwahluka kwemitha yokukhanya kwiinkqubo zokukhanya. Le parameter idlala indima ebalulekileyo ekumiseleni indlela umfanekiso owenziwe ngayo kunye nomgangatho walo mfanekiso. Xa imitha ye-parallel idlula kwi-lens egxile kwi-infinity, idibana kwindawo ekugxilwe kuyo, echazwa njengomgama ukusuka kumbindi we-optical we-lens ukuya kweli nqanaba. Indawo ekugxilwe kuyo kulapho imitha yokukhanya idibana khona emva kokudlula kwi-lens, yenza umfanekiso obukhali. Ukufezekisa umfanekiso obukhali wento kwi-infinity, i-lens kufuneka ibekwe ngakumbi ukusuka kwinqwelo-moya. Olu hlengahlengiso luchaza ukuba kutheni iilensi ezininzi zanda ngobude xa umsesane wogxininiso ujikeleziswa, ukuvumela ukugxila ngokuchanekileyo kwizinto ezikude.
Kwizixhobo ze-optical, i-field of view angle (i-FOV) ibhekisela kumlinganiselo we-angular wendawo ebonakalayo ebanjwe yi-lens, kunye ne-lens esebenza njenge-apex yale angle. I-engile ye-FOV ibalulekile kuba imisela ubungakanani bendawo enokubonwa. I-angle ye-FOV enkulu iphumela kumhlaba obanzi wokujonga, ibamba ngaphezulu kokusingqongileyo okusingqongileyo kodwa ngokwandisa okusezantsi. Ngakolunye uhlangothi, ukuba into ekujoliswe kuyo idlula le engile, ayiyi kungena ngokupheleleyo kwintsimi ye-lens, ekhokelela kwimifanekiso engaphelelanga okanye ephosakeleyo. Umzekelo, ekufotweni kwezilwanyana zasendle, iFOV emxinwa inokubangela ukuba iindawo ezilahlekileyo zesilwanyana okanye indawo ezisingqongileyo, ngelixa iFOV ebanzi inokuthi ibambe iinkcukacha ezininzi ngasemva, inciphisa ukubaluleka kwesifundo.
Phantsi kweemeko eziqhelekileyo, i-engile ye-FOV kunye nobude befocal zilungelelene ngokuphambeneyo. Obu budlelwane buthetha ukuba ubude bogxininiso obufutshane buhambelana nee-engile ezinkulu ze-FOV, ngelixa ubude be-focal ubude bukhokelela kwii-engile ze-FOV ezincinci. Iilensi zeTelephoto, ezinobude obude bokujolisa, zilungele ukubeka iliso kude kunye nemisebenzi yokudubula efuna ukubamba izinto ezikude kwiinkcukacha eziphezulu. Ezi lens zisetyenziswa ngokubanzi kwizicelo ezahlukeneyo ezifana nokhuseleko lwasezidolophini, ulawulo lwetrafikhi, iliso lomda kunye nonxweme lokhuselo, ukufotwa kwezilwanyana zasendle, kunye namaxwebhu omnyhadala wezemidlalo. Umzekelo, iilensi zetelephoto eziyilwe kwaye zenziwe yiJinyuan Optics, ezinobude obugxile ukusuka kwi-30-120mm, 5-50mm, kunye ne-10-50mm, zinokuzalisekisa ezi mfuno. Ezi lens zibonelela ngokusebenza okugqwesileyo ekuthatheni imifanekiso eneenkcukacha yezifundo ezikude, zizenze zibe zizixhobo eziyimfuneko kwiingcali kwezi nkalo. Ukongeza, iJinyuan Optics ibonelela ngeelensi ezincinci ezinobude bokujolisa ubude, obufana ne-1/2.7" 3MP 50mm kunye ne-1/1.8" 5MP 25mm iimodeli, ezidibanisa uyilo olubambeneyo kunye nesakhono sokucinga esinamandla.
Ngokuchasene noko, iilensi zojoliso olufutshane, ezikwabizwa ngokuba ziilensi ezibanzi, zibonelela ngommandla obanzi wokujonga ngenxa yee-engile zazo ezinkulu ze-FOV. Olu phawu lubenza bafaneleke ngakumbi ukubeka esweni iindawo ezinkulu ezingenazo iindawo ezingaboniyo, njengokhuseleko kwizikwere, kwiindawo zokugcina iimpahla, kwizikhululo zeenqwelomoya, nakwizikhululo. Iilensi ezinobubanzi obubanzi zinokubamba imiboniso ebanzi, ziqinisekise ukugqunywa ngokubanzi kwendawo ebekwe esweni. I-Jinyuan Optoelectronics 'yamva nje ye-1/2.5-intshi, i-1.8mm ekugxilwe kuyo ubude obufutshane-i-lens yogxininiso ibonisa intsimi ebanzi yokujonga, isisombululo esiphezulu se-pixel, kunye neempawu zokungena kwamanzi, ezithi ngokudibeneyo zibe negalelo ekusebenzeni kwayo okuphezulu. Indawo ebanzi yokujonga ivumela i-lens ukuba ibambe indawo enkulu kwisakhelo esinye, ngelixa isisombululo esiphezulu se-pixel siqinisekisa ukuba iinkcukacha zicacile kwaye zichazwe kakuhle. Uyilo olungenamanzi luyenza ilungele ukusetyenziswa ngaphandle, nakwimeko yemozulu embi. Ngenxa yoko, le lensi isetyenziswa ngokubanzi kwiintsimbi zokujonga umnyango, iinkqubo zokubeka iliso zokhuseleko, kunye neekhamera zeemoto, ezibonelela ngezisombululo ezinokwethenjelwa kunye neziphezulu zemifanekiso yezicelo ezahlukeneyo.
Isishwankathelo, ubude be-focal kunye ne-FOV angle zimbini iiparamitha eziphambili ezichaphazela kakhulu ukusebenza kweenkqubo zokukhanya. Ukuqonda ubudlelwane babo kunye nokukhetha uhlobo olufanelekileyo lwelensi esekwe kwiimfuno ezithile kunokuphucula kakhulu ukusebenza kwemifanekiso kunye nokubeka iliso kumashishini ahlukeneyo. Nokuba kukuthatha izinto ezikude ngeenkcukacha eziphezulu okanye ukujonga iindawo ezinkulu ngokupheleleyo, ukhetho olufanelekileyo lwelensi lunokwenza umahluko omkhulu ekuphumezeni iziphumo ezizezona zilungileyo.
