一,WUmnqwazi kukugqwetheka kwilensi kwiFoto?
Ukugqwethwa kweLens ekufotweni kubhekisa kuphambuko lwamehlo okwenzekayo xa ilensi yekhamera isilela ukuvelisa kwakhona ngokuchanekileyo umfanekiso wesifundo esifotwayo. Oku kubangela umfanekiso ogqwethekileyo othi woluliwe okanye ucinezelwe, kuxhomekeke kuhlobo lokugqwesa. Kukho iintlobo ezimbini eziphambili zokugqwethwa kwelensi:ukugqwethwa komphandakwayeukugqwethwa kwepincushion.
Ukugqwetheka komphanda kwenzeka xa imigca ethe tye kufutshane nemiphetho yomfanekiso ibonakala igobela ngaphandle, idala isiphumo sokudumba. Ukugqwetheka kwePincushion, kwelinye icala, kwenzeka xa imigca ethe tye kufutshane nemiphetho yomfanekiso ibonakala igophe ngaphakathi, idala isiphumo esipinkiweyo.
Ukuphazamiseka kweLens kungenzeka ngenxa yezinto ezahlukeneyo ezifana noyilo kunye nokwakhiwa kwelensi, i-engile yokujonga, kunye nomgama phakathi kwekhamera kunye nesihloko. Iqondo lokugqwesa linokwahluka ngokuxhomekeke kwilensi ethile esetyenziswayo kunye noseto olusetyenziswa ngumfoti.
Ngethamsanqa, ukugqwetheka kwelensi kuhlala kulungiswe ngokusebenzisa ubuchule basemva kokulungiswa okanye ngokusebenzisa isoftware ekhethekileyo eyilelwe ukulungisa ukugqwetheka kwelensi. Nangona kunjalo, kusoloko kungcono ukucutha ukugqwetheka kweelensi ngokusebenzisa iilensi ezikumgangatho ophezulu kunye nokuqulunqa ngononophelo izithonga zakho ukunqanda ukugqwetheka okugqithisileyo.
二,Umahluko ekugqwetheni phakathiaiilensi ezingqukuva kunye neelensi ezingqukuva.
Iilensi ze-aspherical kunye ne-spherical lens ziintlobo zeelensi ezibonakalayo ezisetyenziswa kwiikhamera, iiteleskopu, iimicroscopes, kunye nezinye izixhobo zamehlo.
Iilensi ezingqukuvazibe nomphezulu ogobileyo omile njengenxalenye yengqukuva, kwaye zezona ntlobo zixhaphakileyo zelensi. Nangona kunjalo, banokwazisa i-optical aberration efana ne-spherical aberration, coma, kunye nokugqwetheka, ngakumbi xa isetyenziswe kwimingxuma emikhulu okanye kwiilensi ezibanzi.
Iilensi zeAspherical, kwelinye icala, inomphezulu ongeyo-spherical owenzelwe ukulungisa oku kuphambuka. Oku kuvumela imifanekiso ebukhali ngokuchasa ngcono kunye nokunciphisa ukugqwetheka, ngakumbi kwimiphetho yesakhelo. Iilensi ze-aspherical zihlala zisetyenziswa kwiilensi eziphezulu, kwaye zinokufumaneka kuzo zombini iilensi eziphambili kunye ne-zoom.
Ngokubanzi, ukusetyenziswa kweelensi ze-aspherical kunokunceda ukuphucula ukusebenza kwe-lens ye-optical, ngokukodwa malunga nokunciphisa ukuphazamiseka kunye nokunye ukuphazamiseka. Nangona kunjalo, iilensi ze-aspherical zihlala zibiza kakhulu ukwenza iilensi ezingqukuva, ezinokuzenza zibiza kakhulu kubathengi.
三,Wumnqwazi yi-engile ebanzi ephantsi yokuphazamiseka kwelensi?
A i-lens ebanzi ephantsi yokuphazamisekaluhlobo lwekhamera yekhamera evumela indawo ebanzi yokujonga ngaphezu kwe-lens eqhelekileyo ngelixa unciphisa okanye uphelise ukuphambuka okunokuthi kwenzeke nge-wide-angle lens.
Iilensi ezibanziinobude obufutshane bokujongwa kuneelensi eziqhelekileyo kwaye inokubamba indawo eninzi kwisakhelo esinye, ibenze badume ngobume belizwe, ulwakhiwo, kunye nokufota kwangaphakathi. Nangona kunjalo, ngenxa ye-engile ebanzi yembono, ziyakwazi ukuvelisa ukugqwesa, okunokubangela ukuba imigca ethe tye ibonakale igobile okanye izinto ezibonakala zoluliwe okanye zigqwethiwe.
Iilensi ezisezantsi ezigqwethekileyoziyilelwe ukunciphisa okanye ukuphelisa oku kugqwetha, ukuvumela umboniso ochanekileyo nowokwenene wendawo. Ezi lens zidla ngokusetyenziswa ngabafoti abaqeqeshiweyo abafuna indawo ebanzi yokujonga ngaphandle kokubeka esichengeni umgangatho womfanekiso okanye ukuchaneka.
四,Wumnqwazi sesona sicelo siphambili se-M12 i-lens yokuphazamiseka ephantsi?
II-lens ye-M12 ephantsi yokuphazamisekaisetyenziswa ngokuqhelekileyo kumbono womatshini kunye nezicelo zombono wekhompyutheni, ngokukodwa kwiikhamera kunye neenkqubo zokucinga ezifuna imifanekiso ekumgangatho ophezulu kunye nokuphazamiseka okuncinci. Nazi ezinye zezicelo eziphambili ze-M12 iilensi zokuphazamiseka okuphantsi:
I-Automation ye-Industrialn: Iilensi ze-M12 eziphantsi eziphazamisayo zisetyenziselwa kwiinkqubo zokuzenzekelayo zoshishino ukubamba imifanekiso ecacileyo nechanekileyo yezinto kwiinkqubo zokuvelisa.
Iirobhothi: Izicelo zerobhothi zihlala zisebenzisa i-M12 iilensi eziphambukayo eziphantsi zokubona okubonakalayo kunye neenkqubo zokukhokela ezifuna ukuchaneka okuphezulu kunye nokuchaneka.
Ukhuseleko kunye nokuBekwa kweliso: Iilensi eziphantsi ze-M12 eziphazamisayo zisetyenziswa ngokuqhelekileyo kwiikhamera zokhuseleko kunye neenkqubo zokujonga ukubamba imifanekiso ecacileyo nechanekileyo yabantu kunye nezinto.
Imifanekiso yezoNyango: Iilensi eziphantsi ze-M12 eziphazamisayo zikwasetyenziswa kwiinkqubo zokucinga zonyango kwiinjongo zokuxilonga kunye nophando.
Iimoto: Iilensi eziphantsi ze-M12 eziphazamisayo zisetyenziswa kwiinkqubo zokuncedisa umqhubi ophezulu (ADAS) kwizithuthi, ezifana neenkqubo zokulumkisa ukuhamba kwendlela kunye neenkqubo zokuphepha ukungqubana.
Ngokubanzi, i-lens ye-M12 ephantsi yokuphazamiseka sisixhobo esiguquguqukayo saso nasiphi na isicelo esifuna umfanekiso okumgangatho ophezulu kunye nokuphazamiseka okuncinci.
