Yintoni i-Fisheye Lens kunye neentlobo ze-Fisheye Effects

Ilensi ye-fisheye yilensi ebanzi ngokugqithisileyo, ekwabizwa ngokuba yi-panoramic lens.Ngokuqhelekileyo kucingwa ukuba ilensi enobude obuyi-16mm okanye ubude obufutshane bogxininiso yilensi ye-fisheye, kodwa kubunjineli, ilensi enoluhlu lokujonga olungaphezulu kwe-140 ngokudibeneyo ibizwa ngokuba yilensi ye-fisheye.Ukuqhuba, kukho iilensi ezineengile zokujonga ezidlula okanye zide zifikelele kuma-270 degrees.I-lens ye-fisheye liqela lokukhanya elichasene ne-telephoto elinokuphazamiseka okuninzi komgqomo.I-lens yangaphambili yale lens ihamba phambili ngokulandelelana, kwaye imilo ifana neso lentlanzi, ngoko ke igama elithi "fisheye lens", kwaye imbonakalo yayo ifana neyentlanzi ejonga izinto phezu kwamanzi.

I-lens ye-fisheye ixhomekeke ekwaziseni ngokwenziwa umyinge omkhulu wokugqwethwa komphanda ukufumana i-angle enkulu yokujonga.Ngoko ke, ngaphandle kwento esembindini womfanekiso, amanye amalungu afanele ukuba yimigca ethe tye abe nokugqwetheka okuthile, Okukhokelela kwizithintelo ezininzi kwisicelo sayo.Ngokomzekelo, kwibala lokhuseleko, i-lens ye-fisheye inokubuyisela iilensi ezininzi eziqhelekileyo ukujonga uluhlu olubanzi.Kuba i-engile yokujonga inokufikelela kwi-180º okanye ngaphezulu, akukho phantse i-engile efileyo yokubeka iliso.Nangona kunjalo, ngenxa yokuphazamiseka komfanekiso, into enzima ukuba iqondwe ngeliso lomntu, elinciphisa kakhulu ukukwazi ukubeka iliso;Omnye umzekelo ukwintsimi yerobhothi, iirobhothi ezizenzekelayo ziyafuneka ukuba ziqokelele ulwazi lwemifanekiso yeziganeko ezingqongileyo kwaye zichonge ukuba zithathe amanyathelo ahambelanayo.Ukuba i-lens ye-fisheye isetyenzisiweyo, ukuqokelela ngokufanelekileyo kunokunyuswa ngamaxesha angama-2-4, kodwa ukuchithwa kwenza kube nzima ukuchonga isofthiwe.Ngoko ke siwubona njani umfanekiso kwilensi ye-fisheye?I-algorithm inikezelwa ukuchonga izikhundla zezinto ezikumfanekiso.Kodwa kukwanzima ukuqonda ukuqondwa kwemizobo entsonkothileyo ngenxa yobunzima bokubala kwesoftware.Ngoko ke, indlela eqhelekileyo ngoku kukuphelisa ukuphazamiseka kumfanekiso ngokusebenzisa uluhlu lweenguqu, ukuze ufumane umfanekiso oqhelekileyo uze uchonge.

Ubudlelwane phakathi kwesangqa somfanekiso kunye nenzwa yome ngolu hlobo lulandelayo:

Ekuqaleni, iilensi ze-fisheye zazisetyenziselwa kuphela ukufota ngenxa ye-aesthetics yazo ekhethekileyo ngenxa yokuphazamiseka kombhobho abakwenzayo ngexesha lenkqubo yokucinga.Kwiminyaka yakutshanje, ukusetyenziswa kwe-lens ye-fisheye ngokuqhelekileyo isetyenziswa kwibala lokucinga nge-angle-angle ebanzi, umkhosi, ucupho, ukulinganisa kwe-panoramic, ukuboniswa kwe-spherical kunye nokunye.Xa kuthelekiswa nezinye iilensi, i-lens ye-fisheye ineenzuzo zobunzima bokukhanya kunye nobukhulu obuncinci.
