A i-fisheye lensiyilensi ye-engeli ebanzi ngokwedlulele, eyaziwa nangokuthi ilensi yepanoramic. Ngokuvamile kucatshangelwa ukuthi ilensi enobude obugxilwe obungu-16mm noma ubude bokugxila obufushane buyilensi ye-fisheye, kodwa kwezobunjiniyela, ilensi enebanga lokubuka elingaphezu kwamadigri angu-140 ngokuhlangene ibizwa ngokuthi ilensi ye-fisheye. Ekusebenzeni, kukhona namalensi anama-engeli wokubuka adlula noma afinyelele ngisho nangama-270 degrees. Ilensi ye-fisheye iyiqembu lokukhanya kwe-anti-telephoto elinokuhlanekezela okuningi kwemiphongolo. I-lens yangaphambili yale lens iphumele ngaphambili ngokuphambene, futhi ukuma kufana neso lenhlanzi, yingakho igama elithi "fisheye lens", futhi umphumela wayo wokubuka ufana nowenhlanzi ebuka izinto ngaphezu kwamanzi.
Ilensi ye-fisheye
Ilensi ye-fisheye incike ekwethuleni ngokuzenzisa inani elikhulu lokuhlanekezelwa komgqomo ukuze ithole i-engeli enkulu yokubuka. Ngakho-ke, ngaphandle kwento emaphakathi nesithombe, ezinye izingxenye okufanele zibe imigqa eqondile zinokuhlanekezela okuthile, Okuholela emikhawulweni eminingi ekusetshenzisweni kwayo. Isibonelo, emkhakheni wezokuphepha, ilensi ye-fisheye ingangena esikhundleni samalensi amaningi ajwayelekile ukuze igade ububanzi. Njengoba i-engeli yokubuka ingafinyelela ku-180º noma ngaphezulu, cishe ayikho i-engeli efile yokuqapha. Kodwa-ke, ngenxa yokuhlanekezelwa kwesithombe, into inzima ukubonwa ngeso lomuntu, okunciphisa kakhulu ikhono lokuqapha; Esinye isibonelo sisemkhakheni wamarobhothi, amarobhothi azishintshayo adingeka ukuthi aqoqe ulwazi lwezithombe zezigcawu ezizungezile futhi azikhombe ukuze enze izenzo ezihambisanayo.
Uma ai-fisheye lensisetshenziswa, ukusebenza kahle kweqoqo kunganyuswa izikhathi ezi-2-4, kodwa ukuphambuka kwenza isoftware ibe nzima ukuyibona. Ngakho-ke sibona kanjani isithombe esivela kwilensi ye-fisheye? I-algorithm inikezwa ukukhomba izindawo zezinto ezisesithombeni. Kodwa futhi kunzima ukuqaphela ukuqashelwa kwehluzo eziyinkimbinkimbi ngenxa yobunkimbinkimbi bekhompyutha yesofthiwe. Ngakho-ke, indlela evamile manje ukuqeda ukuhlanekezela esithombeni ngokusebenzisa uchungechunge lwezinguquko, ukuze uthole isithombe esivamile bese usikhomba.
Izithombe ze-Fisheye azilungiswanga futhi zilungisiwe
Ubudlelwano phakathi kwesiyingi sesithombe nenzwa bumi kanje:
Ubudlelwano phakathi kwesiyingi sesithombe nenzwa
Ekuqaleni,amalensi ezinhlanzizazisetshenziswa kuphela ezithombeni ngenxa yobuhle bazo obukhethekile ngenxa yokuhlanekezelwa komgqomo abakudalayo ngesikhathi sokuthwebula izithombe. Eminyakeni yamuva nje, ukusetshenziswa kwelensi ye-fisheye bekuvame ukusetshenziswa emkhakheni we-wide-angle imaging, impi, ukubhekwa, ukulingisa kwe-panoramic, ukuqagela okuyindilinga nokunye. Uma kuqhathaniswa namanye ama-lens, i-lens ye-fisheye inezinzuzo zesisindo esilula nosayizi omncane.
