A I-Fisheye Lensiyilensi ebanzi ebanzi, eyaziwa nangokuthi i-lens panoramic. Ngokuvamile kubhekwa ukuthi ilensi enobude obugxile ku-16mm noma ubude obugxilisiwe yi-lens ye-fisheye, kodwa ubunjiniyela, ilensi enobubanzi be-angle bokubuka ama-degree angaphezu kuka-140 ibizwa nge-fisheye lens. Empeleni, kukhona namalensi anokubuka ama-engeli adlula noma afinyelele ama-degree angama-270. I-lens ye-fisheye yiqembu elikhanyayo le-anti-telephoto eline-barrel eningi. Ilensi yangaphambili yale lens ivela ngaphambili, futhi ukwakheka kufana neso lezinhlanzi, yingakho igama elithi "fisheye lens", futhi umphumela waso we-fisheye ", futhi umphumela wawo wokubuka ufana nokwezinhlanzi ezibona ngaphezu kwamanzi.
I-fisheye lens
I-lens ye-fisheye ithembela ngokungenisa imali enkulu yokuhlanekezela umthere ukuze uthole i-angle yokubuka enkulu. Ngakho-ke, ngaphandle kwento enkabeni yesithombe, ezinye izingxenye okufanele zibe nemigqa eqondile zinokuhlanekezela okuthile, okuholela ekusetshenzisweni okuningi ngohlelo lokusebenza lwayo. Isibonelo, emkhakheni wezokuphepha, ilensi ye-fisheye ingangena esikhundleni samalensi amaningi ajwayelekile ukuqapha uhla olubanzi. Njengoba i-angle yokubuka ingafinyelela ku-180º noma ngaphezulu, cishe akukho i-angle efile yokuqapha. Kodwa-ke, ngenxa yokuhlanekezela kwesithombe, into kunzima ukwamukelwa yiso lomuntu, okunciphisa kakhulu ikhono lokuqapha; Esinye isibonelo sisemkhakheni wamarobhothi, amarobhothi azenzakalelayo adingekayo ukuqoqa imininingwane yezithombe ezizungezile futhi azikhombise ukuthatha izenzo ezihambisanayo.
Uma aI-Fisheye LensKuyasetshenziswa, ukusebenza kahle iqoqo kungandiswa ngezikhathi ezi-2-4, kepha ukuguquguquka kwenza isoftware ibe nzima ukukhomba. Ngakho-ke sisibona kanjani isithombe esivela ku-lens ye-fisheye? I-algorithm ihlinzekelwe ukukhomba izikhundla zezinto esithombeni. Kepha kunzima futhi ukubona ukuqashelwa kwehluzo eziyinkimbinkimbi ngenxa yobunzima be-computational yesoftware. Ngakho-ke, indlela ejwayelekile manje ukuqeda ukuhlanekezela esithombeni ngochungechunge lwezinguquko, ukuze uthole isithombe esijwayelekile bese usikhomba.
Izithombe ze-fisheye zihlelwe futhi zilungiswa
Ubudlelwano phakathi kombuthano wesithombe nenzwa kungokulandelayo:
Ubudlelwano phakathi kombuthano wesithombe nenzwa
Ekuqaleni,amalensi we-fisheyebasetshenziswe kuphela ezithombeni ngenxa yama-aesthetics abo akhethekile ngenxa yokuhlanekezela umgqomo abawakha ngesikhathi senqubo yokucabanga. Eminyakeni yamuva, ukusetshenziswa kwe-Fisheye Lens kuvame ukusetshenziswa emkhakheni we-Wide-angle imaping, ezempi, ukubhekwa, ukumbumbuluzwa, ukuqagela okunjalo nokunye. Uma kuqhathaniswa namanye amalensi, amalensi we-fisheye anezinzuzo zesisindo esikhanyayo nosayizi omncane.
