Ni ubuhe bwoko bwa Fisheye nubwoko bwingaruka za Fisheye

Intebe ya fisheye ni lens nini cyane, kandi izwi nka lens panoramic.Mubisanzwe bifatwa ko lens ifite uburebure bwa 16mm cyangwa uburebure bugufi bwerekanwe ni lens ya fisheye, ariko mubuhanga bwubuhanga, lens ifite inguni ireba dogere zirenga 140 hamwe hamwe bita fisheye lens.Mu myitozo, hari na lens ifite inguni zo kureba zirenga cyangwa zigera kuri dogere 270.Intebe ya fisheye nitsinda rirwanya amaterefone hamwe no kugoreka ingunguru nyinshi.Intebe yimbere yiyi lens irasa imbere, kandi imiterere isa nijisho ryamafi, niyo mpamvu izina "lens fisheye", kandi ingaruka zayo zisa niz'amafi yitegereza ibintu hejuru y'amazi.

Lensye lens yishingikiriza muburyo bwogukora uburyo bwinshi bwo kugoreka ingunguru kugirango ibone inguni nini yo kureba.Kubwibyo, usibye ikintu kiri hagati yishusho, ibindi bice bigomba kuba imirongo igororotse bifite ibyo bigoretse, biganisha kubibuza byinshi kubishyira mu bikorwa.Kurugero, murwego rwumutekano, lens ya fisheye irashobora gusimbuza lens nyinshi zisanzwe kugirango ikurikirane intera nini.Kubera ko impande zo kureba zishobora kugera kuri 180º cyangwa zirenga, nta mpande zapfuye zo gukurikirana.Ariko, kubera kugoreka ishusho, ikintu kiragoye kumenyekana nijisho ryumuntu, bigabanya cyane ubushobozi bwo gukurikirana;Urundi rugero ni mubijyanye na robo, robot zikoresha zisabwa gukusanya amakuru yishusho yerekana amashusho akikije no kubamenya gukora ibikorwa bijyanye.Niba lens ya fisheye ikoreshwa, gukusanya neza birashobora kwiyongera inshuro 2-4, ariko aberration ituma software igorana kuyimenya.Nigute dushobora kumenya ishusho kuva lens ya fisheye?Algorithm itangwa kugirango umenye imyanya yibintu mumashusho.Ariko biragoye kandi kumenya kumenyekanisha ibishushanyo bigoye bitewe no kubara kwa software.Kubwibyo, uburyo busanzwe ubu ni ugukuraho kugoreka kwishusho ukoresheje urukurikirane rwimpinduka, kugirango ubone ishusho isanzwe hanyuma uyimenye.

Isano iri hagati yumuzingi wamashusho na sensor nuburyo bukurikira:

Ubusanzwe, lens ya fisheye yakoreshwaga gusa mu gufotora kubera ubwiza bwihariye bwabo kubera kugoreka ingunguru barema mugihe cyo gufata amashusho.Mu myaka yashize, ikoreshwa rya lens ya fisheye ryakunze gukoreshwa mubijyanye no kwerekana amashusho yagutse, igisirikare, kugenzura, kwigana panoramic, projection ya spherical nibindi.Ugereranije nizindi lens, lens ya fisheye ifite ibyiza byuburemere bworoshye nubunini buto.
