Ni ikiindorerwamo y'amaso y'ifiLensi ya Fisheye ni lensi ifite inguni nini cyane ifite imiterere ibiri y'ingenzi: uburebure bugufi bw'inyuma n'uburebure bugari bw'aho igaragara. "Lensi ya Fisheye" ni izina risanzwe.
Kugira ngo irebe neza, lensi y'imbere y'iyi lensi ni ngufi cyane kandi irabyimba yerekeza imbere y'iyi lensi mu buryo bw'ikigereranyo, busa cyane n'amaso y'ifi, bityo izina "lensi y'ifi". Abantu banayita "amashusho ya fisheye".
Ishusho ya lensi y'ijisho rya fisheye ni nini cyane, kandi ishusho ifata irimo amakuru menshi cyane, bityo ntigomba kuzunguruka cyangwa gushakisha kandi ishobora gukora mu buryo bwo kureba. Iyo lensi y'ijisho ivanze n'ibyiza byo kuba ntoya no guhisha cyane, ifite akamaro kadasanzwe mu nzego zitandukanye.
1.Ihame ry'indorerwamo y'amaso y'ifi
Iyo imboni y'ijisho ry'umuntu izenguruka kugira ngo irebe, inguni yo kureba ishobora kwaguka ikagera kuri dogere 188. Iyo imboni y'ijisho idazenguruka, inguni yo kureba neza ni dogere 25 gusa. Kimwe n'imboni y'ijisho isanzwe (imboni yo kureba dogere 30-50), imboni y'ijisho ry'umuntu nayo iba irambuye, ifite inguni nto yo kureba, ariko ishobora kubona ibintu biri kure.
Bitandukanye n'ijisho ry'umuntu, lensi iri mu jisho ry'ifi ni uruziga, bityo nubwo ishobora kubona ibintu byegeranye gusa, ifite inguni nini yo kureba (inguni yo kureba dogere 180-270), bivuze ko ishobora kubona cyane.
Ihame ryo gufata amashusho y'imboni y'amaso
Indorerwamo zisanzwe zifite imiterere igororotse zikoresha imiterere igororotse kugira ngo zigabanye uburyo bwo kugoreka.Indorerwamo z'amafiKu rundi ruhande, ubusanzwe ikoresha imiterere idashingiye ku murongo. Imiterere y'imiterere y'iyi miterere ni yo igena imiterere yayo y'inguni nini cyane kurusha iy'amabara asanzwe, ariko inatera "guhindagurika kw'imirongo" ku buryo budasubirwaho.
Ni ukuvuga ko, munsi y'agace kamwe, ingano y'amakuru ari hafi y'ishusho y'ifi ni yo nini cyane kandi imiterere yayo ni ntoya, mu gihe uko radius yiyongera, ingano y'amakuru igabanuka kandi imiterere yayo igenda yiyongera buhoro buhoro.
Guhindura imigozi ni inkota ifite ubugi bubiri: mu bushakashatsi bwa siyansi, hashyirwa imbaraga nyinshi mu kuyikosora kugira ngo haboneke imiterere y’impande zagutse cyane mu gihe hagabanywa guhindura amashusho, mu gihe mu ikoranabuhanga rya filime, guhindura imigozi bishobora guha amashusho isura nziza kandi idasanzwe.
2.Amateka ya Fisheye Lens
Amateka y'indorerwamo z'amafishi ashobora gukururwa kuva mu ntangiriro z'ikinyejana cya 20. Mu 1906, umuhanga mu bya fiziki w'Umunyamerika Robert W. Wood yatanze igitekerezo cya mbere cy'indorerwamo z'amafishi. Yakoresheje indorerwamo z'amafishi kugira ngo akore amashusho ya 180° y'ubuso bw'amazi ari munsi y'amazi. Yatekereje kwigana aho amafishi akorera maze akora indorerwamo y'amafishi ishobora gukora amashusho yo mu gice cy'isi.
Mu 1922, WN Bond yanoje "lensi ya fisheye" ya Wood. Mu myaka ya 1920, lensi za fisheye zakunze gukoreshwa mu bumenyi bw'ikirere mu kwiga imiterere y'ibicu bitewe n'inguni yabyo yo kureba, yashoboraga gufata ikirere cyose. Mu myaka ya 1940, Robin Hill yakoze lensi ya fisheye koko ayikoresha mu bucuruzi. Yanoje urumuri rw'lensi ya fisheye anagabanya umubare wa F wa sisitemu.
Mu myaka ya 1960, ubwo indorerwamo za fisheye zakorwaga ku bwinshi, indorerwamo za fisheye zakundwaga n’inzego zitandukanye maze zitangira kuba imwe mu ndorerwamo zikoreshwa cyane muri filime, siporo ikabije n’ubushakashatsi bwa siyansi.
Ijisho ry'ifi
Mu ntangiriro z'ikinyejana cya 21, gukundwa kwa kamera za digitale n'iterambere ry'ikoranabuhanga ryo gufotora byatumyeindorerwamo z'amaso y'ifizitangira kwinjira mu rwego rwo kureba neza kw'abaguzi basanzwe. Hari ubwoko bwinshi butandukanye bw'indorerwamo z'amaso ya fisheye ku isoko, zitari gusa zigira ingaruka nziza, ahubwo zinafite ubushobozi bwo kwerekana amabara menshi, zishobora guhaza ibisabwa n'abakunzi b'amafoto kugira ngo habeho ireme ry'amafoto.
3.Gukoresha lenzi y'amaso ya fisheye
Indorerwamo za Fisheye zikoreshwa cyane mu nzego nyinshi bitewe n'imiterere yazo yihariye y'amatara n'ubushobozi bwo gufata inguni zo kureba zagutse cyane.
Porogaramu z'ubuhanzi bwa filime
Gukoresha lenzi y'ijisho ry'ifi mu gufata amashusho bizatuma abari aho bumva bataye umutwe kandi bashishikajwe. Urugero, iyo umukinnyi abyutse afite indwara ikomeye yo kubura amazi kandi akaba atazi neza aho ari, lenzi y'ijisho ry'ifi ishobora kwerekana uko abantu babibona mu buryo butari bwo. Byongeye kandi, lenzi z'ijisho ry'ifi nazo ni ingenzi mu gufata amashusho y'ibice nk'amajwi y'umutekano yafashwe ndetse n'indorerwamo z'indorerwamo z'inzugi zirwanya ubujura.
Bikabijesibyambu
Ijisho rya fisheye ni ikintu cy'ingenzi kugira ngo umuntu afate imikino idasanzwe nko gusiganwa ku maguru no gusiganwa ku maguru. Rituma umufotozi abona neza umukinnyi ukina ku maguru mu gihe yibanda kuri skateboard.
Indorerwamo za fisheye zikunze gukoreshwa mu gufata amashusho y'imikino idasanzwe
Gukurikiranaaporogaramu
Mu igenzura ry'umutekano, urwego rw'impande zagutse rw'ishushoindorerwamo z'amaso y'ifiishobora gukwirakwira ahantu hanini no gukuraho ahantu hadasobanutse. Ishobora gukoreshwa mu kugenzura ahantu hanini, nko mu byumba by'ingoro, mu bubiko, aho baparika imodoka, nibindi, kugira ngo itange ubushobozi bwo kugenzura ahantu hanini no kunoza imikorere n'umutekano byo kugenzura. Urugero, kamera ya fisheye ishyizwe mu isoko ishobora gukurikirana ahantu hose hagurishirizwa hatabayeho kamera nyinshi zisanzwe.
Ikoranabuhangarubuziranenge
Indorerwamo za Fisheye zishobora gukoreshwa mu gufata amashusho cyangwa videwo by’ibidukikije, zigatanga amashusho y’ibintu nyabyo ku bijyanye n’ukuri kuri interineti no gukoresha ikoranabuhanga rya “augmented reality”. Indorerwamo za Fisheye zemerera abakora ibikubiye muri VR gufata ishusho yagutse y’isi kuri interineti, bigana icyerekezo cy’umuntu kandi bikongera uburyo bwo kwiyumvamo. Urugero, mu rwego rw’ubukerarugendo kuri interineti, indorerwamo za fisheye zishobora gufata amashusho ya panoramic, zikajyana abakoresha ahantu ha kure, kandi zigatanga uburambe bw’ingendo bushimishije.
Amafoto yo mu kirere n'amafoto y'indege zitagira abapilote
Indorerwamo za fisheye nazo zikunze kugaragara mu mafoto yo mu kirere no mu mafoto y’indege zitagira abapilote, zishobora gufata amashusho menshi kandi zigatanga amashusho meza kandi afite ingaruka nziza.
Indorerwamo za fisheye zikunze gukoreshwa mu gufata amafoto yo mu kirere no gufata amafoto y'indege zitagira abapilote
Ubushakashatsi bwa siyansi
Mu rwego rw'ubushakashatsi bwa siyansi, indorerwamo z'amaso y'ifi zikoreshwa cyane mu bushakashatsi bw'ubutaka, kwitegereza ikirere, gufata amashusho y'ubuvuzi, n'ibindi, kandi zishobora gutanga amakuru n'amakuru arambuye.
Indorerwamo z'amafibishobora gutanga ubunararibonye bwihariye bwo kureba no gukurikirana ibintu bitandukanye, kandi ni igice cy'ingenzi cy'ikoranabuhanga rigezweho ryo kureba. Hamwe n'iterambere rihoraho ry'ikoranabuhanga, ikoreshwa rya lenzi z'amaso y'ifi rizarushaho kwaguka, bikazana uburyo bworoshye n'udushya mu buzima bwacu no mu kazi kacu.
Ibitekerezo bya nyuma:
ChuangAn yakoze igishushanyo mbonera cy’ibanze cy’indorerwamo z’amaso ya fisheye, zikoreshwa cyane mu nzego zitandukanye. Niba ushishikajwe cyangwa ukeneye indorerwamo z’amaso ya fisheye, twandikire vuba bishoboka.
