Kuyiniilensi yeso lenhlanziIlensi yeFisheye ilensi ebanzi kakhulu ene-engeli ebanzi kakhulu enezici ezimbili eziyinhloko: ubude obufushane bokugxila kanye nensimu ebanzi yokubuka. Igama elithi “ilensi yeFisheye” yigama layo elivamile.
Ukuze kukhuliswe i-engeli yokubuka yelensi, ilensi yangaphambili yale lensi imfushane kakhulu ngobubanzi futhi iqhuma ibheke phambili kwelensi ngesimo esifana kakhulu namehlo enhlanzi, yingakho igama layo libizwa ngokuthi “ilensi yefisheye”. Abantu babiza nezithombe ezithathwe yiyo ngokuthi “izithombe zefisheye”.
Insimu yokubuka ilensi ye-fisheye inkulu kakhulu, futhi uhlaka lwesithombe olusithwebulayo luqukethe ulwazi olucebile kakhulu, ngakho-ke aludingi ukujika noma ukuskena futhi lungasebenza ngendlela yokubuka. Uma ihlanganiswe nezinzuzo zobukhulu obuncane kanye nokucasha okuqinile, ilensi ye-fisheye inenani eliyingqayizivele lokusebenza emikhakheni eyahlukahlukene.
1.Isimiso se-lens ye-fisheye
Uma inhlamvu yeso yomuntu ijikeleza ukuze ibone, i-engeli yokubuka ingandiswa ibe ngama-degree angu-188. Uma inhlamvu yeso ingajikelezi, i-engeli yokubuka esebenzayo ingama-degree angu-25 kuphela. Njengelensi yekhamera evamile (i-engeli yokubuka ama-degree angu-30-50), ilensi yeso lomuntu nayo igobile, ine-engeli yokubuka encane, kodwa ingabona izinto ezikude.
Ngokungafani neso lomuntu, ilensi eliso lenhlanzi iyindilinga, ngakho-ke yize ingabona izinto eziseduze kuphela, ine-engeli yokubuka enkulu (i-engeli yokubuka engu-180-270 degrees), okusho ukuthi ingabona kabanzi.
Isimiso sokuthwebula izithombe ngelensi ye-fisheye
Amalensi avamile ane-engeli ebanzi asebenzisa umklamo oqondile ukuze anciphise ukuphambuka.Amalensi e-FisheyeNgakolunye uhlangothi, ngokuvamile zisebenzisa isakhiwo esingesiwo umugqa. Izakhiwo zomzimba zalesi sakhiwo zinquma izici zaso ezibanzi kakhulu kunezamalensi avamile, kodwa futhi ziholela "ekuphazamisekeni kwemiphongolo" okungenakugwenywa.
Okusho ukuthi, ngaphansi kwendawo efanayo, inani lolwazi oluseduze nesikhungo sesithombe se-fisheye likhulu kunawo wonke kanti ukuguquguquka kuncane kakhulu, kuyilapho njengoba i-radius ikhula, inani lolwazi liyancipha futhi ukuguquguquka kuyanda kancane kancane.
Ukuhlanekezela kwebhareli kuyinkemba esika nhlangothi zombili: ocwaningweni lwesayensi, kwenziwa umzamo omkhulu ekulungiseni ukuze kutholakale amasimu okubuka ane-engeli ebanzi kakhulu ngenkathi kunciphisa ukuhlanekezela kwesithombe, kanti emikhakheni efana nobuciko bamafilimu, ukuhlanekezela kwebhareli kunganikeza izithombe ukubukeka okunesibindi nokuyingqayizivele.
2.Umlando Welensi Ye-Fisheye
Umlando wamalensi e-fisheye ungalandelelwa emuva ekuqaleni kwekhulu lama-20. Ngo-1906, isazi sefiziksi saseMelika uRobert W. Wood saqala ukuhlongoza umqondo ngelensi ye-fisheye. Wasebenzisa ama-fisheye ukwakha izithombe ezingama-180° zobuso bamanzi kusukela phansi kwamanzi. Wacabanga ukulingisa indawo yokusebenza yama-fisheye futhi wadala ilensi ye-fisheye engakha izithombe ze-hemispherical.
Ngo-1922, i-WN Bond yathuthukisa “ilensi yefisheye” kaWood. Ngawo-1920, amalensi efisheye ayevame ukusetshenziswa kwi-meteorology ukutadisha ukwakheka kwamafu ngenxa ye-engeli yawo yokubuka ebanzi, eyayingabamba isibhakabhaka sonke. Ngawo-1940, uRobin Hill wadala ngempela ilensi yefisheye futhi wayisebenzisela izinjongo zezentengiselwano. Wathuthukisa ukukhanya okulinganiselwe kwelensi yefisheye futhi wanciphisa inombolo ye-F yesistimu.
Ngawo-1960, ngokukhiqizwa ngobuningi kwamalensi e-fisheye, amalensi e-fisheye athandwa yimikhakha eyahlukahlukene futhi aqala ukuba ngelinye lamalensi ajwayelekile kuma-movie, ezemidlalo eziyingozi kanye nocwaningo lwesayensi.
Amalensi e-fisheye
Ekuqaleni kwekhulu lama-21, ukuthandwa kwamakhamera edijithali kanye nokuthuthuka kobuchwepheshe bezithombe kwenzaamalensi e-fisheyebaqala ukungena emkhakheni wokubona kwabathengi abavamile. Kunezinhlobo eziningi ezahlukene zamalensi e-fisheye emakethe, angabi nemiphumela ebanzi kuphela, kodwa futhi anencazelo ephezulu kanye nokukhiqizwa kombala, okungahlangabezana nezidingo zabathandi bezithombe zekhwalithi yesithombe.
3.Ukusetshenziswa kwelensi ye-fisheye
Amalensi e-Fisheye asetshenziswa kabanzi emikhakheni eminingi ngenxa yokwakheka kwawo okuhlukile kokukhanya kanye nekhono lokubamba ama-engeli okubuka abanzi kakhulu.
Izinhlelo zokusebenza zobuciko befilimu
Ukusebenzisa ilensi ye-fisheye lapho uthwebula isigcawu kuzokwenza izethameli zizizwe zilahlekile futhi zigxile. Isibonelo, lapho umlingiswa evuka ene-hangover enzima futhi engaqiniseki ukuthi ukuphi, ilensi ye-fisheye ingaveza umbono womuntu wokuqala ophambene ezilalelini. Ngaphezu kwalokho, amalensi e-fisheye nawo abalulekile ekuqopheni izigcawu ezifana nokuqoshwa kokuphepha okulingisiwe kanye nokubonwa kweminyango yokulwa nokwebiwa okulingisiwe.
Okudlulele kakhulusamachweba
Ilensi ye-fisheye iyinto ebalulekile ekuthwebuleni imidlalo eyingozi njengokugibela i-skateboard kanye ne-parkour. Ivumela umthwebuli wezithombe ukuthi abone ngokugcwele umskeyitha ngenkathi egxile kuskateboard.
Amalensi e-Fisheye avame ukusetshenziselwa ukudubula imidlalo eyingozi kakhulu
Ukuqaphaaizicelo
Ekuqapheni ukuphepha, umbono wensimu ebanzi ye-amalensi e-fisheyeingamboza indawo ebanzi futhi isuse ezinye izindawo ezingaboni. Zingasetshenziswa ukuqapha izindawo ezinkulu, njengemahholo, izindawo zokugcina impahla, izindawo zokupaka, njll., ukuhlinzeka ngamakhono okuqapha okubanzi nokuthuthukisa ukusebenza kahle kokuqapha nokuphepha. Isibonelo, ikhamera ye-fisheye efakwe enxanxatheleni yezitolo ingaqapha yonke indawo yokuthenga ngaphandle kokuhlanganiswa kwamakhamera amaningi ajwayelekile.
Okubonakalayorubulungiswa
Amalensi e-Fisheye angasetshenziswa ukuthwebula izithombe noma amavidiyo e-panoramic endawo, enikeza izigcawu zokuqukethwe ezingokoqobo kakhulu ze-virtual reality kanye nobuchwepheshe be-augmented reality. Amalensi e-Fisheye avumela abadali bokuqukethwe be-VR ukuthi bathwebule umbono obanzi womhlaba we-virtual, belingisa umbono wemvelo womuntu futhi bathuthukise umuzwa wokungena. Isibonelo, emkhakheni wezokuvakasha kwe-virtual, amalensi e-fisheye angathwebula izigcawu ze-panoramic, ayise abasebenzisi ezindaweni ezikude, futhi anikeze ulwazi lokuhamba olujulile.
Izithombe zasemoyeni kanye nezithombe ze-drone
Amalensi e-Fisheye nawo avamile ezithombeni zasemoyeni kanye nasezithombeni ze-drone, ezingathwebula izigcawu eziningi futhi zinikeze izithombe zokuhlobisa nezithinta kakhulu.
Amalensi e-Fisheye avame ukusetshenziselwa ukuthwebula izithombe zasemoyeni kanye nokuthwebula izithombe ze-drone
Ucwaningo lwesayensi
Emkhakheni wocwaningo lwesayensi, amalensi e-fisheye asetshenziswa kabanzi ekuhloleni i-geological, ukubuka izinkanyezi, ukuthwebula izithombe zezokwelapha, njll., futhi anganikeza idatha nolwazi oluphelele kakhulu.
Amalensi e-Fisheyeinganikeza isipiliyoni esiyingqayizivele sokubona kanye nobubanzi obubanzi bokuqapha, futhi iyingxenye ebalulekile yobuchwepheshe besimanje bokubona. Ngokuthuthuka okuqhubekayo kobuchwepheshe, ukusetshenziswa kwamalensi e-fisheye kuzoba kukhulu kakhulu, kulethe ukulula kanye nokusungula izinto ezintsha empilweni yethu nasemsebenzini.
Imicabango Yokugcina:
UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kwamalensi e-fisheye, asetshenziswa kabanzi emikhakheni eyahlukene. Uma unesithakazelo noma unesidingo samalensi e-fisheye, sicela usithinte ngokushesha okukhulu.
