Chii chinonzi Fisheye Lens uye Mhando dzeFisheye Effects

A fisheye lenziIyo yakanyanyisa yakakura-ekona lens, inozivikanwawo sepanoramic lens. Zvinowanzo fungwa kuti lenzi ine kureba kwe16mm kana kupfupika kwefocal kureba ndeye fisheye lens, asi muinjiniya, lenzi ine yekuona kona yeanodarika 140 madhigirii akaungana anodaidzwa kunzi fisheye lens. Mukuita, kunewo malenzi ane makona ekuona anodarika kana kutosvika 270 degrees. A fisheye lens iboka rechiedza rinopikisa telephoto rine zvakawanda zvekukanganiswa kwembiru. Iyo lenzi yekumberi yelenzi iyi inobuditsa kumberi, uye chimiro chakafanana neziso rehove, nekudaro zita rekuti "fisheye lens", uye maitiro ayo ekuona akafanana neaya ehove inoona zvinhu pamusoro pemvura.

Iyo fisheye lenzi

Iyo fisheye lens inotsamira pakuunza zvekugadzira huwandu hukuru hwekukanganiswa kwembiya kuti uwane hombe yekuona kona. Naizvozvo, kunze kwechinhu chiri pakati pechifananidzo, zvimwe zvikamu zvinofanirwa kuve mitsara yakatwasuka zvine kumwe kukanganisa, Izvo zvinotungamira kune zvakawanda zvinorambidzwa pakushandiswa kwayo. Semuenzaniso, mumunda wekuchengetedza, lenzi yehove inogona kutsiva akawanda akajairwa lenzi kutarisa akasiyana. Sezvo kona yekuona inogona kusvika 180º kana kupfuura, panenge pasina kona yakafa yekutarisa. Zvisinei, nekuda kwekukanganiswa kwechifananidzo, chinhu chacho chakaoma kuonekwa neziso remunhu, izvo zvinoderedza zvakanyanya kukwanisa kutarisa; Mumwe muenzaniso uri mumunda wemarobhoti, otomatiki marobhoti anodiwa kuunganidza ruzivo rwemifananidzo yezviitiko zvakatenderedza uye kuvazivisa kuti vatore zviito zvinoenderana.

Kana afisheye lenziinoshandiswa, kugona kwekuunganidza kunogona kuwedzerwa ne 2-4 nguva, asi kukanganisa kunoita kuti software iome kuziva. Saka tinoziva sei mufananidzo kubva kune fisheye lens? Algorithm inopiwa kuratidza nzvimbo dzezvinhu zviri mumufananidzo. Asi zvakare zvakaoma kuziva kucherechedzwa kweakaomesesa magiraidhi nekuda kwekuomeserwa kwesoftware. Naizvozvo, nzira yakajairika ikozvino ndeyekubvisa kukanganisa mumufananidzo kuburikidza neakatevedzana shanduko, kuitira kuti uwane yakajairika mufananidzo uye wozoizivisa.

Pakutanga,fisheye lenzivaingoshandiswa mukutora mifananidzo nekuda kweaesthetics yavo yakakosha nekuda kwekukanganiswa kwembiru kwavanogadzira panguva yekufungidzira. Mumakore achangopfuura, kushandiswa kwefisheye lens kwave kuchiwanzo shandiswa mumunda wemifananidzo yakafara-ekona, mauto, kutarisa, panoramic simulation, spherical fungidziro uye zvichingodaro. Kuenzaniswa nemamwe malenzi, iyo fisheye lens ine zvakanakira uremu huremu uye saizi diki.
