Lens dzakareruka dzinogadzira zvirinani mufananidzo wemhando, vimbiso kubva kune vaongorori

Vatsvakurudzi vanogadzira algorithm yekuvandudza mhando yemifananidzo

Boka revatsvagiri paUniversity yeBritish Columbia neYunivhesiti yeSiegen vakauya necomputer yehunyanzvi hwekutora mifananidzo inokwanisa kuvandudza zvakanyanya mhando yemifananidzo yemifananidzo yakatorwa neDSLR makamera akashongedzerwa neakareruka, asina chinhu maalensi.

Vatsvakurudzi vanovimbisa zvirinani zvemhando yemhando vachishandisa malenzi akareruka, kuruboshwe ndiko kwekutanga uye kurudyi chakarongedzwa sampuro yemufananidzo.

Kutsiva yakaoma kamera lens neimwe nzira dzakareruka

Iyo lens yemakamera emazuva ano mudziyo wakaomarara kwazvo: sezvo girazi rega rega rinounza rayo zvaro mufananidzo unokanganisa uye zvinokanganisa, vagadziri vanofanirwa kuisa akawanda magirazi zvinhu, eakasiyana maumbirwo uye hukuru, nechinangwa chekudzima -mumwe nemumwe kukanganisa. . Nekuda kweizvozvo, yakanaka yemhando lens inogona kuve neanopfuura zvinhu makumi maviri, ine mhedzisiro yakanangana pamutengo wayo uye uremu.

mune bepa yakagadzirirwa musangano wakakurumbira weSIGGRAPH, boka revaongorori veCanada neGerman vanouya neimwe nzira. Panzvimbo pemalensi akaomarara ezuva ranhasi, vanodzokera kuzvinhu zvekutanga uye vanoshandisa lenzi yakapusa uye isingadhuri, sezvo yaishandiswa mumazuva ekare, vobva vatendeukira kune mamwe maalgorithms ehungwaru kugadzirisa mufananidzo wakaguma mushure mekugadziriswa. Iwo maalgorithms haasi mashiripiti, asi akaoma masvomhu uye musimboti weiyi pepa.

Anoreruka lenzi dzinogadzira zvirinani mufananidzo mhando uchishandisa maalgorithms

Nechinangwa chekutsvaga, ivo vaishandisa dhijitari yazvino SLR kamera ine chete yakasarudzika-yakagadzirwa imwechete lens zvinhu zvakaita seplano-convex kana biconvex lenses, uye achromatic doublets. Mhedzisiro yacho yaive yemhando yemhando yakafanana neiyo yekutengesa poindi-uye-kupfura kamera yemapereji anotenderedza f / 4.5, asi nekudzikisira muhunhu hweakakura maapureti e f / 2 uye kupfuura. Kunyange zvisizvo zvemalensi zvinhu zvisingatsivi lens yekumusoro-soro, kushandisa matekiniki akadaro kunogona kukonzera kurerukirwa kwekuvakwa kwema lens uye nekudaro kudzikira kwemutengo nekurema.

Kwayedzwa pane lens yekutengesa seCanon 28-105 mm, uchishandisa nzira iyi inogona kugadzirisa mufananidzo wakaguma, saka maalgorithms anogona kuve nechinangwa chekushandisa, kwete kusungirwa kune imwechete lens lens.

Vatsvakurudzi vachine nzira yakareba mberi yekuvandudza lens

Pane rimwe basa rinofanira kuitwa; parizvino, ivo vaongorori vari kugadzirisa mifananidzo ine poindi yekuparadzira mabasa (PSFs) akaenzana kune imwechete nzvimbo kudzika. Izvi zvinogona kuvandudzwa nekuita deconvolution nemaPSFs emhando dzakasiyana dzemifananidzo uye wavelengths. Kugadziridza kwakadai kunogona kuitwa uchiziva paramende yeiyo Optical system. Kune yakawanda nzvimbo yekuvandudza uye pakupedzisira isu tingave neakareruka lenzi anogadzira zvirinani mufananidzo mhando.

Kana iwe uchifarira iwo akanaka ruzivo uye iwo anotevera masvomhu, bepa rizere rinowanikwa rekuverenga.
