1.Iyini ilensi yokuhlanekezela ephansi?

Kuyini ukuhlanekezela?Ukuhlanekezela igama ikakhulukazi elisetshenziselwa izithombe zezithombe.Kubhekiselwa entweni yenqubo yokuthatha izithombe ukuthi ngenxa yemikhawulo ekwakhiweni nasekukhiqizeni ilensi noma ikhamera, umumo nosayizi wezinto ezisesithombeni zihlukile ezintweni zangempela.

Inkinga yokuhlanekezela ithinta kakhulu izinga nokubukeka nokuzwakala kwezithombe.Ukuze kuxazululwe le nkinga, abantu baqala ukuthuthukisa nokusebenzisa ama-lens aphansi.

Yini ai-lens ephansi yokuhlanekezela?Ilensi yokuhlanekezela okuphansi iyilensi ekhethekile yokuthwebula izithombe ne-optical imaging.Le lens inganciphisa ngempumelelo noma iqede imiphumela yokuhlanekezela ngokusebenzisa i-optical design enembile kanye nezinqubo zokukhiqiza, kanye nokusetshenziswa kwezinto ezikhethekile zengilazi nezinhlanganisela zamalensi.

Ngokusebenzisa amalensi ahlanekezela kancane, abathwebuli bezithombe nabathwebuli bevidiyo bangathola izithombe ezingokoqobo, ezinembile nezemvelo lapho bethwebula, ngokuvamile okuhambisana nokuma nosayizi wezinto zangempela.

Umdwebo wokuhlanekezela amalensi

2.Yiziphi izinzuzo zamalensi ahlanekezelayo aphansi?

Ngaphezu kokunciphisa izinkinga zokuhlanekezela, amalensi angahlanekezeli kancane futhi anezinzuzo ezithile eziwenza asetshenziswe kabanzi emikhakheni eminingi yohlelo lokusebenza, njengokuthwebula izithombe zezakhiwo, ukuthwebula izithombe komkhiqizo, ucwaningo lwesayensi, njll. Ake sibhekisise:

Ilensi yokuhlanekezela ephansi inikeza ukuthwebula kweqiniso, okunembile

Amalensi ahlanekezela kancane ngokuvamile ahlinzeka ngesithombe esinembe kakhudlwana.Ngokunciphisa ukuhlanekezela, umumo nezilinganiso zezinto ezisesithombeni zigcinwa zinembile, zinikeza izithombe ezinemininingwane ecacile nemibala eyiqiniso.

Ngezimo zohlelo lokusebenza ezidinga izithombe zekhwalithi ephezulu, kubaluleke kakhulu ukuzisebenzisaama-lens aphansi, njengokuthatha izithombe, ukuhlolwa kwezimboni, ukuthwebula izithombe zezokwelapha, njll.

Ilensi yokuhlanekezela okuphansi ithuthukisa ukunemba kokulinganisa

Ezinkambini ezifana nokulinganisa nokuhlola, ukuhlanekezela kungaholela emaphutheni, ngaleyo ndlela kunciphise ukunemba kokulinganisa.Ukusetshenziswa kwamalensi ahlanekezela kancane kunganciphisa kakhulu leli phutha, kuthuthukise ukunemba kokulinganisa, futhi kuqinisekise ukunemba nokuthembeka kwemiphumela yokulinganisa.

Ilensi yokuhlanekezela ephansi

Ilensi yokuhlanekezela ephansi ithuthukisa ukucutshungulwa kwesithombe

Embonini yekhompyutha nezinhlelo zokusebenza zokucubungula izithombe, ukuhlanekezela kuzodala ukuphazamiseka kuma-algorithms nokucutshungulwa okulandelayo.Iyafakaama-lens aphansiinganciphisa ubunkimbinkimbi bokucubungula futhi yenze kube lula ukucutshungulwa kwesithombe okulandelayo.

Phansi ama-lens ahlanekezela athuthukisa ulwazi lomsebenzisi

Amalensi ahlanekezela aphansi awasetshenziswa nje kuphela ezinkambini zobungcweti, kodwa futhi ahlinzeka abasebenzisi abajwayelekile ngomuzwa ongcono wokudubula.Ngokunciphisa ukuhlanekezela, izithombe zenziwa zibe ngokoqobo futhi zemvelo, okuvumela abantu ukuthi baqophe kangcono futhi bakhumbule izikhathi ezibalulekile.

Ngaphezu kwalokho, ama-lens ahlanekezela kancane anganciphisa ukunwebeka kwesithombe nokuguqulwa, okuvumela izibukeli ukuba zibone ngokunembile umumo nosayizi wezinto eziqondiwe.Lokhu kubaluleke kakhulu kochwepheshe emikhakheni efana nocwaningo lwesayensi nokwakhiwa kwezimboni.

Ilensi yokuhlanekezela ephansi iqinisekisa ikhwalithi yokuqagela

Amalensi okuhlanekezela aphansizisetshenziswa kakhulu kumishini yokuqagela, engagcina ikhwalithi yokuqagela yesithombe futhi yenze isithombe sokuqagela sicace futhi sibhebhe.Lokhu kuzuzisa kakhulu ezindaweni ezifana namagumbi enkomfa namatiyetha asekhaya adinga ukuboniswa kwesikrini esikhulu.
