Nigute wahitamo lens iburyo kuri kamera yinganda?

Kamera yinganda nimiti yingenzi muri sisitemu yimashini. Imikorere yabo yingenzi ni uguhindura ibimenyetso bya optique mubikorwa byamashanyarazi kuri kamera ntoya yinganda.

Muri sisitemu ya imashini, lens ya kamera yinganda ihwanye nijisho ryumuntu, kandi imikorere yingenzi nukwibanda ku ntego ya optique kumurongo wamafoto ya sensor (kamera yinganda).

Ibisobanuro byose byamashusho byatunganijwe na sisitemu yo kureba birashobora kuboneka kuri lens ya kamera yinganda. Ubwiza bwaInganda za Kamerabizagira ingaruka kuri rusange imikorere ya sisitemu.

Nubwo ibikoresho byo gutekereza, Lensri ya Kamera isanzwe ikora sisitemu yuzuye yo kugura amashanyarazi, kamera, nibindi rero, guhitamo inzira ya kamera yinganda bigengwa nibisabwa muri rusange. Mubisanzwe, irashobora gusesengurwa kandi isuzumwa mubice bikurikira:

1.Uburebure bwamabuye na zoom lens cyangwa ntabwo

Biroroshye kwemeza niba lens yinganda zikeneye lens zoom cyangwa lens ihamye. Icya mbere, birakenewe kumenya niba uburebure bwakazi bwa kamera yinganda bubanda. Mugihe cyo gutekereza, niba kumenyera bigomba guhinduka, lens zoom igomba gukoreshwa, bitabaye ibyo, lens ihamye ihagije irahagije.

Kubyerekeye uburebure bwakazi bwaInganda Inganda, itsinda rigaragara rigaragara ni rikunze kugaragara, kandi hariho kandi porogaramu mu zindi matsinda. Ingero zinyongera zisabwa? Ni monochromatic cyangwa umucyo wa polychromatic? Ese ingaruka zumucyo wazimiye zirinda neza? Birakenewe kumvikana gupima ibibazo byavuzwe haruguru mbere yo kumenya uburebure bwakazi bwa lens.

2.Icyambere gitangwa kubisabwa bidasanzwe

Ukurikije porogaramu nyirizina, hashobora kubaho ibisabwa byihariye. Ibisabwa bidasanzwe bigomba kwemezwa mbere, kurugero, niba hari imikorere yo gupima, niba ishusho yibanze ari nini cyane, nibindi. Ubujyakuzimu bwibanze akenshi ntabwo bufatana uburemere, ariko sisitemu yo gutunganya ibitekerezo kuzirikana.

3.Intera ikora no kwibanda

Intera yakazi hamwe nuburebure busanzwe busuzumwa hamwe. Igitekerezo rusange nukumenya bwa mbere uburyo bwo gukemura, hanyuma usobanure gukuza hamwe nubunini bwa CCD Pixel, hanyuma wumve intera ishoboka-ishusho ishoboka, kugirango ugereranye inzitizi yuburebure bwa Inganda za Kamera.

Kubwibyo, uburebure bwibanze bwa kamera yinganda bufitanye isano nintera ya kamera yinganda zinganda zinganda hamwe nicyemezo cya kamera (kimwe ningano ya CCD pigiseli).

4.Ingano yishusho hamwe nuburyo bwiza

Ingano y'ishusho yaInganda za Kameragutoranywa bigomba guhuzwa nubunini bwamafoto ya kamera yinganda, nihame rya "binini kugirango dukurikire, ni ukuvuga ubuso buto bwa kamera budashobora kurenza urugero bwerekanwe na lens, ubundi Imiterere yimiterere yimiterere yuburyo ntishobora kwizerwa.

Ibisabwa kugirango ubone ubuziranenge biterwa na MTF no kugoreka. Mugupima ibipimo, kugoreka bigomba kwitabwaho neza.

5.Aperture na lens

Inzu ya kamera yinganda igira ingaruka cyane cyane hejuru yubuso bwamashusho, ariko mubyerekezo byanyuma bigenwa nibintu byinshi nka aperture, umwanya wa kamera, umwanya wa kamera, etc. Kubwibyo, kugirango Shaka amashusho asabwa, intambwe nyinshi zo guhinduka zirakenewe.

Umusozi wa kamera yinganda bivuga umurongo ushyireho hagati ya lens na kamera, kandi byombi bigomba guhura. Imwe muribiri ntabwo zihuye, gusimburwa bigomba gusuzumwa.

6.Igiciro n'ikoranabuhanga

Niba nyuma yo gutekereza cyane kubintu byavuzwe haruguru, hari ibisubizo byinshi byujuje ibisabwa, urashobora gusuzuma ikiguzi cyuzuye nubuhanga bwa tekinike, kandi ubashyire imbere.

PS: Urugero rwa Lens Guhitamo

Hasi dutanga urugero rwuburyo bwo guhitamo lens kuri kamera yinganda. Kurugero, sisitemu ya Vision Yera Kumenya igiceri igomba kuba ifite ibikoresho hamwe naInganda za Kamera. Inzitizi zizwi ni: Kamera yinganda CCD ni 2/3 santimetero, ingano ya pigiseli ni 4.65μm, intera ya sisitemu irarenze 200mm Inkomoko yoroheje.

Isesengura ryibanze kugirango uhitemo lens ni izi zikurikira:

(3) Intera ikora no kwibandaho:

Gukusanya amashusho: m = 4.65 / (0.05 x 1000) = 0.093

Uburebure bwibanze: F = l * m / (m + 1) = 200 * 0.093 / 1.093 = 17mm

Niba intera ifatika isabwa kurenza 200mm, uburebure bwibanze bwa lens yatoranijwe igomba kurenza 17mm.

(4) Ingano yishusho ya lens yatoranijwe ntigomba kuba nto kurenza imiterere ya CCD, ni ukuvuga byibuze 2/3 santimetero.

(5) Lens irasabwa kuba C-umusozi kugirango ikoreshwe na kamera yinganda. Nta kintu gisabwa kuri aperture muriki gihe.

Binyuze mu gusesengura no kubara ibintu byavuzwe haruguru, turashobora kubona urucacagu rwambere rwa kamera rwinganda: Uburebure bwibanze, bwibanze, C-Long, bihuye nibura 2/3-santimetero ingano ya pigiseli, hamwe no kugoreka bito. Ukurikije ibyo bisabwa, ibindi gutoranya birashobora gukorwa. Niba lens nyinshi zishobora kuzuza ibi bisabwa, birasabwa kurushaho guhitamo no guhitamo lens nziza.

Ibitekerezo byanyuma:

Chuangan yakoze igishushanyo mbonera no gukoraLensrial Lens, zikoreshwa mubice byose byinganda za porogaramu zinganda. Niba ushimishijwe cyangwa ukeneye inzira yinganda, nyamuneka twandikire vuba bishoboka.
