Imashini yerekana imashinini lens yagenewe gukoreshwa muri sisitemu yo kureba imashini, izwi kandi nka kamera yinganda. Sisitemu yo kureba imashini mubisanzwe igizwe na kamera yinganda, lens, isoko yumucyo, hamwe na software itunganya amashusho.
Bakoreshwa muguhita bakusanya, gutunganya, no gusesengura amashusho kugirango bahite basuzuma ubuziranenge bwibikorwa cyangwa gupima neza imyanya iboneye ntaho bahurira. Bakunze gukoreshwa mugupima neza-neza, guteranya byikora, kugerageza kudasenya, gutahura inenge, kugendana robot nibindi bice byinshi.
1.Ni iki ukwiye gusuzuma mugihe uhitamo imashini yerekana imashini?
Iyo uhitamoimashini yerekana imashini, ugomba gusuzuma ibintu bitandukanye kugirango ubone lens ikubereye. Ibintu bikurikira nibisanzwe:
Umwanya wo kureba (FOV) nintera yakazi (WD).
Umwanya wo kureba hamwe nintera yakazi igena uko ikintu kinini ushobora kubona nintera kuva lens kugera kukintu.
Ubwoko bwa kamera ihuye nubunini bwa sensor.
Lens wahisemo igomba guhuza kamera yawe ya kamera, kandi ishusho igoramye ya lens igomba kuba irenze cyangwa ingana na diagonal intera ya sensor.
Ikirangantego cyanduye.
Birakenewe gusobanura niba porogaramu yawe isaba kugoreka hasi, gukemura cyane, ubujyakuzimu bunini cyangwa ibinini binini bya aperture.
Ingano yikintu nubushobozi bwo gukemura.
Ninini ikintu ushaka kumenya nuburyo imyanzuro isabwa igomba kuba isobanutse, igena ingano nini yo kureba hamwe na pigiseli zingahe kamera ukeneye.
Eibidukikije.
Niba ufite ibisabwa byihariye kubidukikije, nka shitingi, itagira ivumbi cyangwa irinda amazi, ugomba guhitamo lens ishobora kuzuza ibyo bisabwa.
Ingengo yimari.
Ni ikihe giciro ushobora kugura kizagira ingaruka ku kirango cya lens na moderi wahisemo.
Icyerekezo cyimashini
2.Uburyo bwo gutondekanya ibyuma byerekana imashini
Hariho ibintu byinshi ugomba gusuzuma muguhitamo lens.Imashini yerekana icyerekezoirashobora kandi kugabanwa muburyo butandukanye ukurikije amahame atandukanye:
Ukurikije ubwoko bwuburebure bwibanze, burashobora kugabanywamo:
Intumbero ihamye (uburebure bwibanze burashizweho kandi ntibushobora guhinduka), zoom zoom (uburebure bwibanze burahinduka kandi imikorere iroroshye).
Ukurikije ubwoko bwa aperture, burashobora kugabanywamo:
Intoki za aperture intoki (aperture igomba guhindurwa nintoki), lens ya aperture yikora (lens irashobora guhita ihindura aperture ukurikije urumuri rwibidukikije).
Ukurikije ibisobanuro byerekana amashusho, birashobora kugabanywamo:
Indangururamajwi zisanzwe (zikwiranye nibisabwa muri rusange nkibikurikiranwa bisanzwe no kugenzura ubuziranenge), ibyuma bihanitse cyane (bikwiranye no gutahura neza, gufata amashusho yihuta nibindi bisabwa bifite ibisubizo bihanitse).
Ukurikije ubunini bwa sensor, irashobora kugabanywamo:
Imiterere ntoya ya sensororo (ikwiranye na sensor ntoya nka 1/4 ″, 1/3 ″, 1/2 ″, nibindi), imiterere ya sensor yo hagati (ikwiranye na sensor nini-nini nka 2/3 ″, 1 ″ , nibindi sensor), ibyuma binini byerekana imiterere (kuri 35mm yuzuye-ikadiri cyangwa sensor nini).
Ukurikije uburyo bwo gufata amashusho, birashobora kugabanywamo:
Lens yerekana amashusho ya Monochrome (irashobora gufata gusa amashusho yumukara numweru), lens yerekana amashusho (irashobora gufata amashusho yamabara).
Ukurikije ibisabwa byihariye bikora, birashobora kugabanywamo:Lens-kugoreka.
