Nabona he kugeza kuri kamera yubushyuhe?

Nibyiza, iki nikibazo cyumvikana ariko nta gisubizo cyoroshye.Hariho ibintu byinshi cyane byagira ingaruka kubisubizo, nko kwiyongera mubihe bitandukanye byikirere, ibyiyumvo bya detektori yumuriro, amashusho yerekana amashusho, urusaku rwapfuye-hamwe nubutaka bwinyuma, hamwe nubusumbane bwubushyuhe bwinyuma.Kurugero, ikibabi cyitabi kirasobanutse neza kubona kuruta amababi yo ku giti intera imwe niyo yaba ari mato cyane, kubera intego yubushyuhe butandukanye.
Intera yo gutahura nigisubizo cyo guhuza ibintu bifatika nibintu bifatika.Bifitanye isano nindorerezi yindorerezi ya psychologiya, uburambe nibindi bintu.Kugira ngo dusubize “kamera yumuriro ishobora kugera he”, tugomba kumenya icyo bivuze mbere.Kurugero, kugirango umenye intego, mugihe A yibwira ko ashobora kuyibona neza, B ntashobora.Kubwibyo, hagomba kubaho ibipimo ngenderwaho kandi bihuriweho.

Ibipimo bya Johnson
Johnson yagereranije ikibazo cyo kumenya amaso hamwe numurongo umwe ukurikije ubushakashatsi.Umurongo umwe ni intera yagabanijwe hejuru yumucyo ugereranije numurongo wijimye kumupaka wubushishozi bwindorerezi.Umurongo umwe niwo uhwanye na pigiseli ebyiri.Ubushakashatsi bwinshi bwerekanye ko bishoboka kumenya ubushobozi bwo kumenya intego ya sisitemu ya infragre yumuriro wa sisitemu ukoresheje imirongo ibiri utitaye kumiterere yintego nubusembwa bwibishusho.

Ishusho ya buri ntego mu ndege yibanze ifata pigiseli nkeya, ishobora kubarwa uhereye ku bunini, intera iri hagati yintego na imager yumuriro, hamwe numwanya wo kureba (IFOV).Ikigereranyo cyubunini bwintego (d) nintera (L) bita inguni ya aperture.Irashobora kugabanwa na IFOV kugirango ibone umubare wa pigiseli ifitwe nishusho, ni, n = (D / L) / IFOV = (DF) / (LD).Birashobora kugaragara ko uko uburebure bwibanze, niko ingingo zingenzi zifatwa nishusho yagenewe.Ukurikije ibipimo bya Johnson, intera yo kumenya ni kure.Ku rundi ruhande, uko uburebure burebure bwibanze, ntoya inguni, kandi igiciro cyaba kinini.

Turashobora kubara intera ishusho yubushyuhe ishobora kubona hashingiwe kumyanzuro mike ukurikije Ibipimo bya Johnson:

Kumenya - ikintu kirahari: 2 + 1 / -0.5 pigiseli
Kumenyekana - ubwoko bwikintu gishobora gutahurwa, umuntu nu modoka: 8 + 1.6 / -0.4 pigiseli
Kumenyekanisha - ikintu runaka gishobora gutahurwa, umugore numugabo, imodoka yihariye: 12.8 + 3.2 / -2.8 pigiseli
Ibi bipimo bitanga 50% bishoboka ko indorerezi ivangura ikintu kurwego rwagenwe.
