Leyo khamera eshisayo ingabona kude kangakanani?

 

Ukuze uqonde kude kangakanani aikhamera eshisayo(nomaikhamera ye-infrared) ungabona, okokuqala udinga ukwazi ukuthi into ofuna ukuyibona inkulu kangakanani.

Ngaphandle kwalokho, liyini izinga "lokubona" ​​olichazayo kahle?

Ngokuvamile, "ukubona" ​​kuzohlukana kube amazinga amaningana:

1. Ibanga letiyori eliphakeme kakhulu: inqobo nje uma kunephikseli eyodwa ku- isithombe esishisayo isikrini ukuze sibonise into, kodwa kulokhu ngeke kube nesilinganiso esinembile sokushisa

2. Ibanga lokulinganisa izinga lokushisa okucatshangelwayo: uma into eqondiwe ukuze ikwazi ukukala izinga lokushisa elinembile, ngokuvamile idinga okungenani amaphikseli angu-3 omtshina aboniswa kudivayisi, ngakho-ke ibanga lokulinganisa izinga lokushisa elingokomqondo liyinani into engakwazi ukuliphonsa 3. amaphikselion ikhamera yesithombe esishisayo.

3. Ukubuka kuphela, akukho silinganiso sokushisa, kodwa okubonakalayo, khona-ke lokhu kudinga indlela ebizwa ngokuthi i-Johnson Criterion.

Lo mbandela ohlanganisa:

(1) Izinhlaka ezingaqondakali ziyabonakala

(2) amajamo ayabonakala

(3) imininingwane iyabonakala

Ibanga eliphezulu lokucabanga = inani lamaphikseli aqondile × usayizi oqondiwe (ngamamitha) × 1000

Inkambu yokubuka eqondile × 17.45

or

Inani lamaphikseli avundlile × usayizi oqondiwe (ngamamitha) × 1000

Indawo yokubuka evundlile × 17.45
