Ingaba ikhamera eshushu inokubona kude kangakanani?

 

Ukuqonda ukuba kude kangakanani aikhamera eshushu(okanyeikhamera ye-infrared) uyabona, okokuqala kufuneka wazi ukuba inkulu kangakanani into ofuna ukuyibona.

Ngaphandle koko, uthini umgangatho "wokubona" ​​owuchazayo ngokuchanekileyo?

Ngokuqhelekileyo, "ukubona" ​​kuya kwahlula ngamanqanaba amaninzi:

1. Umgama omkhulu wethiyori: nje ukuba kukho ipixel enye kwi umfanekiso we-thermal isikrini ukubonakalisa into, kodwa kulo mzekelo akuyi kubakho umlinganiselo ochanekileyo wokushisa

2. Umgama womlinganiselo weqondo lobushushu: xa into ekujoliswe kuyo ikwazi ukulinganisa iqondo lobushushu elichanekileyo, ifuna ngokubanzi ubuncinci iipikseli ezi-3 ze-detector zibonakaliswe kwisixhobo, ngoko ke umgama womlinganiselo wobushushu okwithiyori lixabiso into enokuthi iphoswe 3. pixelson ikhamera yomfanekiso we-thermal.

3. Uqwalaselo kuphela, akukho umlinganiselo wobushushu, kodwa unokuchongwa, ke oku kufuna indlela ebizwa ngokuba yi-Johnson Criterion.

Lo mgaqo uquka:

(1) Ulwandlalo oluntsonkothileyo luyabonakala

(2) iimilo ziyabonakala

(3) iinkcukacha ziyabonakala

Owona mgama womfanekiso = inani leepixels ezithe nkqo × ubungakanani ekujoliswe kuko (kwiimitha) × 1000

Indawo yokujonga ngokuthe nkqo × 17.45

or

Inani leepikseli ezithe tye × ubungakanani obujoliswe kuko (ngeemitha) × 1000

Indawo yokujonga ethe tye × 17.45
