Yaya nisa da kyamarar zafi za ta iya gani?

 

Don fahimtar yadda nisa akyamarar thermal(koinfrared kamara) iya gani, da farko kuna buƙatar sanin girman girman abin da kuke son gani.

Bayan haka, menene ma'aunin "ganin" da kuka ayyana daidai?

Gabaɗaya magana, "ganin" zai raba zuwa matakai da yawa:

1. Matsakaicin nisa na ka'idar: muddin akwai pixel ɗaya akan thermal hoto allo don nuna abu, amma a wannan yanayin ba za a sami ma'aunin zafin jiki daidai ba

2. Nisa na auna zafin ka'ida: lokacin da abin da aka yi niyya ya sami damar auna madaidaicin zafin jiki, gabaɗaya yana buƙatar aƙalla pixels 3 na ganowa akan na'urar, don haka nisan auna zafin ka'idar shine adadin da abun zai iya jefa 3. pixelson kyamarar hoto na thermal.

3. Dubawa kawai, babu ma'aunin zafin jiki, amma ana iya ganewa, to wannan yana buƙatar hanyar da ake kira Johnson Criterion.

Wannan ma'auni ya haɗa da:

(1) ana iya bayyana shaci-fadi

(2) siffofi ana iya gane su

(3) cikakkun bayanai suna iya ganewa

Matsakaicin nisa na hoto = adadin pixels tsaye × girman manufa (a cikin mita) × 1000

Filin kallo na tsaye × 17.45

Yawan pixels a kwance × girman manufa (a cikin mita) × 1000
