Pehea ka lōʻihi e ʻike ai kēlā pahupaʻikiʻi wela?

 

E hoomaopopo i ka mamao apahupaʻi wela wela(a i ʻolekamera infrared) hiki ke ʻike, pono ʻoe e ʻike i ka nui o ka mea āu e makemake ai e ʻike.

Ma waho aʻe, he aha ke ʻano o ka "ʻike" āu e wehewehe pono ai?

Ma ka ʻōlelo maʻamau, e māhele ʻia ka "ʻike" i kekahi mau pae:

1. Theoretical mamao loa: i ka lōʻihi o hoʻokahi pika ma ka kiʻi wela pale e hōʻike i ka mea, akā i kēia hihia, ʻaʻohe ana wela kūpono

2. ʻO ka mamao ana o ke ana wela: i ka wā e hiki ai ke ana i ka mahana pono o ka mea i manaʻo ʻia, pono ia ma ka liʻiliʻi he 3 pixels o ka detector e hōʻike ʻia ma ka hāmeʻa, no laila ʻo ka mamao o ke ana wela ka nui o ka mea hiki ke hoʻolei 3 nā pikaon pahupaʻi kiʻi wela.

3. ʻO ka nānā wale ʻana, ʻaʻohe ana wela, akā hiki ke ʻike ʻia, a laila pono kēia i kahi ala i kapa ʻia ʻo Johnson Criterion.

ʻO kēia criterion me:

(1) ʻike ʻia nā outline pohihihi

(2) ʻike ʻia nā ʻano

(3) ʻike ʻia nā kikoʻī

Ka mamao kiʻi kiʻi kiʻi loa = ka helu o nā pika kū pololei × ka nui i manaʻo ʻia (ma nā mika) × 1000

Kahua ʻike kū pololei × 17.45

or

Ka helu o nā pika kikoʻī × ka nui i manaʻo ʻia (i nā mika) × 1000

Kahua ʻike ākea × 17.45
