Ka mamao mākaʻikaʻi o ka lōʻihi lōʻihi zoom kamera module

Ma nā polokalamu nānā lōʻihi e like me ka pale kahakai a i ʻole antiUAV, pilikia pinepine mākou i nā pilikia: inā pono mākou e ʻike i nā UAV, nā kānaka, nā kaʻa a me nā moku ma 3 km, 10 km a i ʻole 20 km, he aha ke ʻano o ka lōʻihikōmi pahupaʻikiʻi zoompono mākou e hoʻohana?E hāʻawi kēia pepa i ka pane.

E lawe i ko makou lunamakaainanakōmi pahu pahu kiʻi zoom lōʻihihe laʻana.ʻO ka lōʻihi kiko300 mm (42x zoom module), 540 mm (90x zoom module), 860 mm (86x pahupaʻikiʻi zoom), 1200 mm (80x pahupaʻikiʻi zoom).Manaʻo mākou e ʻike ʻia ka pixel kiʻi ma 40 * 40, a hiki iā mākou ke kuhikuhi i nā hopena aʻe.

He maʻalahi loa ke ʻano.

E hoʻolilo i ka mamao o ka mea "l", ʻo ke kiʻekiʻe o ka mea "h", a ʻo ka lōʻihi kiko "f".e like me ka hana trigonometric, hiki iā mākou ke loaʻa l = h * (helu pika * ka nui pika) / F

ʻEhia mau pika e pono ai ma muli o ka algorithm ʻike hope.Inā hoʻohana ʻia ʻo 20 * 20 pixels e like me ka pixel ʻike ʻia, penei ka mamao ʻike.

No laila, ʻo ka ʻōnaehana maikaʻi ka hui pū ʻana o ka polokalamu a me ka lako.Hoʻokipa mākou i nā hoa hana algorithm ikaika e hana pū i nā huahana kamera nānā lōʻihi.
