I nā noi lōʻihi lōʻihi e like me ke kahakai kahakai a iʻole anti UAV, we often encounter such problems: if we need to detect UAVs, people, vehicles and ships at 3 km, 10 km or 20 km, what kind of focal length Hoʻokomoʻo Zoom Carming Module pono mākou e hoʻohana? E hāʻawi kēia pepa i ka pane.

E lawe i kā mākouʻelele ʻO ka modon lōʻihiʻo Zoom me he kumu hoʻohālike. ʻO ka lōʻihi ka lōʻihi 300 mm (42x zoom module), 540 mm (90x zoom module), 860 mm (86x zoom samom), 1200 mm (80x zoom samom). ^. Manaʻo mākou uaʻikeʻia ka pixel i loaʻa i ka 40 * 40, a hiki iā mākou ke kuhikuhi i nā hopena aʻe.

He maʻalahi loa keʻano.

E lilo i ka mea e "L" E like me ka hana trigonometric, hiki iā mākou ke loaʻa l = H * (pixel helu * pixel helu) / F

Ehia mau pikika e pono ai ke hilinaʻi ma hope o ka hope. Inā hoʻohanaʻia 20 * 20 mau pikika e like me ka pixel iʻikeʻia, ka lōʻihi o kaʻike.

No laila,ʻo ia ka'ōnaehana maikaʻi e pono ke hui pūʻana o ka polokalamu a me nā lako. Ua hauʻoli mākou i nā mea hana algorithm algorithm e hana pū e hana i nā huahana kelepona lōʻihi e pili pū ana i nā huahana
