Iyo yekutarisa chinhambwe cherefu renji zoom kamera module

Mumarefu ekutarisa maapplication akadai semahombekombe ekudzivirira kana antiUAV, tinowanzosangana nematambudziko akadai: kana tichida kuona maUAV, vanhu, motokari uye zvikepe pa3 km, 10 km kana 20 km, rudzii rwekurebazoom kamera moduletinofanira kushandisa?Bepa rino richapa mhinduro.

Tora mumiriri wedukureba kureba zoom kamera modulesemuenzaniso.Kureba kwefocal ndiko300 mm (42x zoom module), 540 mm (90x zoom module), 860 mm (86x zoom kamera), 1200 mm (80x zoom kamera).Isu tinofungidzira kuti iyo yekufungidzira pixel inozivikanwa pa40 * 40, uye isu tinogona kutaura kune inotevera mhedzisiro.

Iyo fomula iri nyore kwazvo.

Rega chinhambwe chive “l”, kureba kwechinhu kuve “h”, uye kureba kwacho kuve “f”.zvinoenderana nebasa retrigonometric, tinogona kuwana l = h * (pixel nhamba* pixel saizi) / F

 

Chikamu (m) UAV vanhu motokari
SCZ2042HA(300mm) 500 1200 2600
SCZ2090HM-8(540mm) 680 1600 3400
SCZ2086HM-8(860mm) 1140 2800 5800
SCZ2080HM-8(1200mm) 2000 5200 11000

 

Mangani mapixels anodiwa zvinoenderana neiyo back-end recognition algorithm.Kana 20 * 20 pixels akashandiswa sepixel inozivikanwa, kureba kwekuona kunotevera.

SCZ2090HM-8(540mm) 1360 3200 6800

SCZ2080HM-8(1200mm) 4000 10400 22000

 

Saka, yakanakisa sisitimu inofanirwa kuve musanganiswa wesoftware uye hardware.Isu tinogashira vane simba algorithm vadyidzani kuti vabatane kugadzira makuru akareba ekutarisa zvigadzirwa zvekamera pamwechete.
