Ibanga lokuqapha lemojuli yekhamera yebanga elide lokusondeza

Ebangeni elide ukuqapha izicelo ezifana nokuvikela ugu noma antiI-UAV, sivame ukuhlangana nezinkinga ezinjalo: uma sidinga ukuthola ama-UAV, abantu, izimoto nemikhumbi ku-3 km, 10 km noma 20 km, hlobo luni lobude obugxileimojuli yekhamera yokusondezakufanele sisebenzise?Leli phepha lizonikeza impendulo.

Thatha ummeleli wethuimojuli yekhamera yebanga elide lokusondezanjengesibonelo.Ubude bokugxila bu300 mm (imojuli yokusondeza engu-42x), 540 mm (imojuli yokusondeza engu-90x), 860 mm (ikhamera yokusondeza engu-86x), 1200 mm (ikhamera yokusondeza engu-80x).Sicabanga ukuthi i-pixel yokuthwebula iyabonakala kokuthi 40 * 40, futhi singabhekisela emiphumeleni elandelayo.

Ifomula ilula kakhulu.

Ibanga lento mayibe ngu-“l”, ukuphakama kwento kube “h”, futhi ubude bokugxila kube “f”.ngokuya ngomsebenzi we-trigonometric, singathola l = h * (inombolo yephikiseli* usayizi wamaphikseli) / F

 

Iyunithi (m) I-UAV abantu izimoto
I-SCZ2042HA(300mm) 500 1200 2600
I-SCZ2090HM-8(540mm) 680 1600 3400
I-SCZ2086HM-8(860mm) 1140 2800 5800
I-SCZ2080HM-8(1200mm) 2000 5200 11000

 

Mangakhi amaphikseli adingekayo kuncike ku-algorithm yokuqaphela ngemuva.Uma amaphikseli angu-20 * 20 esetshenziswa njengephikseli ebonakalayo, ibanga elitholakalayo limi kanje.

Ngakho-ke, uhlelo oluhle kakhulu kufanele lube inhlanganisela yesoftware nehardware.Samukela ozakwethu abanamandla be-algorithm ukuze babambisane ukuze bakhe imikhiqizo yamakhamera eqapha ibanga elide ndawonye.
