Nyob rau hauv kev saib xyuas kev ncua ntev xws li kev tiv thaiv ntug hiav txwv lossis kev tiv thaiv UAV, peb feem ntau ntsib cov teeb meem xws li: yog tias peb yuav tsum kuaj UAVs, tib neeg, tsheb thiab nkoj ntawm 3 km, 10 km lossis 20 km, qhov ntev focal ntev npaum li cas. zoom koob yees duab module peb yuav tsum siv? Daim ntawv no yuav muab cov lus teb.

Coj peb tus neeg sawv cev Ntev ntau zoom lub koob yees duab module ua piv txwv. Lub focal ntev yog 300mm (42x zoom module), 540mm (90x zoom module), 860mm (86x zoom lub koob yees duab), 1200mm (80x zoom lub koob yees duab). Peb xav tias cov duab pixel pom tau ntawm 40 * 40, thiab peb tuaj yeem xa mus rau cov txiaj ntsig hauv qab no.

Cov mis yog yooj yim heev.

Cia qhov deb ntawm qhov khoom yog "l", qhov siab ntawm qhov khoom yog "h", thiab qhov ntev focal yog "f". Raws li kev ua haujlwm trigonometric, peb tuaj yeem tau txais l = h * (pixel naj npawb * pixel loj) / F

Yuav tsum muaj pes tsawg pixels nyob ntawm lub back-kawg paub algorithm. Yog tias 20 * 20 pixels siv raws li qhov pom tau pixel, qhov kev tshawb pom deb yog raws li hauv qab no.

Yog li, qhov zoo tshaj plaws yuav tsum yog kev sib xyaw ntawm software thiab kho vajtse. Peb zoo siab txais tos cov neeg koom tes muaj zog algorithm los koom tes los tsim cov khoom siv ntev ntev saib xyuas lub koob yees duab ua ke.
