DJI Phantom 4 - Multispectral

DJI specializuotas dronas Phantom 4 Multispectral, ypač tinkantis panaudoti agro kultūroje įsivertinant augalų augimo vegetacijos procesą bei galimybė sukurti jo 3d žemėlapį, kad geriau paskirstyti trašas bei purškimą. Dėl naujos kartos sistemų matavimo duomenys realiu laiku gaunami centimetrų tikslumu. Užtikrintas skrydžio signalas ir stabilumas net ir tose vietovėse, kuriuose daug signalo trukdžių. Valdymo pultas su pritvirtintu ryškiu ekranu.

Image Position Compensation

The relative positions of the centers of the six cameras’ CMOS and the phase center of the onboard D-RTK antenna have been calibrated and are recorded in the EXIF data of each image.

Mapping Functions

Ground Sample Distance (GSD)

(H/18.9) cm/pixel, H indicates the aircraft altitude relative to the area mapped (unit: m)

Rate of Data Collection
