Effect of camera orientation angle on UAV crop assessment accuracy

Reflectance indices are very important for precision agriculture. The impact of the orientation angle error when shooting the integrated cameras in the DJI Mavic 2 pro and DJI Phantom 4 pro, as well as an additional mounted MAPIR camera, was investigated. The deviations in the omega/phi/kappa angle uncertainty of the absolute camera positions are analyzed. The relationship between wind speed and camera orientation angle errors was calculated. A strong correlation was obtained R Square is 0.79.
