Drone-based Monitoring of Sunflower Crops

Remote monitoring and utilization of digital technologies is essential for the application precision farming approach, which contributes significantly to improved quality agricultural products. The paper compares data six vegetation indices when observing sunflower in South Dobrudzha 2021. Images with RGB NIR camera were obtained via a remotely piloted quadcopter. flight plan specifies speed 8 m/s, altitude 100 m shooting overlapping images 80%. Six indices: NDVI, EVI2, SAVI, CVI, MGVRI MPRI calculated from during flight. calculation takes into account intensity solar radiation parameters meteorological situation at time shooting. findings reveal stable trend change indices, thus, establishing accurate reliable results as areas unmanned aerial vehicles.
