Giám sát Cây trồng bằng Drone

Agricultural drones: eyes in sky revolutionize farming! Drone capabilities: (1) Multispectral cameras (RGB visible + NIR near-infrared sensors), (2) NDVI mapping (Normalized Difference Vegetation Index healthy green vs. stressed yellow/red), (3) Thermal imaging (water stress detection before visible), (4) 3D terrain modeling (elevation, drainage patterns), (5) Real-time HD video (scout 100 hectares in 20 minutes vs. days walking!). Applications: pest/disease detection (spot infestations early treat locally not spray entire field!), irrigation assessment (identify dry zones), growth monitoring (compare fields over time), yield estimation (predict harvest AI models), crop counting (plants per hectare), damage assessment (hail, flood, wildlife).

Technology: DJI Agras (market leader spraying drones 16L tank covers 10 hectares/hr), Parrot Bluegrass/Sequoia (multispectral sensing), PIX4D software (process images into actionable maps), autonomous flight (GPS waypoints pre-programmed routes). Economics: drone service $5-15 per hectare (affordable even small farms), own drone $1K-20K depending sensors, ROI 1-2 seasons (catch problems early save losses, input savings 10-30%). Regulations: FAA Part 107 US (pilot license required), EASA EU, CAAV Vietnam (registration, line-of-sight).

Future: AI analysis (automated disease detection computer vision), swarm operations (multiple drones coordinate), spraying precision (reduce pesticides 90%!). Climate adaptation: monitor crop stress droughts, early warning systems. Precision agriculture from above!
