UAV-Borne Dual-Band Sensor Method for Monitoring Physiological Crop Status
Unmanned aerial vehicles (UAVs) equipped with dual-band crop-growth sensors can achieve high-throughput acquisition of crop-growth information. However, the downwash airflow field of the UAV disturbs the crop canopy during sensor measurements. To resolve this issue, we used computational fluid dynamics (CFD), numerical simulation, and three-dimensional airflow field testers to study the UAV-borne multispectral-sensor method for monitoring crop growth. The results show that when the flyingdoi:10.3390/s19040816 fatcat:57hyytxegvfjxlzqxalypeel5u
