Proceedings of the Plenary and Lead Papers of the 25th Asian-Pacific Weed Science Society Conference. Volume 1:185-192. Interpretive Summary: Unmanned aerial vehicles (UAV) is a unique platform for remotely sensing crop fields that complements remote crop sensing from other platforms such as satellite, aircraft and ground-based platforms. Scientists in USDA ARS Crop Production Systems Research Unit in Stoneville, Mississippi developed and applied UAV-based systems for characterization of crop herbicide injury, crop yield estimation and crop field monitoring at multiple altitudes. Results indicate that UAV-based remote sensing not only inherits the state-of-the-art of remote sensing science and technology but also adds value to precision crop management and spray drift assessment.
Technical Abstract: Unmanned aerial vehicles (UAV) provide a unique platform for remote sensing to monitor crop fields that complements remote sensing from satellite, aircraft and ground-based platforms. The UAV-based remote sensing is versatile at ultra-low altitude to be able to provide an ultra-high-resolution image of crop fields to analyze the crop growth with two-dimensional visualization and three-dimensional reconstruction of the surface features of the crop fields. Also, UAV-based remote sensing is well controllable and adjustable to conduct multi-scale crop field monitoring for improved single-scale monitoring. This paper presents the UAV imaging systems we developed and used for characterization of crop herbicide injury, crop yield estimation and multi-scale crop field monitoring. Results illustrate that UAV-based remote sensing inherits the state-of-the-art of remote sensing science and technology and adds value to precision crop management and spray drift assessment.
