Title: Innovations in Drought Monitoring: The Contributions of Hanyu Liu
Introduction
Hanyu Liu is an innovative inventor based in Beijing, China. He has made significant contributions to the field of agricultural technology, particularly in drought monitoring for winter wheat. His work focuses on utilizing advanced remote sensing techniques to enhance agricultural productivity and sustainability.
Latest Patents
Hanyu Liu holds a patent for a "Rapid drought monitoring and identification method for winter wheat based on UAV measurements of leaf area index." This innovative method involves several key steps. First, it obtains multispectral images and ground-measured Leaf Area Index (LAI) through UAV-based multi-payload low-altitude remote sensing technology. It then calculates various vegetation indices, including Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI). The next step involves establishing regression equations between the calculated vegetation indices and measured LAI for different growth stages. This allows for the selection of the optimal model equation for each growth stage. Finally, the method uses the optimal model equation to invert the LAI of winter wheat at various growth stages, calibrating the LAI thresholds for different drought stress levels.
