Latest Patents

Chen's latest patents include a "Rapid drought monitoring and identification method for winter wheat based on UAV measurements of leaf area index." This innovative method involves obtaining multispectral images and ground-measured Leaf Area Index (LAI) through UAV-based multi-payload low-altitude remote sensing technology. It calculates various vegetation indices such as NDVI, DVI, RVI, EVI, OSAVI, and Transformed Chlorophyll Absorption Reflectance Index. The method establishes regression equations between the calculated vegetation indices and measured LAI for different growth stages, allowing for the inversion of LAI values and calibration of drought stress levels.

Another notable patent is the "Rapid UAV-based monitoring and discrimination method for drought in summer maize based on chlorophyll content." This method also employs UAV technology to obtain multi-spectral imagery and measure chlorophyll content on the ground. It constructs regression equations with measured chlorophyll content during different growth stages, enabling the retrieval of chlorophyll content and assessment of real-time drought levels.
