Machine learning-based classification study of rice blast disease

Begin Rice, as the largest food crop grown in China, has shown a high incidence of rice blast disease, which seriously threatens the sustainability of rice production. A UAV multispectral remote sensing platform is used to realize the identification and monitoring of the incidence of rice blast disease and early warning at the field level, which assists variable fertilizer and drug application by plant protection UAVs. This research is based on a rice blast experiment in a large field in Wanchang Town, Yongji County, Jilin City, based on a malefactor, using a UAV multispectral remote sensing platform to obtain images of two fertility stages, namely, the nodulation stage(NS) and the spike stage(SS) of rice, and using six different vegetation index parameters as inputs to establish a DBO-XGBoost classification model, with an accuracy rate of more than 90% for both fertility stages.
