Abstract
This paper focused on UAV remote sensing technology,with an emphasis on analyzing its platform types and sensor configurations,technical advantages and characteristics,as well as its specific applications in agricultural fields such as crop identification,growth monitoring,pest and disease detection,and yield estimation.UAV remote sensing platforms include fixedwing UAVs,multirotor UAVs;sensor types include multispectral cameras,hyperspectral cameras,LiDAR,thermalinfrared cameras,visiblelight cameras,etc.With the coordination of platforms and sensors,the system responds rapidly and deploys flexibly,supporting diverse takeoff and landing methods and recovery modes,enabling rapid deployment to target areas for monitoring.The integration of multi-source sensors and real-time processing enables the acquisition of high-resolution spectral imagery and farmland spatial information.Specific agricultural applications of UAV remote sensing include:precise crop identification by fusing spectral,textural,and spatial features,combined with object-oriented classification or improved deep learning models to achieve high-precision automatic recognition of crop types;crop growth monitoring by calculating indices such as NDVI from multispectral imagery,combined with SVM,random forest,and other models to achieve quantitative assessment of crop growth status;pest and disease detection based on thermal infrared and multispectral imagery through threshold segmentation,feature extraction,and machine learning classification to achieve early detection and assessment of diseases;and yield estimation through extracting vegetation indices and texture features from multispectral imagery combined with machine learning to construct predictive models.This paper provides a reference for the development and application of UAV remote sensing technology in agriculture.关键词
