Zusammenfassung:The invention provides a crop lodging area proportion detection method and device. The method comprises the following steps: acquiring a satellite remote sensing image of crops in a working area; inputting the satellite remote sensing image into a lodging area proportion detection model to obtain a lodging area proportion detection result output by the lodging area proportion detection model; the lodging area proportion detection model is used for extracting spectral features and vegetation index features from a sample remote sensing image, determining a target scale grid unit based on the spectral features and the vegetation index features, determining sensitive features based on the target scale grid unit, and detecting the lodging area proportion. And training based on the sensitive features and the lodging area proportion sample data corresponding to the sensitive features. According to the crop lodging area proportion detection method and device provided by the invention, quantitative analysis of the cro
