Farmland corn straw satellite remote sensing extraction method and device

The invention provides a farmland corn straw satellite remote sensing extraction method and device, and the method comprises the steps: determining a normalized short wave infrared straw index NDSSI, a superposed infrared straw index AIRSI and a superposed near red straw index PNISI according to the reflectivity of each wave band of a target remote sensing image; according to the value range of any one or more of the NDSSI, the AIRSI and the PNISI, determining the corn straw area. According to the method, the farmland corn straw autumn and winter remote sensing monitoring result is determined through the three novel straw indexes including the normalized short-wave infrared straw index, the stacked infrared straw index and the stacked near-red straw index, the farmland corn straw extraction precision and efficiency can be improved, manual investigation is reduced, and data support is provided for straw incineration supervision. 本发明提供一种农田玉米秸秆卫星遥感提取方法及装置，该方法包括：根据目标遥感影像各波段的反射率，确定归一化短波红外秸秆指数NDSSI、叠加红外秸秆指数AIRSI和叠积
