Zusammenfassung: | The invention discloses a dynamic identification method and system based on abandoned mine ecological restoration. According to the dynamic recognition method for mine ecological restoration, the RGB value Cij in any pixel area in the remote sensing image serves as an independent variable, the reference value of the influence factor in the remote sensing image obtaining process serves as a dependent variable, a regression model is built, the RGB value Cmn of the pixel area in the remote sensing image is calculated, and therefore a correction coefficient zeta is obtained; and correcting each pixel region in the remote sensing image to be identified, and extracting a normalized difference vegetation index (NDVI) of the corrected remote sensing image so as to complete dynamic identification of abandoned mine ecological restoration. The influence of deviation between the obtained vegetation region image and the actual vegetation region area caused by interference factors such as external environment and air tempe |
