Near-real-time remote sensing monitoring method for phenology of crops

The invention discloses a near-real-time remote sensing monitoring method for crop phenology, and belongs to the technical field of remote sensing monitoring. The method comprises the following steps: acquiring a limited VI time sequence curve of a current year and a complete VI time sequence curve of a historical year of a crop; generating a shape model of the current year; obtaining a complete VI time sequence curve of N same crop pixels; selecting a complete VI time sequence curve of which the correlation coefficients of the limited VI time sequence curve and the complete VI time sequence curve of the target pixel are ranked before 10; 10 first phenological estimation values are obtained by using an SMF-S method, and 10 second phenological estimation values of the target pixel in the current year are obtained by combining the optimal translation step length; and selecting a median of the second phenological estimation values as a detection result.
