Remote sensing data-based cultivated land boundary identification system and method

The invention relates to the technical field of cultivated land boundary extraction, and discloses a cultivated land boundary recognition system and method based on remote sensing data. A data acquisition module shoots a target area at intervals of a period through unmanned aerial vehicle remote sensing and acquires m pictures, and then the m pictures are spliced through a picture splicing module; m pictures shot each time are spliced into complete real image data, then the red light reflectivity and the near-infrared reflectivity in the complete real image are extracted through a feature extraction module, and a feature analysis module extracts a cultivated land area image in each complete real image based on the red light reflectivity and the near-infrared reflectivity; and then the feature extraction module continues to extract gray values of all suspected cultivated land boundary areas in each cultivated land area image, and the feature analysis module calculates a boundary recognition coefficient based o
