The invention discloses a farmland segmentation and crop identification method based on cross-granularity remote sensing fusion, and belongs to the technical field of agricultural remote sensing and intelligent farmland management. The method comprises the following steps: firstly, acquiring and preprocessing a high-resolution fine-grained image and a multi-temporal medium-low-resolution coarse-grained image of a target area; performing over-segmentation by using the fine-grained image to generate a super-pixel object and constructing a graph structure model; extracting a core region through morphological corrosion to form a core object, and distinguishing a farmland region from a non-farmland region; taking the kernel object as a unit, and extracting a multi-dimensional feature set covering a crop growth cycle from the coarse-grained image; carrying out crop type identification by adopting a machine learning classifier based on the kernel object features; and finally, mapping the identification tag back to the super-pixel object, and generating a plot level classification map with accurate plot boundary and crop category information after boundary optimization. According to the method, the advantages of remote sensing data with different spatial resolutions are fused, so that the comprehensive precision and practicability of plot segmentation and crop identification in a complex farmland area are effectively improved.
