Satellite image-based farmland boundary extraction method and device, electronic equipment and storage medium

The invention discloses a satellite image-based farmland boundary extraction method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining a satellite imageof a farmland environment; dividing the farmland environment into three conditions: (1) the color of a region in the farmland is uniform, and the color difference between a non-farmland region and the region in the farmland is greater than a set threshold; (2) the color of the field road is a fixed color; (3) a common farmland environment without environmental characteristics; aiming at the threefarmland environments, three corresponding boundary extraction methods are respectively provided: (1) a boundary extraction method of a morphological filling road area; (2) a boundary extraction method for extracting a fixed color; and (3) a boundary extraction method for screening boundary points and fitting. According to the method, the thought of conventional unified processing is broken through, and the detection prec
