The invention belongs to the technical field of building remote sensing image recognition, and discloses a high-resolution remote sensing image contour multistage regularization method and system and application. The method comprises the steps of obtaining an approximate building area according to a segmentation result, constructing an optimal enclosing rectangle conforming to a building shape based on a main direction, and performing primary regularization processing on a contour in combination with a Hausdorff distance algorithm; then, grouping least square straight line fitting is carried out by utilizing key point information, and connection and reconstruction of all line segments are carried out by utilizing a sensing marshalling algorithm under the constraint of the main direction of the building; and realizing regularization of all building contours in the high-resolution image by using a graph search algorithm. Experimental comparative analysis is carried out on a plurality of remote sensing images, t
