Summary: | The invention provides a road edge extraction method and device based on a remote sensing image, and the method comprises the steps: obtaining a target remote sensing image which is a remote sensing image comprising a road, carrying out the preprocessing of the target remote sensing image, carrying out the preliminary segmentation of the road and background in the target remote sensing image, and carrying out the segmentation of the road and background in the target remote sensing image; generating a segmented image; noise coarse elimination is carried out on the segmented image, pixel-by-pixel judgment and road edge and background area marking are carried out on the segmented image after noise coarse elimination, the road edge is extracted, and an edge extraction image is generated; and according to a preset noise pixel capture sliding window comprising a plurality of scales, capturing and eliminating patch noise in the edge extraction image, and generating an optimized edge extraction image. In this way, on |
