High-resolution satellite remote sensing image mosaic line extraction method and system

The invention provides a high-resolution satellite remote sensing image mosaic line extraction method and system, and belongs to the field of image processing, and the method comprises the steps: extracting a public region on a first image S1 and a second image S2, and recording the public region as an image P; the first image S1 and the second image S2 are two high-resolution satellite remote sensing images to be inlaid; distributing an energy value for each pixel on the image P through a preset energy function; constructing an energy matrix E for the image P based on the distributed energy value; extracting a path with the minimum sum of all energy in the energy matrix E as a mosaic path; and based on the mosaic path, drawing in the image P to obtain a mosaic line. The mosaic line extracted by the method can be prevented from penetrating through ground objects, can be directly used for mosaic without manual intervention and modification, and can be widely applied to mosaic of remote sensing images with high
