Summary: | The invention provides a seam line network generation method based on a grid. The method comprises the following steps: determining the effective range of each image to be inlaid; acquiring the coverage area of a final inlaid result according to an effective range polygon of each image, and creating a template image of the same size, and initializing a pixel digital number; sequentially inlaying the images to the template images, assigning corresponding values; carrying out region growing on overlapping areas one by one to obtain seam lines in each overlapping area; processing all the overlapping areas, and connecting the formed seam lines to obtain the final seam line network. The seam line network generation method based on the grid disclosed by the invention is applicable to automatic generation of the seam line network when digital orthoimages are inlaid to solve the problems of the seam line network generation when the effective ranges of the images are in arbitrary shapes.
