Abstract

The invention discloses a splicing line extraction method and device for image splicing. Wherein, the stitching line extraction method includes: acquiring the first image and the second image; determining the overlapping area of ​​the first image and the second image; Pixel difference operation to obtain the difference image of the overlapping area; calculate the smoothing factor of the image in the overlapping area to obtain the smoothing factor image; and extract the stitching line used to stitch the first image and the second image through the difference image and the smoothing factor image , which solves the problem that image stitching is prone to misalignment in the prior art, reduces the stitching misalignment phenomenon caused by registration deviation and different shooting angles, and improves the accuracy and efficiency of the optimal stitching line.

Description

technical field [0001] The present invention relates to the field of image stitching, in particular to a method and device for extracting stitching lines for image stitching. Background technique [0002] With the rapid development of aerospace remote sensing technology, remote sensing image stitching technology has also been widely used, and the demand for automatic remote sensing image stitching is becoming more and more urgent. Image stitching is also called image mosaic. As early as the 1970s, image mosaic technology appeared in the field of remote sensing technology. In order to obtain remote sensing images with a wider range and wider viewing angle, and to better process, analyze and study remote sensing image information uniformly, It is often necessary to stitch two or more remote sensing images with overlapping areas into an image map to form an overall image of the entire shooting area. The stitched image retains the detailed information in the original image, whic...
