Abstract

Embodiments of the present application disclose a fusion method, device and equipment for image splicing. The method includes: performing image registration on images to be spliced; determining the distance between the first image and the second image in the registered image to be spliced. Overlapping areas; perform grayscale fitting on the grayscale values ​​of the overlapping areas; divide the overlapping areas into blocks after grayscale fitting to obtain multiple areas to be fused; fuse each area to be fused to obtain the fusion The final stitched image. In the embodiment of the present application, by using the method of detecting edge lines, the overlapping areas of the images to be spliced ​​can be quickly and accurately found, grayscale fitting is performed on the grayscale values ​​​​of the overlapping areas, and the grayscale fitting is performed. The overlapping areas are divided into regular blocks, and then curve-weighted fusion is performed on each area to be fused after dividing the blocks, ensuring that all boundaries of the overlapping areas are smoothly transitioned, solving the problem of splicing seams, and improving the quality of the spliced ​​image. Visual effect.

Description

technical field [0001] The present application relates to the technical field of image mosaic processing, and in particular to an image mosaic fusion method, device and equipment. Background technique [0002] Image stitching is to stitch two or more partially overlapping images to form a large format or wide viewing angle image. In stitching images, there is often a stitching seam problem, that is, a transition line that appears at the junction of adjacent images. This transition line is caused by fusion during splicing. In the fusion of existing mosaic images, commonly used fusion methods include: substitution method, weighted average method, curve weighting method and so on. [0003] However, the replacement method is to replace the overlapping area of ​​the two images with one of the images, which is prone to seam problems. The weighted average method is to weight and average the overlapping areas of two images according to a certain ratio. Although the seam problem c...
