Abstract

The embodiment of the present invention discloses a fusion method, fusion device and fusion equipment of image splicing. The fusion method provided by the invention comprises: performing image registration of an image to be spliced; determining an overlapping region of a first image and a second image in the registered image to be spliced; performing gray fitting of the gray value of the overlapping region; partitioning the overlapping region after gray fitting, and obtaining a plurality of regions to be fused; and fusing each region to be fused, and obtaining a fused splicing image. In the embodiment of the present invention, an overlapping region of an image to be spliced may be quickly and accurately found through an edge line detection mode; gray fitting of the gray value of the overlapping region is performed, and regular partitioning of the overlapping region after gray fitting is carried out; and curve weighting fusion of each region to be fused obtained after partitioning is performed. Therefore smooth transition of all the boundaries of the overlapping region is ensured, the seam stitching problem is solved, and the splicing image visual effect is improved.

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...
