Problems solved by technology

[0002] Most of the existing automatic image registration and correction technologies perform image stitching after each image is registered and corrected. If there is a small amount of image stitching, this method can be used for image registration and correction, but if It is the automatic stitching of massive images, and this method highlights its limitations. For example, the overall geometric accuracy of the images needs to be changed. It is time-consuming and labor-intensive to correct all of them, and it is also prone to error transmission
At the same time, although the existing technology has processed the feathered area in the overlapping area on the stitched image to correct the pixels in the feathered area, it is not necessary to stitch the image after the registration is corrected, but the stitched There will still be pixel misalignment in the image

Abstract

The present application provides an automatic correction method, device, electronic device and storage medium for overlapping images. The method includes: obtaining a feathered area to be corrected. The feathered area is located in the same geographical location on two spliced ​​images. Partial areas within the overlapping area; based on the feathering area, correct the pixels in the feathering area located on the first feathering area on one of the two images; using the first feathering The feather edge line on one side of the area close to the non-overlapping area on the one image is the starting line, and the transition area is determined on the one image according to the predetermined transition distance; the transition area is located on the Within the overlapping area; correct the coordinates of the pixels in the transition area. This can reduce the complexity of image processing and at the same time improve the position misalignment of pixels in the spliced ​​image.
