Document Type and Number:
WIPO Patent Application WO/2022/127225
Kind Code:
A1
Abstract:
The present application provides an image stitching method and apparatus, and a device and a storage medium. The method comprises: acquiring an original image to be processed, the original image consisting of a plurality of sub-images collected by a plurality of collectors; in the original image, dividing the image of a non-overexposed region into an overlapping region and a non-overlapping region, the overlapping region being a region where the pixel coordinates of the plurality of sub-images overlap each other in the original image; separately performing pixel processing on the overlapping region and the non-overlapping region to generate first pixel information of the overlapping region and second pixel information of the non-overlapping region; and performing image stitching on the overlapping region and the non-overlapping region according to the first pixel information and the second pixel information to generate a stitched image of the original image. According to the present application, the grid noise of the stitched image is reduced, so that the stitched image is more continuous and smoother.
