Document Type and Number:
WIPO Patent Application WO/2019/052534
Kind Code:
A1
Abstract:
An image stitching method and device, and a storage medium. The method comprises: obtaining a first overlap image and a second overlap image (S101), wherein the first overlap image is an area overlapping a second image in a first image, the second overlap image is an area overlapping the first image in the second image, and the first image and the second image are adjacent images to be stitched; determining a motion vector from each pixel in the first overlap image to a corresponding pixel in the second overlap image, to obtain an optical flow vector matrix (S102); on the basis of the optical flow vector matrix, remapping the first overlap image to obtain a first remapping image and remapping the second overlap image to obtain a second remapping image (S103); and fusing the first remapping image and the second remapping image to obtain a stitched image of the first overlap image and the second overlap image (S104).
