Problems solved by technology

The reasons are as follows: 1) Aerial video generally has a small image size, and the range of the ground scene displayed by a single frame of video image is limited, so it is difficult to realize the panoramic observation of a large target area. 2) Aerial video has a high frame rate, a large degree of overlap between frames and irregular overlapping areas (caused by changes in flight attitude and speed), resulting in a large amount of image data and high difficulty in real-time accurate splicing

Abstract

The invention discloses a video image splicing method and device. Video image mosaic method of the present invention comprises the following steps: obtain video image; Adopt FFT-Mellin transform to judge the overlapping degree of video image adjacent frame, and select key frame according to overlapping degree; Carry out image registration to adjacent key frame; Will carry out Keyframe stitching for image registration into panoramas. The invention also discloses a video image splicing device.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a video image stitching method and device. Background technique [0002] As an important means of earth observation, aerial remote sensing has important applications in target reconnaissance, land monitoring and other fields. How to quickly process a large amount of data obtained by aerial remote sensing has become a hot research topic at present, among which aerial video stitching is the most concerned. The reasons are: 1) The aerial video is generally small in size, and the ground scene displayed by a single frame of video image is limited, so it is difficult to achieve panoramic observation of a large target area. A video stitching method is urgently needed to stitch multiple frames of images together to form a large-scale view. 2) Aerial video has high frame rate, large overlap between frames, and irregular overlapping areas (caused by changes in flight attitude and ...
