Abstract

The invention discloses a video splicing method based on a minimum boundary distance. The method mainly involves performing interframe registering on source video frames by use of a scale invariant feature transform algorithm, then detecting motion objects based on a minimum boundary distance algorithm and carrying out video fusion. The method provided by the invention can effectively overcome interference of such objective factors as illumination, ghosting artifacts and the like, and has the advantages of excellent splicing effect, concise calculation, simple parameter arrangement and the like.

Description

technical field [0001] The invention relates to a video mosaic method based on minimum boundary distance, and belongs to the technical field of image processing and image fusion. Background technique [0002] With the rapid development of the national economy, the important role of transportation, image and video applications in people's daily life is highlighted, and the issue of large field of view images and videos has attracted more and more attention from social media and people. [0003] Video stitching is a technology that collects video data with overlapping areas through two or more cameras according to a certain camera calibration technology, so that the output result has a wider field of view. At present, video stitching technology and its application are one of the new research hotspots in the fields of virtual reality and computer vision. It is mainly used in live broadcast, video surveillance, panorama fusion, super large image sampling and so on. Existing vid...
