Abstract

The invention provides a video splicing apparatus and a video splicing method based on image splicing. The video splicing method based on image splicing comprises the following steps: obtaining a first path of videos and a second path of videos to be spliced; respectively extracting a feature point corresponding to each frame of image in n frames of images in the first path of videos and the second path of videos; sequentially splicing the ith frame of image of the first path of videos and the ith frame of image of the second path of videos according to the feature point of the ith frame of image of the first path of videos and the feature point of the ith frame of image of the second path of videos to obtain a spliced video; and displaying the spliced vide. According to the video splicingmethod based on image splicing provided by the invention, the features of the two paths of videos are extracted and executed to improve the splicing efficiency and the splicing stability.

Description

technical field [0001] The present invention relates to the technical field of video image splicing, in particular to a video splicing device and a video splicing method based on image splicing. Background technique [0002] The current video stitching technology is mainly used in the field of real-time video surveillance in the transportation industry, and the research is mainly focused on the stitching of traffic surveillance videos where the camera position is relatively fixed and the camera is placed close to the decent. But in fact, with the development of computer vision, such as VR, 360-degree panoramic camera, etc., the application field of video stitching technology has gradually expanded to the field of military investigation, civilian consumer entertainment fields such as film and television, games, etc. The relatively mature stitching algorithm is the stitching of static images. [0003] At present, many monitoring situations require long-distance, unobstructed ...
