Problems solved by technology
On the one hand, the shooting plan is cumbersome, requiring more than a dozen or even dozens of photos; on the other hand, so many photo errors will accumulate so much that automatic stitching cannot be done in the end, so it is a semi-automatic method. Often requires manual adjustment

The invention discloses a splicing method of a spherical panoramic video, which includes: acquiring a video pair shot by a fisheye lens; respectively performing a splicing operation on the first image and the second image having the one-to-one correspondence relationship as an image pair to form a splicing Video; that is, the automatic stitching of panoramic videos is realized by performing appropriate coordinate transformations on the video pairs captured by the fisheye lens. In the process of solving the transformation matrix, corner detection, empirical region search and HSV color space matching are required to realize the automatic detection of matching points; this method has a small number of shots, fast stitching speed, and no manual adjustment and intervention is required after the stitching process starts. The splicing effect of the generated video is good, the splicing of the middle seam position is accurate, and the transition is natural. Judging from the entire video playback, there is no image shake and misalignment. The invention also discloses a spherical panoramic video mosaic system, which has the above beneficial effects.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and system for splicing spherical panoramic videos. Background technique [0002] Panoramic video is a new type of video. Traditional video can only see information in a certain direction and range in space. Compared with this, panoramic video records 360-degree information in space and can interact with users to a certain extent, such as changing the viewing direction and switching scenes. It is stitched together from several common videos taken in different directions. Video stitching has important applications in military, medical, computer vision, video conferencing, security and other fields. Panorama video is developed from panorama. The stitching of panoramas has been studied more. [0003] According to different technical methods, the most commonly used methods can be divided into three categories: frequency domain-based methods, feature-based method...
