Abstract

The present invention discloses a method and device for correction of a panorama video display visual angle. The method comprises: obtaining a panorama video and an attitude angle data sequence corresponding to the panorama video; aiming at the frame panorama images of the panorama video, patching the panorama video to a presetting three-dimensional geometrical feature surface, obtaining a panorama display body, and finding out the attitude angles corresponding to the panorama images from the attitude angle data sequence; and performing rotation of the panorama display body of the panorama images according to the found attitude angles to eliminate the image rotation caused by the shooting shaking. The method and device for correction of the panorama video display visual angle can eliminate the generated frame shaking, jittering or rotation when the panorama video is shot to allow the playing video frame to always keep stable so as to increase viewers' watching experience.

Description

technical field [0001] The invention relates to virtual reality technology, in particular to a method and device for correcting the display angle of a panoramic video. Background technique [0002] Panoramic shooting can shoot left, right, up and down 360-degree video at the shooting position, so that the viewer has an immersive feeling. In the prior art, a panoramic shooting device collects external images through two fisheye lenses or multiple wide-angle lenses, and then stitches them together through an algorithm to form a panoramic video. [0003] In the process of actual shooting, especially in the state of motion, the shooting equipment will shake or shake a little, which will cause the same shaking or shaking in the display screen of the captured video, resulting in unstable playback pictures , the viewer's viewing experience is greatly reduced. Contents of the invention [0004] In order to solve the above technical problems, the present application provides a me...
