A method is provided for panoramic video stabilization by using an angle sensor, which comprises the following steps of (1) obtaining an initial rotation angle by using the collecting unit of the angle sensor before video capturing; (2) allowing the angle sensor to work synchronously with a video capturing device, and obtaining the rotation angle data of each frame of captured panoramic video; (3) if the video capturing device jitters or rotates, calculating the difference between the rotation angle of the current video frame and the initial rotation angle; (4) correcting the current video frame by using the calculated difference in rotation angle, thereby implementing the video stabilization of the panoramic video capturing device. The inventive method can efficiently eliminate the videojitters caused by the deviation and rotation of the video capturing device during the panoramic video capturing process.
Description
Method of Correcting Panoramic Video Jitter Using Angle Sensor technical field The present invention relates to the technical field of panoramic video, and more specifically, to a method for correcting shaking of panoramic video by using an angle sensor. Background technique Panoramic images are stitched together using multiple live-action images taken at one point. The specific generation process is: mapping overlapping images reflecting their respective projection planes onto simple geometric surfaces, such as spheres, cubes or cylinders, so that the plane images have a sense of depth, and then seamlessly splicing the projection images, you can A panoramic image without image distortion is obtained. When the user observes a certain image space, the corresponding part of the panoramic image should be back-projected onto the observation plane to produce correct observation results for the user. Panoramic images provide users with a great degree of freedom of observation,...
