Abstract
The present invention provides an anti-shake method for a panoramic video, which comprises: obtaining, in real time, an output video frame, a fisheye image corresponding thereto, a pixel timestamp in the video frame, and a corresponding camera gyroscope timestamp; synchronizing the pixel timestamp in the video frame with the corresponding camera gyroscope timestamp, and calculating a rotation matrix of the camera movement in the camera gyroscope timestamp; smoothing the camera movement and establishing a coordinate system of a smooth trajectory; correcting the fisheye image distortion; and rendering the fisheye image by means of forward rendering to generate a stable video. According to the present invention, the rolling shutter distortion of a panoramic video sequence can be corrected, the image distortion caused by the rolling shutter of a CMOS can be corrected, and the rolling shutter is eliminated, thereby achieving a better anti-shake effect of a video image.
