Method and system for panoramic video stabilization, and portable terminal
The present application is applicable in the field of videos. Provided are a method and system for panoramic video stabilization, and a portable terminal. The method comprises: acquiring in real time the timestamp of a current state, an accelerometer count value, and an angular velocity value of a portable terminal; estimating the rotation vector of the current state by utilizing an Extended Kalman Filtering combined with the accelerometer count value and the angular velocity value; calculating a current rotation matrix via the Rodrigues' rotation formula on the basis of the rotation vector of the current state; and rotating a panoramic image on the basis of the current rotation matrix and producing a stabilized video frame. The present invention allows the stabilization of a jittering video frame and alleviates VR motion sickness.
