Provided are a panoramic video anti-shake method and a portable terminal. The method comprises: acquiring world coordinates of any reference point in a world coordinate system in real time, and also acquiring the corresponding camera coordinates of the reference point in the portable terminal and an angular velocity value of a gyroscope at a current state in the portable terminal; smoothing the motion of a camera by using an extended Kalman filter; decomposing the smoothed motion, synthesizing the motion into a virtual lens motion in an ePTZ mode, and calculating a rotation amount of the virtual lens; and re-projecting an original video according to the rotation amount of the virtual lens and a rotation matrix for converting from the camera coordinates to the world coordinates, so as to generate a stable video."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Panoramic video anti-shake method and portable terminal","description":"The present invention is applicable to the field of videos.
