Abstract

The invention provides a panoramic video data processing method and device, and the method comprises the steps of determining a reference polar coordinate of a central position of a target object in a spherical polar coordinate system under the condition of receiving a frame selection operation for the target object of which a current video frame is located at the center of a playing plane image; generating a tracking plane image of the next video frame by taking the reference polar coordinate as a center according to the panoramic image of the next video frame in the spherical polar coordinate system; determining an updated polar coordinate of the central position of the target object in the tracking plane image of the next video frame in the spherical polar coordinate system according to the object features of the target object; and taking the updated polar coordinate as a reference polar coordinate, and returning to execute the operation step of generating the plane image of the next video frame by taking the reference polar coordinate as a center according to the panoramic image of the next video frame in the spherical polar coordinate system until a tracking stop condition is reached, thereby obtaining a reference polar coordinate sequence corresponding to the current video frame to the target video frame.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to a panoramic video data processing method. The present application also relates to a panoramic video data processing device, a computing device, and a computer-readable storage medium. Background technique [0002] With the rapid development of computer technology and image processing technology, panoramic video came into being. The shooting and production of panoramic video are becoming more and more popular. Many video websites also use panoramic video as a special category for users to choose and watch. . Panoramic video is a dynamic video that is captured by a panoramic camera and contains 360-degree all-round picture content. It converts static panoramic pictures into dynamic video images, and users can freely watch dynamic videos within the shooting angle range of the panoramic camera. [0003] In the prior art, if the creator of the panoramic video want...
