Abstract

The present application provides a panoramic video data processing method and device, wherein the panoramic video data processing method includes: determining the reference polar coordinates of the target border of the frame-selected target object in the current video frame when the center of the target object is detected to enter the fixed viewing angle area ;According to the panoramic image of the next video frame in the spherical polar coordinate system, with the reference polar coordinates as the center, generate the tracking plane image of the next video frame; take the next video frame as the current video frame, return to execute according to the next video frame For the panoramic image in the spherical polar coordinate system, the reference polar coordinates are the center, and the operation steps of generating the tracking plane image of the next video frame until the center of the target object leaves the fixed viewing angle release area. In this way, as long as the target object does not leave the fixed viewing angle release area, the corresponding plane image will always be generated with the same polar coordinates as the center, thereby effectively eliminating the inaccurate tracking effect caused by the target object moving at a large angle.

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, when tracking a target object in a panoram...
