Abstract

The invention discloses a tracking method and a tracking apparatus for a panoramic video moving direction. The method is performed through the following steps: determining the moving direction of a camera by conducting pixel tracking to the right lower part of a panoramic video of a spherical model from a cloud terminal or a server terminal, obtaining data on the moving direction, and storing the obtained data on the moving direction in the server terminal or the cloud terminal separately. When a request is made from a user's terminal for a video file containing the data on the moving direction, the server terminal or the cloud terminal sends the video data to the user's terminal in accordance to the request and transmits the data on the moving direction at the same time so that the current playing visual angle can be tuned. According to the invention, the tracking method enables a user to move to a camera, and this means that he or she does not have to slide their fingers or turn around to change a current playing visual angle.

Description

technical field [0001] The present invention relates to the technical field of video playback, in particular to a tracking method and a tracking device for a panoramic video motion direction. Background technique [0002] Panoramic video is based on 360 panoramic technology to convert static panoramic pictures into dynamic video images, so that video viewers have a truly immersive feeling, and it is not limited by time, space and region, so it is very popular. Currently, in a panoramic video, the default positive direction of the video is in the middle of the video. When the player is playing a panoramic video, the default starting angle of view points to the above positive direction. Then, the user needs to change the video by sliding his finger or rotating the user himself. Playback angle of view. However, when the panoramic camera is placed on a moving object or the cameraman moves, the user often wants to automatically move with the movement of the camera, but the exist...
