Embodiment 1

[0113] Aiming at the problem in the prior art that when the client jumps to play the video corresponding to the point of interest of the panoramic video, the region where the point of interest occurs cannot be played for the user, which leads to the poor experience of the user watching the panoramic video, the embodiment of the present invention provides a panoramic video Video playback method, such as figure 2 As shown, the method includes:

[0114] S201. The client terminal determines that the user selects to jump to play the video corresponding to the jump time point in the panoramic video.

[0115] The client may determine through interaction with the user that the user chooses to jump to play the video corresponding to the jump time point in the panoramic video. For example, the client detects that the user drags or clicks the progress bar of the panoramic video to a certain point in time, or the client determines that the user fast-forwards to a certain point in time t...

Embodiment 2

[0173] Aiming at the technical solution for the client to play the panoramic video for the user in the prior art, there is no method for the client to display the thumbnails of the relevant frames near the point of interest in the panoramic video for the user, which leads to the problem that the user has a poor experience watching the panoramic video An embodiment of the present invention provides a method for playing a panoramic video, so that a client can display thumbnails of relevant frames near a point of interest in a panoramic video for a user.

[0174] In this embodiment, the video playing system includes a client and a server. In this embodiment, the thumbnail may be generated by the client through the method provided in this embodiment, or the thumbnail may be generated by the server through the method provided in this embodiment, and then the client displays the thumbnail for the user.

[0175] Such as Figure 7A As shown, the embodiment of the present invention prov...

Embodiment 3

[0209] Based on the first embodiment above, the embodiment of the present invention also provides a panoramic video playback device, which can adopt figure 2 Corresponding to the method provided in Embodiment 1, the apparatus is applied to a client. refer to Figure 11 As shown, a panoramic video playback device 1100 includes: a jump determination unit 1101 , a point of interest matching unit 1102 , an angle of view determination unit 1103 , and a jump playback unit 1104 . Optionally, the device 1100 also includes an information acquisition unit 1105 . in,

[0210] The jump determination unit 1101 is configured to determine the video corresponding to the jump time point in the panoramic video selected by the user to jump and play.

[0211] The point of interest matching unit 1102 is configured to match the jump time point determined by the jump determining unit 1101 with the time range in which each point of interest in at least one point of interest included in the panoram...

Abstract

A method for playing a panoramic video, which is used to solve the problem of being unable to locate the region where the point of interest occurs in the existing technical solution for the client to play the panoramic video for the user. The method includes: the client determines that the user selects to jump to play the video corresponding to the jump time point in the panoramic video; the client matches the time point with the time range of occurrence of each point of interest in at least one point of interest included in the panoramic video ; When the matched point of interest falls within the time range of a point of interest, the client determines the user angle of view where the matched point of interest occurs in the panoramic area of ​​the panoramic video; the The client acquires the video corresponding to the time point when the user's perspective is adopted in the panoramic video, and jumps to play the video corresponding to the time point when the user's perspective is adopted.

Description

technical field [0001] The present invention relates to the field of multimedia technologies, in particular to a panoramic video playback method and device. Background technique [0002] Panoramic video is also called 360-degree video. Panoramic video is obtained by using multiple cameras to shoot the environment to obtain multiple video streams, and then synthesize multiple video streams through synchronization, splicing, projection and other technologies. Panoramic video includes Information about the environment, up, down, left, right, front and back. [0003] Limited by the viewing angle range of the human eye (about 120 degrees) and the viewing angle range of the video display device (for example, the viewing angle range of the head-mounted device is usually 96-110 degrees), when the user watches the panoramic video, the user can only watch the panoramic video. For some areas of the panoramic area, the user can view different positions of the panoramic area in the pano...
