Embodiment 1

[0047] like figure 1 As shown, it is a schematic flowchart of the method for automatically recognizing a cube panoramic video in this embodiment. The method in this embodiment solves the technical problem that the existing technology cannot automatically recognize a cube panoramic video. The method for playing a panoramic video based on a cube model described in this embodiment includes the following steps:

[0048] Step 101. In the player, set a variance threshold for determining gap pixel pairs of the cubic panoramic video.

[0049]Cube panoramic video refers to the technology of attaching the obtained panoramic video images to the panoramic video mapping surface of the cube model, and then selecting the corresponding mapping image according to the user's viewing angle position to display and play in the playback window. However, in the prior art, there is no technology for automatically identifying and playing a cube panoramic video, and the user is required to manually se...

Embodiment 2

[0060] Such as figure 2 As shown, it is a schematic flow chart of the method for automatically recognizing cube panoramic video in this embodiment. On the basis of Embodiment 1, this embodiment describes the specific content of judging and playing cube panoramic video, spherical panoramic video and plane video. The method for automatically identifying cube panoramic video described in this embodiment includes the following steps:

[0061] Step 201. In the player, set a variance threshold for determining gap pixel pairs of the cubic panoramic video.

[0062] Preferably, the variance threshold is greater than or equal to 90.

[0063] Step 202, acquire video image frames from the database and calculate the aspect ratio of the image frames.

[0064] Step 203, when the aspect ratio of the image frame is 3:2, obtain the pixels of the gap pixel pair according to the position of one-third of the width, two-thirds of the width and one-half of the height of the image frame , and cal...

Embodiment 3

[0077] Such as image 3 As shown, it is a schematic structural diagram of the system for automatically recognizing a cube panoramic video in this embodiment, and the system in this embodiment is used to implement the method for automatically recognizing a cube panoramic video in the above embodiment. The system for automatically identifying cube panoramic video in this embodiment includes: a setting module 301 , a video image frame acquisition module 302 , a calculation module 303 and a cube panoramic video judging module 304 .

[0078] Wherein, the setting module 301 is coupled with the video image frame acquiring module 302, and is used to set the variance threshold for determining the gap pixel pairs of the cubic panoramic video in the player. Preferably, the variance threshold is greater than or equal to 90.

[0079] The video image frame acquisition module 302 is coupled with the setting module 301 and the calculation module 303, and is used to acquire video image frames...

Abstract

The invention discloses a method for automatically identifying a cubic panoramic video. The method comprises the following steps: setting a variance threshold used for judging interval pixel pairs of the cubic panoramic video in a player; obtaining an image frame of the video from a database, and calculating an aspect ratio of the image frame; when the aspect ratio of the image frame is 3:2, obtaining the pixels of the interval pixel pairs according to a 1 / 3 width position, a 2 / 3 width position and a 1 / 2 height position of the image frame, and calculating a pixel variance of the interval pixel pairs; and when the pixel variances of the 1 / 3 width position, the 2 / 3 width position and the 1 / 2 height position of the image frame reach or exceed the number of the variance threshold of the interval pixel pairs or exceeds 2, judging the video as the cubic panoramic video. By adoption of the method, the cubic panoramic video is automatically identified.

Description

technical field [0001] The present invention relates to the technical field of video playback, and more specifically, to a method and system for automatically recognizing cube panoramic videos. Background technique [0002] Panoramic video, that is, 720-degree or 360-degree panoramic video, is developed and extended on the basis of 720-degree or 360-degree panoramic technology. It converts static panoramic pictures into dynamic video images. Panoramic video can be shot up, down, left, and right. View dynamic videos in a 360-degree range, allowing users to have an immersive feeling. When making a panoramic video, a group of cameras is used to shoot 360-degree (or 720-degree) images around the shooting point at the same time, and after image stitching in the later stage, it can show the video of the surrounding images of the shooting point without distortion at any time. [0003] At present, there is no specific format for saving panoramic videos, and the existing panoramic v...
