Embodiment 1

[0060] Such as figure 1 As shown, it is a schematic flowchart of the method for automatically identifying and playing a panoramic video in this embodiment. In this embodiment, whether the aspect ratio of the video frame image based on the video is 2:1 excludes a part of the non-panoramic video, and then according to the pixel pair color value variance and The pixel color correlation of the left and right edge columns further judges whether it is a panoramic video, which achieves the purpose of automatically identifying and playing the panoramic video and improves the accuracy of identifying the panoramic video. The method for automatically identifying and playing a panoramic video described in this embodiment includes the following steps:

[0061] Step 101, setting the variance threshold, the average threshold of the edge column pixel pair color difference and the local fluctuation coefficient threshold of the edge column pixel pair color difference for judging the panoramic ...

Embodiment 2

[0075] Such as image 3 As shown, it is a schematic flowchart of the method for automatically identifying and playing a panoramic video described in this embodiment. On the basis of Embodiment 1, the present embodiment illustrates the automatic determination of whether it is a panoramic video through the correlation between the color value of the edge row pixel pair and the color value of the edge column pixel pair, and automatically distinguishes the panoramic video or ordinary plane video. The specific content played in the corresponding mode. The method for automatically identifying and playing a panoramic video described in this embodiment includes the following steps:

[0076] Step 301, setting the variance threshold, the average threshold of the color difference of the edge column pixel pair and the local fluctuation coefficient threshold of the edge column pixel pair color difference for judging the panoramic video in the player.

[0077] Preferably, the variance thre...

Embodiment 3

[0100] Such as Figure 6 As shown, it is a schematic structural diagram of a system for automatically identifying and playing a panoramic video in this embodiment. The system for automatically identifying and playing a panoramic video described in this embodiment may implement the method for automatically identifying and playing a panoramic video in the foregoing embodiments. The system for automatically identifying and playing panoramic video described in this embodiment includes: an identification setting module 601, a video acquisition module 602, a first calculation module 603, a second calculation module 604, and a video playback module 605; wherein,

[0101] The recognition setting module 601 is coupled with the first calculation module 603 and the second calculation module 604, and is used to set the variance threshold for judging the color difference between the edge row pixels of the panoramic video in the player , the average threshold of the color difference betwee...

Abstract

The invention discloses a method for automatically identifying and playing panoramic videos. The method includes the steps: acquiring a video image frame in video data, and calculating the width-height ratio of the video image frame; respectively acquiring a color value of a margin row pixel pair and a color value of a margin line pixel pair in the video image frame when the width-height ratio of the video image frame is 2, and calculating an average value of color difference values of the margin line pixel pair and an average local fluctuation coefficient of the color difference values of the margin line pixel pair when variances of color difference values of the margin row pixel pair are smaller than or equal to variance threshold values of the color difference values of the margin row pixel pair; generating corresponding mapping spherical surfaces according to the video image frame to play when the average value of the color difference values of the margin line pixel pair is smaller than or equal to an average threshold value of the color difference values of the margin line pixel pair and a local fluctuation coefficient of the color difference values of the margin line pixel pair is larger than or equal to a local fluctuation coefficient threshold value of the color difference values of the margin row pixel pair. By the method, the panoramic videos are automatically identified and played.

Description

technical field [0001] The present invention relates to the technical field of panoramic video identification, and more particularly, to a method and system for automatically identifying and playing panoramic video. Background technique [0002] Panoramic data, including panoramic video, has become one of the current hot research topics. 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 are used to shoot 360-degree (or 720-degree) images around the shooting point at the same time, and after image stitching and stitching in the later stage, it can show the video of the surrounding images of the shooting point without...
