Embodiment Construction

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0060] Please refer to the attached figure 1 and figure 2 It is a schematic diagram of a panoramic video frame and a normal video frame. The present invention proposes a video classification method. By extracting N frames of video frames in a video file, the video frame attribute of each video frame is judged, and according to the video frame attributes of the N frames of video frames, it is judged that it is specifically a panoramic video or an ordinary vid...

Abstract

The invention discloses a video classification method and a video classification system; the method includes steps of extracting N video frames in the video file according to a preset method, wherein N is integer and odd number; according to the aspect ratio of every video frame, confirming the video frame property of the vide frame; according to the property of the N video frame, confirming the video property of the video file. Through extracting the N video frame in the video file, the video frame property of every video frame is judged; according to the video frame property of the N video frame, the full view video or ordinary video can be particularly judged; through the video classification method and system, the automatic classification of the video file can be realized; according to the classification result, the video type is marked, and the method can check if the video type label marked artificially is correct, thereby avoiding the display experience of full view video by false classification of images, and further enhancing the display experience of users in watching the full view video.

Description

technical field [0001] The invention belongs to the technical field of video classification, and more specifically relates to a video classification method and system. Background technique [0002] In recent years, VR (Virtual Reality, virtual reality) has become the most concerned technology. VR refers to a computer simulation system that can create and experience a virtual world. It uses various means to simulate and generate a virtual environment, so that users can experience interactive three-dimensional dynamic scenes and physical behaviors in the virtual environment. System Simulation. As one of the key technologies, the playback of panoramic video has always been the direction in which major video content providers have invested the most energy. [0003] At present, video content providers have opened up the panoramic video upload service for PGC (Professionally-generated Content, professionally produced content) users, and support immersive playback of panoramic vi...
