Method for watching virtual reality video at preset view angle

Abstract

The invention relates to a method for watching virtual reality video at a preset view angle. The method comprises steps as follows: original data frames of video data in a panorama mode are acquired; a specific control parameter for determining a guidance view angle is added to each video data frame, and a parameter set is formed; a playing module performs 3D modeling; the playing module reads the video data frame by frame and releases the video data to a 3D model; the view angle mode is determined according to a control command input by a user for playing video information. Preset guidance view angle reference is provided during playing by adding specific control information to panoramic shot video frame by frame, and the user can watch the video in a guidance view angle mode except in the view angle mode selected by the user, thus, a great freedom degree is provided for the user during video watching. As the guidance view angle is usually the optimal view angle recommended after overall analysis and consideration of each frame of data, the user is also prevented from possibly missing highlights due to the free view angle, and the flexibility and the view experience of the user are greatly improved.

Description

technical field [0001] The present invention relates to a method for viewing virtual reality video with a preset viewing angle, in particular to a method in the technical field of virtual reality and video playback. Background technique [0002] With the rapid development of modern audio-visual technology, virtual reality is gradually sought after by people as a visual experience mode with a strong sense of immersion. Its feature is to provide 360-degree omnidirectional video information to users. Users interact with virtual reality video players through specific hardware devices, and input viewing angle control information in real time to realize free conversion of viewing angles. [0003] Although this viewing mode gives users the space to choose independently, it also has some shortcomings. For example, since the video data is all panoramic data without adding the photographer or director’s artistic editing, the user lacks a grasp of the overall perspective and easily mi...

AI Technical Summary

Problems solved by technology

For example, since the video data is all panoramic data without adding the photographer or director’s artistic editing, the user lacks a grasp of the overall perspective and easily misses the wonderful shot, resulting in a video that should have been wonderful but did not bring the user the desired experience. Some wonderful presentations; another example is that the user may not have a viewing angle at all times, but has to make actions at all times because of the need to give viewing angle instructions, otherwise it will be played continuously from a single angle, which also brings a lot of trouble to the user. a lot of inconvenience
