Embodiment Construction

[0030] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] One of the core concepts of the embodiments of the present invention is that when the mobile device plays a virtual reality video, the rotation matrix generated each time by the gyroscope of the mobile device is received in real time, and the rotation change matrix between each rotation matrix is ​​calculated, and Determine the playback angle adjustment amount of the virtual reality video played by the mobile device based on the rotation change matrix and the first rotation matrix generated when the gyroscope is turned off, thereby realizing the adjustment of the current playback angle of the virtual reality video played by the mobile device . The present invention realizes accurate control of the current playing angle of t...

Abstract

An embodiment of the invention provides a virtual reality video playing control method and apparatus. The method includes the steps of when a mobile device plays a virtual reality video, receiving and recording a first rotation matrix generated at a first time point when a gyroscope of the mobile device is switched off; receiving a second rotation matrix generated at a second time point when the gyroscope is switched on again, and receiving a third rotation matrix generated by the gyroscope after the second time point in real time; calculating a rotation variation matrix between the second rotation matrix and the third rotation matrix; conducting matrix calculation for the rotation variation matrix and the recorded first rotation matrix to obtain a matrix calculation result; and adjusting, based on the matrix calculation result, the current playing angle of the virtual reality video played by the mobile device. The invention can adjust the current playing angle of the video by calculating the rotation matrixes generated by the gyroscope, so as to more accurately and easily control the angle of the video and enhance the user experience.

Description

technical field [0001] The invention relates to the technical field of video control, in particular to a method for controlling virtual reality video playback and a device for controlling virtual reality video playback. Background technique [0002] When a user uses a mobile device (such as a mobile phone, a tablet computer, etc.) to play a virtual reality video, since the user is often in motion, it is easy to cause the user's perspective to change continuously, thereby causing discomfort to the user watching the video. Then, in order to improve the user's experience of the video being watched, it is usually necessary to control the angle of the video being played. [0003] Specifically, an existing technology for controlling the angle of a playing video is that the user uses different gestures to slide on the screen of the mobile device, so as to realize the angle rotation control of the currently playing video. But in this way, if the video is simply controlled by gestur...
