Abstract

The invention discloses a VR video display method, a VR video display device and a terminal. The method comprises the steps of acquiring a VR panoramic source video; building a running environment ofa graphic processing program via an Apple graphics library context object, and running the graphic processing program; loading the VR panoramic source video to the graphic processing program via a graphics library texture loading method; aiming at each frame in the VR panoramic source video, mapping the VR panoramic source video to a spherical surface model via the graphic processing program; acquiring a current angle information; selecting a partial planar graph corresponding to the selected angle information from the spherical surface model; and rendering and displaying the partial planar graph. According to the method, the device and the terminal provided by the invention, the VR panoramic source video can be normally played on an IOS operating system, and thus the user using the IOS operating system can acquire the normal VR experience.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a VR video display method, device and terminal. Background technique [0002] At present, in recent years, with the surge of VR (Virtual Reality, virtual reality technology), the concept of VR has been recognized more and more, and VR products have emerged in an endless stream. VR has gradually entered people's lives. As a brand-new video market, VR panoramic video has a huge commercial value, and its importance as a currently popular researched VR technology can also be seen. However, the mobile phone of the IOS operating system (developed by Apple) in the related art cannot normally display the VR panoramic source video. When the user watches the VR panoramic source video through the mobile phone of the IOS operating system, the video frame often looks Distorted or broken, which seriously affects the user experience. Contents of the invention [0003] In view of this...
