Abstract

The invention relates to a method for playing a virtual reality (VR) panoramic video. The method comprises the following steps: shooting the existing picture by shooting equipment to acquire flat panoramic video stream; acquiring and decoding the planar panoramic video stream into a video frame by a panoramic video player; establishing a 2D spherical model according to the horizontal and vertical direction field angle of a shooting lens; performing spherical angle segmentation to acquire a 2D spherical model and generate a spherical surface vertex array; connecting all the spherical surface vertexes to form grids, establishing a three-dimensional model described by the grids and establishing a visible grid set; adhering texture of the corresponding grids; setting a pyramid frustum near plane, a far plane, a viewpoint and an API interface according to the panoramic video payer to obtain the size of a screen viewport; and drawing the planar panoramic video stream on the screen according to the size and the initial position coordinates of each split screen window of left and right split screens to realize panoramic video playing. By the method, VR equipment can display images accurately in real time.

Description

technical field [0001] The invention relates to the technical field of panoramic video, in particular to a method for playing virtual reality panoramic video. Background technique [0002] With the rapid development of VR (Virtual Reality, or VR) display technology, a variety of display devices have emerged, and users have higher and higher requirements for display device selection. Panoramic video has entered the public eye. [0003] In order to realize the playback of panoramic videos, a 360-degree virtual reality interactive player (VR device) is developed on the basis of traditional 2D video players. The device creates an immersive virtual experience that is both private and human by playing 360-degree real-life video stored in the form of digital signals. In order to improve user experience, VR devices can not only present virtual reality scenes to users, but also play videos through the video playback interface. At present, the size and position of the video playback...
