Abstract

The invention discloses a mobile phone terminal VR scene interactive display method based on cloud rendering. VR scenes can be watched on a mobile phone in combination with VR mobile phone glasses. According to the method, a sensor of a mobile phone is used for measuring the rotation angle of the head of a viewer, and a measurement result is transmitted to a rendering cloud so as to adjust the forward observation direction and the upward direction of a left eye virtual camera and a right eye virtual camera, so that a VR scene is interactively viewed on the mobile phone. According to the method, a binocular inhibition theory principle is utilized, different image resolutions are used when left and right eye pictures are drawn, and the three-dimensional picture drawing time and the image network transmission data volume can be reduced. By using the method, the VR scene can be watched only through a mobile phone browser without installing other plug-ins or a single mobile phone APP.

Description

technical field [0001] The invention belongs to the technical field of virtual reality and multimedia webpage development, and relates to a method for interactively displaying VR scenes at a mobile phone terminal based on cloud rendering. Background technique [0002] In recent years, virtual reality (VR) technology has developed rapidly. Using VR mobile glasses can transform a smartphone into a simple head-mounted virtual reality display device. CARDBOARD proposed by Google engineers in 2014 is the earliest VR mobile phone glasses. Most of the current VR mobile phone glasses products are improved based on the working principle of CARDBOARD. The head-mounted virtual reality display device formed by the combination of VR mobile phone glasses and smart phones has the advantages of convenient movement and low price, and is widely welcomed by consumers. The calculation overhead of drawing realistic VR scene images is very high. Smartphones have limited computing power, and it...
