Abstract

The invention relates to a method and system for detecting field angle of a virtual reality display device. The method comprises the following steps: 1) selecting a panoramic image, format and optical parameters of which are matched with those of a detected virtual reality display device according to the detected virtual reality display device; 2) loading a test pattern to the panoramic image to generate a panoramic image having scale marks, and importing the panoramic image having the scale marks to the detected virtual reality display device; and 3) obtaining a horizontal field angle by observing the scale marks at the left and right boundaries of the panoramic image of the detected virtual reality display device, and / or obtaining a vertical field angle by observing the scale marks at the upper and lower boundaries of the panoramic image of the detected virtual reality display device. The method is suitable for all virtual reality display devices, is accurate in reading, and has the advantages convenient, direct, fast and efficient detection of the field angle of the detected virtual reality display device.

Description

technical field [0001] The invention relates to a method and system for detecting the viewing angle of a virtual reality display device. Background technique [0002] Virtual reality (referred to as VR), that is, the use of computer technology to simulate the three-dimensional virtual world of the real environment, allowing users to perceive things in the virtual space in a timely and unlimited manner. Recently, emerging technologies represented by Oculus and other manufacturers have given birth to the upsurge of the VR industry. Google, Tencent, Huawei and other domestic and foreign giants have deployed VR equipment and platform research and development. With the penetration of various fields, various VR acquisition devices, content production platforms, VR interactive technologies, VR helmets and VR applications are constantly emerging, so that 2016 is called "the first year of VR industrialization". [0003] With the continuous development and application of VR display d...
