Embodiment Construction

[0081] At present, VR devices mainly have two types: non-adjustable viewing distance and adjustable viewing distance. Compared with non-adjustable viewing distance VR devices, adjustable viewing distance VR devices can better meet the needs of users such as myopia and hyperopia. However, whether it is a VR device with a non-adjustable viewing distance or a VR device with an adjustable viewing distance, there may be a problem that the user's field of view does not match the virtual content's field of view. The main reasons are as follows:

[0082] 1. Assembly tolerance of VR equipment.

[0083] refer to figure 1 As shown, the optical structure of most VR devices is screen + lens. In actual operation, VR devices are generally assembled according to the preset reference screen-lens distance between the screen and the lens. However, due to the difference between the screen and the lens There are differences in specifications and installation methods. The distance between the lens...

Abstract

The invention discloses a virtual content display method and device, a VR device and a medium, which are applied in the technical field of VR to solve the problem of scene drift in the prior art. Specifically, the method comprises the steps of obtaining the distance between the screen of the VR device and the lens; determining a visible area of the lens on the screen according to the distance, anddetermining a screen display area according to the visible area; acquiring a position of the human eye relative to the lens; determining a user field angle of view corresponding to the position, andadjusting the field angle of view of the virtual content according to the user field angle of view; displaying the virtual content after adjusting the field of view angle on the screen display area. Thus, the adaptive adjustment of the view angle of the screen display area and the virtual content is realized, so that the view angle of the screen display area is consistent with the visible area andthe view angle of the virtual content is consistent with the view angle of the user, thereby effectively reducing the probability of the scene drift occurrence and improving the visual effect of theVR device as much as possible.

Description

technical field [0001] The present invention relates to the field of virtual reality (Virtual Reality, VR) technology, and in particular to a virtual content display method, device, VR device and medium. Background technique [0002] VR technology is a combination of simulation technology, computer graphics, man-machine interface technology, multimedia technology, sensor technology, network technology and other technologies. With the continuous development of VR technology, various VR devices such as VR goggles have appeared. The device generates a three-dimensional virtual scene through computing simulation, which can bring users an immersive experience in terms of vision, hearing, touch and other senses, thereby realizing a new experience. [0003] However, in practical applications, due to the assembly tolerance of the VR device and the deviation of the user, there may be a problem that the user's field of view does not match the virtual content's field of view when the u...
