Description

A head-mounted display device

technical field

The utility model relates to virtual reality technology, in particular to a head-mounted display device.

Background technique

Virtual reality technology is the use of computer technology as the core combined with photoelectric sensing technology to generate realistic visual, audio, and touch-integrated virtual environments within a specific range (such as aircraft cockpits, molecular structure worlds, and high-risk environments). If specific equipment is used (motion acquisition degree of freedom space positioning, force feedback input, digital helmet, three-dimensional display environment, etc.), it can naturally interact with objects in the virtual world in real time and realistically, thereby generating the feeling and experience of being on the scene.

In recent years, with the gradual maturity of virtual reality technology, various virtual reality devices have appeared one after another, such as three-dimensional scanners and head-mounted display devices. Socializing through VR is one of the popular uses for VR.

When performing social activities, some users will have the need to show their environment to the other party they are communicating with, such as letting friends see their newly renovated home or the beautiful scenery around them, but the existing equipment is not very good. Well meet this need. Although some devices are equipped with cameras, they are usually only installed with one camera, which can only capture part of the scene. If users in different places want to observe the scene they are in, they can only follow the camera to observe the scene instead of panorama. Like the video, you can choose where you want to watch.

detailed description

A head-mounted display device according to an embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.

It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

Referring to Fig. 1 , an embodiment of a head-mounted display device of the present invention includes a display device 1 and a head fixing device 2; the display device 1 is installed on the head fixing device 2, and the head-mounted display device is also At least two camera devices 3 are included, and the at least two camera devices 3 are arranged on the head restraint device 2 and/or the display device 1 at a distance from each other.

The head-mounted display device provided by the embodiment of the utility model includes at least two camera devices arranged at intervals on the head fixing device and/or the display device, so that it can be viewed from more directions and relatively Completely capture video images of the scene where the user is located.

In the foregoing head-mounted display device embodiments, the display device 1 may be a display device in an existing head-mounted display device, for example, it may include related display elements and optical elements.

In the aforementioned embodiment of the head-mounted display device, the head fixing device 2 includes: a first fixing part 21 and a second fixing part 22; each of the first fixing part 21 and the second fixing part 22 includes a fixing end and a free end and the arc portion connecting the fixed end and the free end; the first fixing part and the second fixing part surround an annular space for fixing the user's head; the at least two camera devices 3 is arranged on the first fixing part 21 and/or the second fixing part 22, and the photographing direction faces the outside of the first fixing part and/or the second fixing part.

In the aforementioned embodiment of the head-mounted display device, the camera device 3 may use a camera in the prior art. The number of cameras can be determined according to the shooting range of a single camera, that is, the viewing angle. For example, if the viewing angle (FOV, Field of Vision) of a camera is large, the spacing can be enlarged. If it is necessary to obtain a panoramic video image of the scene where the head-mounted display device is located, and the FOV of the camera can reach 180 degrees, then only two cameras installed at an angle of 180 degrees apart are required.

Preferably, the scenes captured by the arranged cameras can be combined to obtain a panoramic video image of the scene where the head-mounted display device is located.

Referring to FIG. 2 , as a preferred embodiment, the camera device 3 , that is, the number of cameras is four, and the shooting ranges of adjacent cameras are just connected or partially overlapped.
