The first mounting portion 2 is connected to the stand 1 and configured to mount the head mounted display device 4. The second mounting portion 3 is connected to the stand 1 and configured to mount the image pickup device 5. In a state where the imaging apparatus 5 is mounted on the second mounting portion 3 and the head mounted display device 4 is mounted on the first mounting portion 2, the camera of the imaging apparatus 5 can be positioned within the eyebox 41a of the head mounted display device 4.

The head-mounted display device provided by the embodiment of the present disclosure may be any one of VR (Virtual Reality), AR (Augmented Reality), and MR (Mixed Reality). In the AR case, the virtual picture may be anchored to a certain position in reality in the AR experience, that is, the virtual picture may be fixed relative to the real world in the user experience. The user may walk around the virtual picture while wearing the head mounted display device 4 to observe the virtual picture in different orientations. The user can hold the sharing frame disclosed by the invention to simulate the user walking scene shooting picture, and the real scene picture and the virtual picture are shot simultaneously through the camera device 5, so that the real experience that the user wears AR glasses can be restored.

The eye box generally refers to an optimal region where the eye can observe that the optical imaging system of the head-mounted display device can image, and is generally a cone-shaped region of a solid.

Referring to fig. 11, a possible optical imaging system is shown. For example, the optical imaging system is disposed within the head mounted display device 4, and may include an image source assembly 42 and an optical assembly. The image source assembly 42 is configured to emit light capable of forming an image, and the optical assembly is configured to change a light path of the light emitted from the image source assembly 42 and project the light toward a first side direction of the image source assembly 42, so that the light can be projected into an eye of a user when the head-mounted display device is worn on the head of the user, thereby forming an image in the eye of the user. The optical assembly may include an arcuate optic 43 and a flat optic 44. Light can be thrown to vertical direction along image source subassembly 42, and straight lens 44 can be with the light refraction back that image source subassembly 42 sent, to second side direction throw light, and arc lens 43 reflects the back to the light that straight lens 44 throws, throws light to first side direction, and light can pass straight lens 44 to when the user wears wear-type display device, throw in user's the eye, thereby form virtual image in the user field of vision. After wearing the head-mounted display device, the user sees the real world and the virtual picture added in the real world at the same time. For example, virtual cartoon characters are placed on a real-world table, or virtual images and videos are displayed in a field of view, etc.

Referring to fig. 12, the eyebox 41a of the head mounted display device shown in fig. 11 is substantially a tapered region expanding from the left region shown in the figure to the right head mounted display device. After the user wears the head-mounted display device, the eyes are substantially located within the eyebox 41a to obtain the best visual experience. In the process of the design, the eye box range of the head-mounted display device is referred to, so that the camera device and the head-mounted display device are both installed in the state that the head-mounted display device experiences the sharing frame, the camera of the camera device can be located in the eye box range of the head-mounted display device, and the virtual image can be collected, and meanwhile, the real world image which penetrates through the arc-shaped lens 43 and the straight lens 44 can be collected. It can be understood that the whole camera may be located within the eye box 41a, or a part of the camera may be located within the eye box 41a, or the camera may be close to the eye box 41a, as long as it is ensured that the camera can clearly capture the required image.
