Problems solved by technology

[0005] This leads to a problem. Shared viewers will find that the objects in the real scene and the virtual display objects have a difference in viewing angle and spatial position, which is different from the real experience of the user of AR glasses, especially the visual experience. The virtual object directly touched by the user with bare hands will appear to be untouched at a relatively high camera angle of view, because there is a gap between the virtual and real combination under the camera's perspective and the virtual and real combination under the user's perspective of AR glasses.

Embodiment 1

[0053] The invention discloses a screen projection device for single-plate reflective AR glasses. The realization principle of the existing single-plate reflective AR glasses is as follows: figure 1 As shown, the light of the real world 80 enters the eye 100 through the semi-reflective flat lens 30, and the projection device 20 projects the virtual object on the semi-reflective flat lens 30, and enters the eye 100 after being reflected by the semi-reflective flat lens 30 , so as to achieve the effect of augmented reality; the appearance of single-plate reflective AR glasses is as follows figure 2 As shown in the figure, the single-plate reflective AR glasses are also provided with a protective transparent layer, and the protective transparent layer is provided with a light-reducing liquid crystal layer or a silver bromide interlayer, and the light-reducing liquid crystal layer The depth of the liquid crystal display is set according to the adjustment command, and the silver b...

Embodiment 2

[0056] like Figure 4 and Figure 7 As shown, on the basis of the existing single-plate reflective AR glasses, the micro-camera 50 is arranged on the same side of the projection device 20 and placed adjacently in parallel. The plane mirror 31 is arranged on the opposite side of the projection device 20 , and the micro camera 50 and the plane mirror 31 are arranged on both sides of the semi-reflective and semi-transparent plane lens 30 . After the light of the real world 80 is reflected by the semi-reflective and semi-transparent plane lens 30, it enters the plane mirror 31, and then after the reflection of the plane mirror 31 and the perspective of the semi-reflective and semi-transparent plane lens 30, it enters the micro camera 50; The projection device 20 projects the virtual object on the semi-reflective and semi-transparent plane lens 30, after being transmitted by the semi-reflective and semi-transparent plane lens 30, it is injected into the plane mirror 31, and then t...

Embodiment 3

[0058] like Figure 5 and Figure 7 As shown, on the basis of the existing single-plate reflective AR glasses, the micro-camera 50 is arranged on the same side of the projection device 20 and placed adjacently in parallel. The concave mirror 32 is arranged on the opposite side of the projection device 20 , and the micro camera 50 and the concave mirror 32 are arranged on both sides of the semi-reflective and semi-transparent plane lens 30 . After being reflected by the semi-reflective and semi-transparent plane lens 30, the light of the real world 80 enters the concave reflector 32, and then after the reflection of the concave reflector 32 and the perspective of the semi-reflective and semi-transparent plane lens 30, it enters the micro camera 50; The projection device 20 projects the virtual object on the semi-reflective and semi-transparent plane lens 30, after being transmitted by the semi-reflective and semi-transparent plane lens 30, it is injected into the concave refle...

Abstract

The invention discloses a screen projection device of single-plate reflection type AR glasses. The system comprises at least one projection device and at least one optical device; the optical device comprises at least one planar lens; a real image is constructed through the optical device, a virtual image is constructed after being reflected in the optical device through the projection device, andat least one micro camera is included and used for acquiring the real image and the virtual image at the same time and transmitting image information to external display equipment in a wired or wireless communication connection mode. According to the invention, a screen projection scheme of the original single-plane lens reflection type AR glasses is overcome, or when external camera equipment isused, the equipment is heavy, and the equipment is presented only at the third visual angle instead of the first visual angle when in use can be solved.

Description

technical field [0001] The present invention relates to a head-mounted display device, and more specifically, to a near-eye see-through head-mounted display optical system and a camera system of an AR display device. Background technique [0002] Since the emergence of computer-generated image technology and the development of overlay technology with the real world, AR (augmented reality, augmented reality) and VR (virtual reality, virtual reality) have changed the traditional way of perception and interaction. No longer just interacting with digital information, but perceiving and interacting with the entire society. With the continuous advancement of design concepts, manufacturing levels and micro-display technology, AR display devices are entering various fields, such as entertainment, simulation training, and medical fields. [0003] The head-mounted display in the existing technology is only used by one person. To let more people know the effect of its use, it is gener...
