Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in related technologies: the field of view (Field of View) of the existing augmented reality display system is usually relatively small, and the user cannot efficiently interact with the virtual image information. In addition, the existing augmented reality display system also has the problem of large volume and weight and inconvenient portability.

Embodiment 1

[0031] refer to Figure 1a , an augmented reality display system provided by an embodiment of the present invention, the augmented reality display system has a total weight of less than 350 grams, and includes: a head-mounted frame 11 , two display modules 12 , and two see-through light guide elements 13 . Wherein, the see-through light guide element 13 is an optical synthesis device with partial transmission and partial reflection.

[0032] The display module 12 and the see-through light guide element 13 are both arranged on the head-mounted frame 11 , and the bracket 11 fixes the display module 12 and the see-through light guide element 13 . The display module 12 is arranged on the upper side of the see-through light guide element 13 , and the light emitted by the display module 12 can pass through the see-through light guide element 13 and be reflected. Optionally, the display module 13 can also be located at the side of the see-through light guide element 13 .

Abstract

The embodiment of the invention discloses an augmented reality display system, which comprises a head-mounted frame, a display module, two perspective light-guiding elements and a mainboard, wherein the display module, the two perspective light-guiding elements and the mainboard are arranged on the head-mounted frame. The embodiment of the invention has the beneficial effects that with the concavesurfaces of the two perspective light-guiding elements, first light including virtual image information of the left eye and second light including virtual image information of the right eye are reflected into the eyes of a user as much as possible, so that a visual feeling of a 3D virtual scene is formed in the brain of the user, and the visual area is large. In addition, third light which includes external image information and is transmitted via the convex surfaces and concave surfaces of the perspective light-guiding elements enters the eyes of the user, so that the user can see the external real scene, and thus a visual feeling of mixing the 3D virtual scene and the real scene is formed.

Description

technical field [0001] The embodiments of the present invention relate to the field of augmented reality technology, in particular to an augmented reality display system. Background technique [0002] The augmented reality display system is a new technology developed in recent years. According to specific applications, it is mainly divided into two types: VR (Virtual Reality, virtual reality) and AR (Augmented Reality, augmented reality). The principle of AR is to simulate virtual vision through an augmented reality display system and superimpose it on the user's normal vision. At present, the AR augmented reality display system has two implementation methods: optical see-through and video see-through, the main difference of which lies in the different optical synthesis devices. [0003] Among them, the optical synthesis device in the optical see-through augmented reality display system can be a partly transmissive and partly reflective element, the light from the real envi...
