Problems solved by technology

[0003] At present, there are related augmented reality products on the market. Under the existing technical conditions, most of these products use the method of projecting virtual images to an infinite distance from the human eye for observation. This can meet the needs of some scenarios, but the long-term Wearing it will cause eye fatigue, nausea and vomiting and other physiological phenomena, which is the vergence-accommodation conflict mention

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0033] like figure 1 As shown, the augmented reality display device includes an image source 1, a projection system 2, a multilayer reflective electric control grating 3, and a control unit. The image source 1 produces an image to be displayed, and the light of the image is projected onto the multi-layer reflective electric control grating 3 through the projection system 2, and the image light is adjusted by the reflective electric control grating 3 to produce enlarged virtual images of different depths that are captured by the human eye. 4 perception.

[0034] The image source 1 can be a flat or curved microdisplay, or a phase-type spatial light modulator.

[0035] The projection system 2 can adopt existing technology, and preferably has optical properties such as small numerical aperture and large depth of field.

[0036] like figure 2 ...

Abstract

The invention discloses an augmented reality display device capable of rapidly switching image depths. The device comprises an image source, an imaging unit and a control unit, wherein the image source is used for generating an image with a corresponding depth; the imaging unit includes several depth regulators distributed in a laminated mode, wherein the depth regulators are used for controllinga diffraction angle of light reflected by the depth regulators so that the image generated by the image source carries out imaging at a position which has a corresponding depth with human eyes; and the control unit selects the corresponding depth regulator to carry out reflection diffraction imaging on the image according to a color component of the image generated by the image source and depth information. By using the augmented reality display device, through adjusting of the imaging unit, the image from a human eye photopic vision distance to an infinite depth can be generated in a space; true three-dimensional light field display can be realized; and a visual convergence adjustment conflict can be effectively solved and a user experience is improved.

Description

technical field [0001] The invention relates to the technical field of augmented reality display, in particular to an augmented reality display device capable of rapidly switching image depths. Background technique [0002] Augmented reality display is a new display method that superimposes computer-generated virtual information on the real world. According to different application environments, it can combine multimedia, 3D modeling, real-time video display and control, multi-sensor fusion, real-time tracking, scene A number of new technologies, such as fusion, are brought together to provide user experience and bring huge commercial value. [0003] At present, there are related augmented reality products on the market. Under the existing technical conditions, most of these products use the method of projecting virtual images to an infinite distance from the human eye for observation. This can meet the needs of some scenarios, but the long-term Wearing it will cause physio...
