Abstract

The invention discloses a device and a method for realizing augmented reality. The device includes a display chip, a lens assembly, a beam splitter, and a Fresnel lens group. The display chip is used for displaying an image. The lens assembly is positioned on one side of the display chip, and is used for converging light emitted from the display chip to get converged emergent light. The beam splitter is positioned on the emergent light side of the lens assembly and at a first preset angle relative to the plane where the display chip is, and is used for transmitting one part of the emergent light out of the beam splitter to get first transmitted light and vertically reflecting the other part of the emergent light to the Fresnel lens group. The Fresnel lens group is positioned at a second preset angle relative to the beam splitter, and is used for reflecting the light hitting the Fresnel lens group back to the beam splitter and transmitting the light out of the beam splitter to get second transmitted light. A first Fresnel lens and a second Fresnel lens are Fresnel lenses with complementary surface types. The first transmitted light and the second transmitted light are used to form a stereo scene of augmented reality. The cost of the augmented reality equipment glasses is reduced.

Description

technical field [0001] The present invention relates to the field of augmented reality, in particular, to a device and method for realizing augmented reality. Background technique [0002] Augmented reality technology is a new electronic device, which is used to project images of information such as image text models into human eyes, so that people can observe virtual information at the same time without affecting the viewing of real scenes, achieving virtual and real fusion experience. [0003] Similar technical solutions include google glass, hololens, mata2, Epson bt200. Their products all use different optical display methods, but these different optical display methods have the following disadvantages: [0004] Both Google glass and Epson bt200 use glass prism optical display modules, which are heavy and designed with a small viewing angle, making the wearing experience poor; [0005] The display module of Hololens is expensive and has poor environmental adaptability...
