Description

A kind of AR glasses

Technical field:

The utility model relates to AR glasses, which is a device capable of playing digital video images, and can be applied in the medical field, teaching, daily electronic entertainment and the like.

Background technique:

AR glasses can superimpose virtual content with the real world, enabling a sensory experience beyond reality. The biggest advantage of AR glasses is that it does not deprive users of their mobility and can freely interact with the real world. It is a mobile computing platform connected to the real world.

There is a problem with the current AR glasses. The AR glasses only have one image signal input port and an image processing chip. Display and right-eye micro-display, the disadvantage of this method is: the existing VR/AR glasses (single-channel) in the market, when processing 3D image signals, one 3D image signal is cut into two-channel signals and then respectively Send it to the left and right eyes of people, which will greatly reduce the definition of the image quality. For example, the original 1920*1080 resolution will be cut into two 960*1080 image quality, which reduces the definition of the 3D image. The 3D stereoscopic image of this kind of AR glasses is different from the image actually seen by the human eye because it imitates the human left eye and right eye to watch the foreign object at the same time.

Invention content:

The purpose of the utility model is to provide a kind of AR glasses, solve the problem that the external image signal input of the AR glasses in the prior art is processed by an image processing chip and then sent to the left-eye microdisplay and the right-eye microdisplay for display. When using a 3D image signal, one channel of 3D image signal is cut into two channels and sent to the left eye and right eye of the person respectively, resulting in a significant reduction in the definition of the picture quality, and there is a certain difference between the 3D stereoscopic image and the image actually seen by the human eye. technical problem.

The above-mentioned spectacle frame housing is connected to a head-mounted device for wearing.

Compared with the prior art, the utility model has the following advantages:

(1) The utility model has the advantages of: using the left-eye image processing chip and the right-eye image processing chip, the left-eye image signal is processed by the left-eye image processing chip and input to the left-eye micro-display for playback; the right-eye image signal is passed through the right-eye image The processing chip processes the input and plays it on the right-eye micro-display, forming a fused 3D stereoscopic image in the human brain, which imitates the human left eye and right eye to watch foreign objects at the same time to synthesize a 3D image, which is more realistic and natural without loss of image quality. Higher resolution.

(2) Other advantages of the present utility model will be described in detail in the embodiment part.
