The lens unit 122 is disposed on an optical path of image light between the display unit 110 and the beam splitter 121 and may refract the image light output from the display unit 110 . In particular, it is composed of a plano-convex lens that is convex toward the beam splitter 121, so that the image light output from the display unit 110 is refracted by the plano-convex lens and transmitted to the beam splitter 121, so that the display unit 110 It is possible to secure a Field of View (FOV) of 40 degrees or more even without enlarging or enlarging the mirror unit 123 .

It may further include an adjustment unit 400, an external camera unit 500, a sensor unit 600, and a communication unit 700. Hereinafter, the rest of the components of the augmented reality glasses device 10 will be described in detail. do.

The HMD frame 200 is a frame configuration of the augmented reality glasses device 10 that can be worn on the head by the user. The HMD frame 200 may be configured in the form of a helmet or goggles having a frame structure through which light may enter while worn on the head by a user.

The controller 300 may control the operation of the augmented reality glasses device 10 including the optical device 100 to provide augmented reality by mapping image light to the real world seen through the user's field of view.

The IPD adjusting unit 400 may adjust an interpupillary distance (IPD) by adjusting a distance between the pair of optical devices 100 . The controller 300 may control the IPD adjuster 400 to adjust the distance between the pair of optical devices 100 according to the user's IPD adjustment signal or pre-stored IPD adjustment information for the user. That is, when a user directly manipulates a button or moves the optical device 100 by hand to input an IPD control signal, the control unit 300 may control the IPD control unit 400 according to the IPD control signal. Alternatively, the IPD adjusting unit 400 may be automatically controlled according to pre-stored IPD adjusting information.

FIG. 8 is a diagram for explaining the IPD adjustment unit 400 of the augmented reality glasses device 10 including the vision matching type optical device 100 according to an embodiment of the present invention.

By mapping to the real world, camera errors caused by IPD adjustment can be removed.

Since the distance between the pupils is different for each user, in the binocular display type augmented reality glasses device 10 that provides images to both eyes, the distance between the pupils must be easily adjusted to suit the user in order to experience well-focused and clear augmented reality. . However, in the conventional augmented reality glasses, since the camera is located between both eyes, that is, between the pair of optical devices 100, adjusting the IPD changes the relative position of the camera and the optical device 100, resulting in camera error. there was For example, an error correction means or algorithm is added to correct a registration error of an augmented image due to a camera position. However, since the optical device 100 moves when the IPD is adjusted, such an error correction means or algorithm does not work properly. .

On the other hand, in the augmented reality glasses device 10 including the vision matching type optical device 100 according to an embodiment of the present invention, the image input unit 130 is aligned with the display unit 110 within the optical device 100 That is, since the camera is disposed, when the optical device 100 is moved by IPD adjustment, the image input unit 130 moves together, so that an accurate field matching image can be stably obtained.

Here, a method of adjusting the distance between the pair of optical devices 100 by the IPD adjuster 400 may be implemented in various ways, such as using an ultra-precision motor or a rotary damper, based on a rack and pinion method.

Depending on the embodiment, the control unit 300 controls the IPD adjuster 400 according to the pupil position of the user collected by the pupil tracking sensor of the sensor unit 600 to automatically adjust the pupil distance to the user without the user's hands. Distance can be adjusted.

Meanwhile, according to an embodiment, the control unit 300 matches and stores the inter-pupillary distance adjusted by the IPD adjustment unit 400 with user authentication information, and when the user wears the HMD frame 200 and performs user authentication, The interpupillary distance suitable for the user may be automatically adjusted by controlling the IPD adjuster 400 according to pre-stored IPD adjustment information for the user. Here, the IPD adjustment information matched with the user authentication information and stored may be a distance adjusted according to the user's IPD adjustment signal. At this time, user authentication may use an iris recognition sensor included in the sensor unit 600 .

The communication unit 700 is installed on one side of the wearable augmented reality device 10 and can transmit and receive various signals and data to and from other wearable augmented reality devices 10 or servers. Here, the network used by the communication unit 700 is a wired network or a mobile communication network such as a Local Area Network (LAN), a Wide Area Network (WAN), or a Value Added Network (VAN). radio communication network), satellite communication network, Bluetooth, Wibro (Wireless Broadband Internet), HSDPA (High Speed Downlink Packet Access), LTE (Long Term Evolution), 3/4/5/6G (3/4/5/ It can be implemented in all types of wireless networks such as 6th Generation Mobile Telecommunication).
