Abstract

The present invention provides a near-eye display device that automatically adjusts the optical system. The near-eye display device includes an optical system, a camera unit, a processing unit, and a motion unit. The camera unit and the motion unit are electrically connected to the processing unit. connected, the optical system includes a lens unit and a display unit, the camera unit includes a camera device with a fixed focal length and orientation, and the camera device includes a left camera device and a right camera device. Compared with the prior art, the present invention adopts the method of separately measuring and adjusting the coordinate position of the unilateral pupil, which can not only measure the user's interpupillary distance, but also measure the displacement of the user's unilateral pupil from the central position and adjust the corresponding position separately according to the measurement result. The side optical system makes the measurement and adjustment more accurate, ensures a better display effect, and avoids possible deviations caused by only measuring the interpupillary distance to adjust.

Description

technical field [0001] The invention relates to the field of near-eye display devices, and more specifically, to a near-eye display device that automatically adjusts an optical system. Background technique [0002] Near-eye display devices include head-mounted displays (HMDs) that can directly project images into the eyes of observers, and such near-eye display devices are currently commonly used in the field of virtual reality (VR) or augmented reality (AR). Under normal circumstances, the display screen of the near-eye display device is less than ten centimeters away from the user's eyeball. Through special optical processing, the near-eye display device can clearly project the image on the human retina, presenting a virtual large-format image in front of the user's eyes. , and thus be used in virtual or augmented reality. [0003] The near-eye display device must undergo pupillary distance measurement and optical system adjustment before use. When the user's eyeball pos...
