Abstract

The invention provides a near-to-eye display device capable of automatically measuring an interpupillary distance and a method. The device comprises a lens unit, a shooting unit, a processing unit and a display unit, wherein the shot image information can be transmitted by the shooting unit to the processing unit, pupil abscissas of a user can be determined by the processing unit according to the received information, and the interpupillary distance of the user can be calculated according to difference of the pupil abscissas of images shot by a left shooting device and a right shooting device. Compared with the prior art, the method can not only be utilized to measure the interpupillary distance of the user, but also can be utilized to measure displacement of a single side pupil of the user deviating from a center position, the eyesight information of the user with asymmetric pupils can be precisely measured, and bases are provided for manually or automatically adjusting an optical system to adapt to the pupil position.

Description

technical field [0001] The present invention relates to the field of near-eye display devices, and more specifically, to a near-eye display device and method capable of automatically measuring interpupillary distance. 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] Near-eye display devices must be measured for interpupillary distance before use. When the user's eyeball po...
