Abstract

The invention discloses a lens adjusting method and a lens adjusting device for head-mounted display equipment, and head-mounted display equipment. The lens adjusting method comprises the steps of making an infrared light source emit infrared light; making an infrared camera acquire an eye image of a current user; determining the current pupillary distance of the current user according to a distance between pupils in the eye image; determining the target position of each lens according to the current pupillary distance, and making two lenses move to corresponding target positions. Through the lens adjusting method, the lens position can be automatically adjusted through detecting the pupillary distance of the user so that the user acquires a clear image, thereby reducing user operations and improving user experience.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display devices, and more particularly, the present invention relates to a lens adjustment method and device for head-mounted display devices and the head-mounted display device. Background technique [0002] At present, the head-mounted display devices on the market basically use a mechanical knob to adjust the distance between the lenses and the distance between the display screens, so that the visual image changes from blurred to clear. This is because the pupillary distance of each user is different. Only by adjusting the lens and display screen to the position suitable for the pupil through the knob can a clearer image be obtained. However, this not only brings some extra operations to the user, but also may take a long time to adjust, which affects user experience. [0003] Therefore, it is very valuable to propose a solution that can automatically, quickly and accurately adjus...
