Abstract

The invention discloses an eyeball tracking device, a head-mounted device and an eye image acquisition method. The eyeball tracking device includes a light source unit configured to emit a light beamtoward a user's eye; a beam splitter unit configured to be capable of transmitting light of at least a first wave band and reflecting light of a second wave band, wherein the light beams emitted by the light source unit are reflected to the beam splitter unit through the eyes of the user; and an image acquisition unit used for acquiring eye images. By using the eyeball tracking device, the qualityof the acquired eye image can be improved on the basis of not shielding the sight line of the user.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of eye tracking, and in particular, relate to an eye tracking device, a head-mounted device, and an eye image acquisition method. Background technique [0002] With the rapid development of artificial intelligence, machine vision and other fields, eye tracking technology has been widely used. Eye tracking, also known as gaze tracking, is a technology for estimating the line of sight and / or fixation point of the eye by measuring eye movement. Existing eye tracking devices mainly include an illumination unit and an acquisition unit. The light source emitted by the illumination unit is reflected by human eyes and finally imaged on the acquisition unit. [0003] However, when the existing eye tracking device acquires eye images through the acquisition unit, it cannot guarantee to obtain eye images of good quality without blocking the user's line of sight, which seriously affects the user's ...
