Abstract

The invention discloses an eyeball tracking method and device, and the method comprises the steps: obtaining the eye feature information of a first eye and the eye feature information of a second eyeof a user; obtaining a first sight line by utilizing the eye feature information of the first eye and the calibration coefficient of the first eye according to a first preset rule, and obtaining a second sight line by utilizing the eye feature information of the second eye and the calibration coefficient of the second eye; according to the first sight line and the second sight line, gaze depth information of the user is obtained, sight lines emitted by different eyeballs of the user are independently calibrated and tracked, a user gaze point comprising the depth information can be determined,and accurate tracking of the user gaze point in the three-dimensional space is achieved.

Description

technical field [0001] The present application relates to the technical field of eye tracking, in particular to an eye tracking method and device. Background technique [0002] With the development of technology, especially the development of virtual reality technology, users can control electronic devices through eye movements. This control method is generally implemented by using eye-tracking technology to track the user's gaze point, and realize various control operations according to the tracking results. [0003] However, the currently commonly used eye tracking method can only guarantee the accuracy of the user's actual gaze point recognition when the user is gazing at objects at different positions in the two-dimensional plane direction, that is, it can only accurately describe the correspondence between the gaze point and the eyeball position in the plane direction relation. When the user is looking at two objects with the same two-dimensional position but differen...
