Embodiment 1

[0040] Eye tracking, also known as gaze tracking, is the technique of estimating the line of sight and / or gaze of the eye by measuring eye movement. Wherein, the line of sight can be understood as a three-dimensional vector, and the gaze point can be understood as the two-dimensional coordinates of the projection of the three-dimensional vector on a certain plane.

[0041] In this embodiment, the tracking of eyeballs can be realized by using an optical recording method. The principle of the optical recording method is to use a camera or a video camera to record the eye movement of the subject, that is, to obtain an eye image that can reflect the eye movement, and extract eye features from the acquired eye image to establish a line of sight / fixation point estimation model. Wherein, the eye features may include: pupil position, pupil shape, iris position, iris shape, eyelid position, eye corner position, spot position (or Purchin's spot), etc.

Abstract

The embodiment of the invention discloses a method and device for detecting an eye sight line, equipment and a storage medium. The method includes the steps that under single-eye vision, sight line calibration coefficients of two eyes of a user are obtained separately and comprise the left eye sight line calibration coefficient and the right eye sight line calibration coefficient; under two-eye vision, according to the vision calibration coefficients, two-eye sight line data of the user is obtained. According to the method for detecting the eye sight line, an eyeball tracking module is used for detecting the eye sight line of the user, so that the accuracy of detecting the eye sight line is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of line of sight detection, and in particular, to a method, device, equipment, and storage medium for detecting eye sight. Background technique [0002] Because each person's eyes have different physical characteristics, even when the line of sight is looking in the same direction, the characteristics of the eyes are different. In order to obtain the user's gaze direction, it is first necessary to determine the relationship between certain eye features of the specific user and the gaze direction, so that the user's gaze direction can be obtained through this relationship in the subsequent process. This relationship is called the line-of-sight calibration coefficient, and can also be called the line-of-sight calibration parameter. [0003] In the prior art, conventional methods are usually used to obtain the sight calibration coefficients, that is, to obtain the calibration coefficients...
