Abstract

The invention belongs to the technical field of intelligent wearing, discloses an eyeball tracking device and eyeball tracking equipment, and the device and the equipment are designed for solving theproblem that an existing eyeball tracking device based on a pupil-corneal reflex method is easily interfered by ambient light. The eyeball tracking device comprises a mounting frame, an eyeball tracking assembly and a light shield. The mounting frame is used for being connected with a head-mounted device. The eyeball tracking assembly and the shading cover are both arranged on the mounting frame,and the shading cover can be arranged between the mounting frame and the face of a user in a surrounding mode. The eyeball tracking equipment comprises a head-mounted device and the eyeball tracking device. The eyeball tracking device and the eyeball tracking equipment are used for realizing eyeball tracking.

Description

Technical field [0001] The present invention relates to the field of smart wear technology, in particular to an eye tracking device and eye tracking equipment. Background technique [0002] Eye tracking, also known as gaze tracking, is a technology that estimates the line of sight and / or gaze point of the eye by measuring eye movement. Among them, 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 above-mentioned three-dimensional vector projected on a certain plane. At present, the optical recording method is widely used: the eye movement of the subject is recorded with a camera or video camera, that is, an eye image reflecting the eye movement is obtained, and then eye features are extracted from the obtained eye image to establish an estimate Model of the line of sight / gaze point. Among them, the eye features may include: pupil position, pupil shape, iris position, iris shape, eyel...
