Embodiment approach

[0100] Optionally, in another embodiment of the present invention, an implementation of the step S303 includes: selecting a plurality of different types of objects whose locations are far apart from the database according to the location information of the object. The object mentioned above is used as the calibration position point.

[0101] Wherein, the type of the object is obtained by identifying the object in the real scene.

[0102] It should be noted that the type of the object refers to the category to which the object belongs. Specifically, it may be obtained while performing step S301 to identify the object in the real scene and obtain the position information of the determined object. Of course, the display scene can be recognized separately to obtain the category of the object. Specifically, the type of the object in the picture may be identified through a neural network model.

[0103] In order to make the calibration of the eye tracking device more accurate, th...

Abstract

The invention discloses an eyeball tracking calibration method. The method comprises the steps of obtaining a real scene in front of the eyes of a user; determining a calibration position point in thereal scene; acquiring feature information of a user, wherein the feature information of the user is feature information when the user watches the calibration position point; and calibrating the eyeball tracking device according to the feature information and the information of the calibration position point. According to the invention, the real scene in front of the eyes of the user is acquired,and the position point for calibration is determined from the real scene, so that the whole calibration method is not limited by factors such as the size of a screen, and therefore, the method is veryflexible, can well adapt to different users, and ensures that an accurate calibration result is obtained. The invention further discloses an eyeball tracking calibration device and system corresponding to the calibration method.

Description

technical field [0001] The present invention relates to eye tracking technology, in particular to an eye tracking calibration method, device and system. Background technique [0002] With the development of human-computer interaction technology, eye tracking technology has received extensive attention. Eye tracking technology is a method that uses eye movement measurement equipment to capture user eye images at the millisecond level, generally by analyzing the relative positions of features such as pupil contour, iris contour, pupil center, iris center, and reflection points of external light sources on the cornea, as well as their relative positions. Detect eye movement by the capacitance value between the eyeball and the capacitor plate, or place electrodes on the bridge of the nose, forehead, ear or earlobe, detect eye movement through the detected myoelectric signal pattern, and estimate the user's line of sight direction or line of sight point technology. Human-comput...
