Eye tracking device and eye tracking method applied to video glasses and video glasses

A pair of video glasses, comprising an eye tracking device, wherein the eye tracking device comprises a light source component, a reflection component, an image sensor component and a main control component;

• wherein the light source component is configured to emit invisible light to an eyeball;
• wherein the reflection component is configured to reflect the invisible light reflected by the eyeball;
• wherein the image sensor component is configured to generate an image of the eyeball based on the invisible light reflected by the reflection component;
• wherein the main control component is coupled to the image sensor component and is configured to acquire a gaze direction based on the image of the eyeball;
• wherein the eye tracking device further comprises a calibration light source component, wherein the calibration light source component is configured to emit invisible light to the reflection component;
• wherein the reflection component is configured to reflect the invisible light emitted by the calibration light source, the image sensor component is configured to generate a calibration light source image, and the main control component is configured to acquire a calibration matrix corresponding to the image sensor component based on the calibration light source image;
• wherein the main control component is configured to acquire the gaze direction based on the image of the eyeball and the calibration matrix.
