Abstract
The application discloses an eyeball movement capturing method, which includes: acquiring a real-time image shot by a photographic device and extracting a real-time facial image; inputting the real-time facial image into a pretrained eyeball mean shape and recognizing n1 orbit feature points and n2 eyeball feature points; and calculating a movement direction and movement distance of an eyeball in the real-time facial image according to x and y coordinates of the (n1+n2) eyeball feature points in the real-time facial image. The application also discloses an electronic device and a computer-readable storage medium. According to the application, movement information of the eyeball in the real-time facial image is calculated according to the coordinates of the eye feature points to implement real-time capturing of an eyeball movement.
