Eyeball movement capturing method and device, and storage medium

An eyeball movement capturing method, applied to an electronic device and comprising:

• a real-time facial image acquisition step:
• acquiring a real-time image shot by a photographic device and extracting a real-time facial image from the real-time image by use of a face recognition algorithm;
• a feature point recognition step:
• inputting the real-time facial image into a pretrained eye mean shape and recognizing n1 orbit feature points and n2 eyeball feature points representative of an eye position in the real-time facial image by use of the eye mean shape;
• and
• an eyeball position calculation step:
• 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 orbit feature points and n2 eyeball feature points in the real-time facial image, wherein the eyeball position calculation step comprises:
• calculating a center coordinate of an orbit in the real-time facial image according to the x and y coordinates of the n1 orbit feature points;
• and
• calculating a positional relationship between a center of the orbit and each eyeball feature point to judge the movement direction and movement distance of the eyeball.

A non-transitory computer-readable storage medium, comprising an eyeball movement capturing program, the eyeball movement capturing program being executed by a processor to implement the following steps of:

• a real-time facial image acquisition step:
