Abstract
The application discloses a lip movement capturing method and device and a storage medium. The method includes: acquiring a real-time image shot by a photographic device and extracting a real-time facial image from the real-time image; inputting the real-time facial image into a pretrained lip average model and recognizing t lip feature points representative of positions of lips in the real-time facial image; and calculating a movement direction and movement distance of the lips in the real-time facial image according to x and y coordinates of the t lip feature points in the real-time facial image. According to the application, movement information of the lips in the real-time facial image is calculated according to the coordinates of the lip feature points to implement real-time capturing of movements of the lips.
