Abstract

The invention discloses a lip motion capturing method and device and a storage medium. The lip motion capturing method comprises the steps of acquiring a real-time image taken by a camera shooting device, and extracting a real-time face image from the real-time image; inputting the real-time face image into a pre-trained lip average model, and recognizing t lip feature points representing a lip position in the real-time face image; and calculating the motion direction and the motion distance of a lip in the real-time face image according to x, y coordinates of the t lip feature points in the real-time face image. The motion information of the lip in the real-time face image is calculated according to the coordinates of the lip feature points, and real-time capturing for lip motions is achieved.

Description

technical field [0001] The present invention relates to the technical field of computer vision processing, in particular to a lip motion capture method, device and computer-readable storage medium. Background technique [0002] Lip motion capture is a biometric technology for user lip motion recognition based on human facial feature information. At present, the application field of lip motion capture is very wide, and it plays a very important role in many fields such as access control and attendance, identification, etc., and brings great convenience to people's life. For lip motion capture, the general product method is to use deep learning methods to train a classification model of lip features through deep learning, and then use the classification model to judge the features of lips. [0003] However, using deep learning methods to train lip features, the number of lip features depends entirely on the type of lip samples, such as judging mouth opening and closing, then ...
