Abstract

The invention provides a method and device for acquiring a facial expression of a 3D face model and a storage device. The method comprises the steps of acquiring a 3D face model; acquiring a motion trajectory of a facial feature point by using an RGBD image sequence; and mapping the motion trajectory of the facial feature point to the 3D face model so as to enable a motion trajectory of a facial feature point of the 3D face model to be matched with the acquired motion trajectory of the facial feature point. The device comprises a processor, wherein the processor implements the method. The storage device stores program data which can be executed to implement the above method. The facial expression information acquired according to the invention is more comprehensive and accurate, so that the 3D face model can be enabled to reflect the facial expression of the human face more vividly.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and storage device for acquiring facial expressions of a 3D facial model. Background technique [0002] An RGBD image is obtained by shooting a scene with an RGBD camera. It refers to an image in which depth information and color information are fused. Each image element has an associated color value and an associated depth value. The depth value represents the distance from the image sensor to the scene. distance from the surface of the object. [0003] Expressions are the external manifestations of emotions and emotions. According to the basic emotion model, expressions can be divided into six categories: anger, disgust, fear, happiness, sadness, and surprise. Facial expression recognition has always been of great research significance, and has huge market value in many fields such as human-computer interaction, public safety, and intelligent ...
