Problems solved by technology

[0003] Among the existing articulation organ motion reproduction technologies, one is based on imaging methods, which obtain specific person’s facial features through imaging data collected from the human body, such as optical images, nuclear magnetic resonance images, X-ray images, and ultrasound imaging. The shape and movement of the vocal organs, this method is very expensive, and the complete vocal organ model and its motion process obtained from the image need to go through complex calculations, and the obtained shape an

Abstract

The invention provides a method for generating lattice animation of vocal organs. The method comprises the following steps of defining vocal organ movement key points; generating a two-dimensional lattice of a midsagittal plane of each vocal organ; obtaining texture maps of the vocal organs; performing thin plate spline-based lattice movement calculation. The shape of the midsagittal plane of each vocal organ is calculated according to the positions of the vocal organ movement key points, and the movement condition of the whole vocal organs on the midsagittal planes is directly obtained according to the movement of the vocal organ movement key points, and the method has the advantages of simplifying description parameters for vocal organ movement and reducing the difficulty in making the animation of the vocal organs.

Description

technical field [0001] The invention relates to a technique for reproducing the motion of a vocal organ, in particular to a method for generating a grid animation of a vocal organ. Background technique [0002] Articulation organ motion reproduction is an important content of articulation organ modeling and articulation mechanism research. The mesh animation generation method of articulatory organs simplifies the complexity of articulatory motion description, thus providing an achievable method based on key point motion data Articulatory Motion Reconstruction Method. It can reconstruct the coordinated movement of the entire pronunciation organ through the movement of the key points of the pronunciation organ collected from the human body or through mechanism analysis. The field of human-computer interaction is of great significance. [0003] Among the existing articulation organ motion reproduction technologies, one is based on imaging methods, which obtain specific person...
