Mesh Animation Generation Method for Pronunciation Organs

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 movement of a vocal organ, in particular to a method for generating a grid animation of the vocal organ. Background technique [0002] Articulation organ movement reproduction is an important content of articulation organ modeling and pronunciation mechanism research. The grid animation generation method of articulation organs simplifies the complexity of the movement description of articulation organs, thus providing a kind of realizable movement data based on key points The reconstruction method of the articulator movement. It can reconstruct the coordinated movement of the entire vocal organ through the movement of the key points of the vocal organ movement collected from the human body or obtained through mechanism analysis. The results of the research on the pronunciation mechanism, the diagnosis and treatment of the phonation disorder of the vocal organ, and The field of human-computer interact...

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 and motion of the human vocal organs are specific to a specific person; another method is By establishing a biophysical model of the vocal organs, through the organ structure of the vocal organs, especially the muscle structure, analyzing the stress on the organs during pronunciation, and then reconstructing the movement of the vocal organs, using this method to the theoretical level of anatomy and biomechanics The requirements are very high and the amount of calculation is large, so it is not suitable for general applications
