Research On The Music-Driven Dance Edit Technology And System Application

Creating animation, with or without the use of a computer, has always been a very time-consuming process. The advent of computer-aided animation has allowed computers to perform a great deal of the effort involved in this type of work, especially for tasks suck as animation human characters, dealing with collisions, and sound synchronization. Sounds are generally associated with motion events in the real world, and as a result thereis an intimate linkage between the two. Hence, producing effective animations requires synchronization of sound and motion, which remains an essential, yet difficult,task in animation.With the bringing forward of the Digital Human conception and the growning up of the Frequency Analysis Theory, The requirement that implementing the frequency-motion synchronization design system by Music-Driven Mode has been refered to the research of Digital Art Design domain more imminently. And the national region dance such as Bianzhong Dance give Music-Driven Motion Editing research bran-new ideas and material. The combination of these two not only supply implementing of Music-Driven Motion Edit technology practiced and artistic running foundation, but also a important project of the realization of digital of Bianzhong Dance by Virtual Reality technology, will give contribute to the Digital Art Design region and the innovation of the national dance.The goal of this work is to combine the power of advanced music analysis performed on both MIDI and audio signals with motion editing to simplify and automate the generation of synchronised musical animations. This unified framework will enable animators to try out different combinations of music/sound analysis techniques with familiar motion editing methods without having to acquire a deep understanding of either.The Paper first summarize the characteristic of Music-Driven technology, expound each phase of Frequency Analysis and the idiographic process, and establish the foundation of the implement of Frequency Analysis in MIDI mode. Then,after assaying the Frequency Analysis technology and applications, referring to the MIDI format, advance a triple Frequency Analysis framework based on MIDI analysis, Audio analysisand Music analysis, and output the music/motion script file as the finally result. Afterwards, it depict the characteristic of Bianzhong Dance and the Digital method, and put forward the conception of Motion-Relation based on the Bianzhong Dance grammar. Give the estimation between different motion by Motion-Relation module, and educe the optimization matching. After depiction of the flow and phase result of Frequency Analysis(MIDI) and Motion-Relation(based on Poser),the paper switch to the discussion of how to combine the Frequency flow and Video flow, and make them synchronous. We import the mechanism which make the Frequency flow and Video flow corresponding to each other by Hevner Adjective Circle, at the same time system improve current arithmetic to make them synchronous. Ultimately, by applications of those technology mentioned forward, the paper accomplish a Music-Driven Dance Edit archetypal system, for the purpose of select and edit dance action according to the Bianzhong music, and then simply introduces the architecture, the modules and the design flow of the system.
