The Research Of Musical-light Show Scheme Design System

The system for design of music-light show scheme is the inevitable result of thepopularity of music-light show. Whether it is the stage music-light show, or a largeoutdoor music-light show, both of them are to bring the dual shocking effect ofauditory and visual to people through a perfect combination of dazzling lights andbeautiful music. The conventional method of manual editing performing programs cannot meet the public’s aesthetic changes, and time-consuming. How to design a set ofscheme design-system for music-light show which can simulate human designer hasbecome a major research topic in this field.The scheme design-system for music-light show this paper developed is the newexploration and research based on early research conducted by the research group. Thepurpose is to architecture-optimization and transformation. It has a very importantpractical significance for the application of the system. The main contents are asfollows:First of all, for the non-standardized handling problems of original input/output ofmusic-light show control system (music information and lighting-control data), thispaper researchs the methods of extraction and representation characteristic elements ofmusic emotion information and lighting control information by using a specific methodfor the represent of the control input/output.In the second place, for the "Bottleneck" of traditional ES which is knowledgeacquisition, this paper uses an efficient and comprehensive semi-automatic knowledgeacquisition method which uses traditional experts’ input and imitating examples to getshallow knowledge and uses automatic generation method based on multi-agentbehavior model to get deep knowledge. This method can improve the speed andcontent in building a knowledge base greatly and enhance the usefulness of the systemin terms of knowledge base.Then, for the problem of long-time searching and high error rate caused bydiversity of music-light show scenes in actual application of expert design systemwhich is deployed by a set of knowledge base, this paper uses a kind of expert designsystem which can replace knowledge base according to the type of scene to achieve therapidly designing in different scene layouts.Finally, due to the uncertainty of the design systems which design system for music-light show belongs to, this paper uses production expert system based on theuncertainty reasoning to study its inference engine, and chooses a suitable expertsystem language to develop the system, so that the system can generate high-precisionand high-moderation plan automatically depending on different music and lightinglayout by music emotion characteristics and lighting control data.
