The Study Of Intelligent Stage Technology Based On Data-driven

Modern intelligent stage adopts brand new systematic design methods and ideas andintegrates multimedia technology, mechanical control technology, computer science andsimulation technology into the stage design and operation. Comprehensive application ofvarious technologies does not only expand the stage presentation effect of space-time, butalso build a immersive effect as well as put forward higher requirements on the choreography,stage machinery control, stage performance collaboration and so on.This research studies the following technical difficulties including numerical stagemodeling, stage motion data processing and error control, stage data standardizationagreement, virtual scene simulation based on the data and optimization of multimediadynamic stage and choreography process. The study process and research results are asfollows:(1)Perfect the digital stage modeling process, and put forward the concept of thepresentation layer and data layer of the model. The study embeds data element in thepresentation layer of the3d stage to make the stage model, which is based on data creation,meet the needs of stage editing and visual simulation, and the stage data processing andstandardization building of stage data;(2)The study puts forward the extraction and processing method of stage data. Itcombines the mechanical stage performance indicators, adopts linear function based on theparabola fitting to optimize the stage data and reduce the errors in motion parameters ofvirtual stage and mechanical stage. By adding virtual stage animation production based onstage machinery operation data, it is designed to build the bidirectional data flow betweenvirtual world and the reality;(3) This paper is designed to complete the stage data coordination by defining stage datastandard protocol. The definition of standard data protocol is based on the position andposture of the3d objects. In accordance with data standard protocols, we should set up stagedata coordination mechanism and complete the data sharing of each production link of thestage(4) This study chooses to use real-time rendering3d simulation engine to create virtualscenes. The establishment of the virtual scenes covers simulations of mechanical movementon the stage, stage background video effects, the effects of stage lights, camera placement,broadcast control and so on. It completes the preview of production results and the overall effect of each link on the stage in the virtual scene;(5) The research results takes the data as the core, simulation as the means, and providessupport to each link of the stage production, and meets the goals of optimizing productionprocess, decreasing turnaround times, speeding up the production and standardizes andprocessizes the complex stage production of multimedia dynamic stage.The research results have been applied in the composition and production of CCTVSpring Festival galas and Lantern Festival galas from2011to2014.
