Research On Key Technology For Visual Studio In Prototype System

Virtual Studio System (VSS), combining the Color Key Technology with Graphic Dealing Technology, integrating live screened foreground pictures with the artificial background ones depicted by computer gorgeously, can let true figures interact with virtual background timely, which provides a bright and infinite developing scope for TV making industry.However, VSS developed on the basis of workstation will cost a lot, And comparatively, it will be more reasonable to built VSS based on PCs, which are cheaper, flexible to control, etc. The dissertation, beginning with the analysis of contracture of VSS, will put main efforts on studying the core technologies in original system of multi-PCs style virtual studio.First, the dissertation will study many key technologies of VSS, including the orientating and adjusting of camera, the parameter tracing system of camera, the receiving of motion datum, the plot of virtual scenes, cutting and filling video, the designing of lighting, etc.Next, it will study the accepting and organizing of 3-D datum of VSS, including information of geometry, material properties, pasting picture, and animation. Meanwhile, study the facture process of computer animation.Then, it will study how to accelerate the romancing speed without lowering the quality of pictures or rising of expense, and how to operate the virtual scene spatially. And it will also study the painting of 3d picture, and the real-time romance of true scenes.Finally, it will study the systemic structure of multi-PCs virtual studio, involving function composition, hardware system. The dissertation will project an original system of multi-PCs VSS. It will introduce the original system of VSS, and the functions of every module in scene building system of VSS. And still, from compiling of divided camera playing-script, screening and REC, and post processing, it will study the VSStechnology being put in reality in educational TV programs, and from film head creating, virtual figures, and moving scenes, it will study how to apply VSS technology concretely in educational TV programs.
