Design And Implementation Of TV Program Production Management System Based On Virtual Reality

If the current TV program production is still in accordance with traditional methods,it will be difficult to attract the attention of the audience and drive the audience's emotions.The virtual reality technology has got rid of this dilemma.According to the psychological needs of TV viewers,the TV scene is stereoscopic and real,so that the audience can feel the situation to be transmitted more vividly.Based on this,in order to improve the current level of domestic TV program production and the efficiency of work,this paper designs and implements a set of the most representative virtual reality TV program production system.This paper first summarizes the research and development experience of TV program production system based on virtual reality technology through literature analysis method to provide guidance and reference for the research and development of this system.Combined with the TV program production process and system user requirements,the UML use case method is used to analyze the system's functional requirements,and the system's functional architecture is determined.The camera position management function,on-site lighting management function,virtual studio function,and TV audio equipment management function are designed.Six function modules for image editing management and production management functions.Considering the application of virtual reality technology to the TV program production management system,the core business is to realize the synthesis of virtual scenes and the production of virtual TV programs through the design of virtual reality scene synthesis algorithms and key processes.The key algorithm and process flow,such as the map algorithm,the real-time acquisition and storage of camera data,and the loading of the image into the 3D virtual scene are discussed in detail.The color key-based mapping algorithm obtains a sequence image of each frame from the captured camera image data,and thresholds the sequence image to obtain a binary black and white image,and then uses a morphological algorithm to threshold the image.The edges of the image are processed to achieve accurate mapping and perfect integration with the new image.The system network framework,sensor operation process,data storage security management and other content are designed accordingly to improve the system process structure;in the system implementation part,the representative interface of the final implementation is given.Finally,the system istested according to the user's normal operation and actual needs.By observing the reflection of the system to ensure the normal operation of the system application,the test results show that the system meets the original design requirements.Using virtual reality technology to create virtual studio function modules,the virtual programming of TV program production is realized.Virtual studio is a product that combines virtual reality technology with color key matting technology.This is different from the traditional color key matting technology in that it introduces information exchange technology.By using camera tracking technology,the real camera motion parameters are acquired and compared with the motion parameters of virtual cameras,so that the real and virtual cameras can be synchronized.In this way,the background picture captured by virtual camera and the person captured by real camera can be combined to form a perfect picture through color key matting technology.The virtual reality-based TV program production management system can realize the realistic virtual effect by creating a virtual three-dimensional model and realizing the perfect combination of the target image and the virtual three-dimensional model on the basis of the map,and applying it to the actual TV.In the interface production management work,it can effectively improve the work efficiency of TV program production and bring greater economic benefits to TV program production.
