虚拟摄影棚资源制作系统研究与实现
|
摘要
虚拟摄影棚技术主要用于电视节目资源制作这个领域,它是将摄像机拍摄的现场画面作为前景,实时地与计算机生成的三维图形进行合成,从而生成新的电视节目系统。当前所使用的虚拟摄影棚三维系统,价格在50-200万美元左右,二维的则在十几万美元左右,这么昂贵的制作代价,使很多电视节目制作单位难以承受。因此,搭建一套低成本虚拟摄影棚,但能够高效率的制作出高质量电视节目,是符合观众对资源节目需要。
本文是基于华中师范大学教育信息技术工程中心的低成本虚拟摄影棚平台项目,为该项目提供串口与硬件控制技术、虚拟背景显示技术以及资源管理技术。为了能够使这套系统被广泛的安装与使用,本文还对虚拟摄影棚系统设计做了详细的绍,这可以使电视节目制作单位根据实际需要,搭建虚拟摄影棚系统。该虚拟摄影棚系统主要考虑在较低的价位上,实现较高的性能。因此,在系统整体设计上是采用桌面控制软件实现硬件控制,在软件设计上选取常用的操作,使用户界面尽可能简便,这就降低了虚拟摄影棚系统对操作人员的要求。在虚拟背景显示方面,目前绝大多数虚拟摄影棚是通过硬件输入设备比如DVD为抠像机提供虚拟场景,这增加了虚拟摄影棚成本,同时对背景的操作比较繁琐,而本系统通过开发虚拟背景显示软件,可以方便快捷的提供虚拟场景。为了使该系统能够更好的应用于教育领域,特意开发了虚拟前景显示模块,它可以为虚拟摄影棚提供一路PPT前景信号,以供系统操作人员使用。此外虚拟摄影棚系统还研究与实现了资源管理子系统,它可以对资源素材进行科学化的管理,提高资源管理的效率。
Virtual studio technology is mainly used for television programs Authoring. It enables the foreground offered by camerasthree-dimensional and virtual scene generated by computer real-time synthesize. The current price of three-dimensional virtual studio systemis about 500000 dollar, and two-dimensional is more than 100000 dollar. The production costs are too high to bear for many programs units. Therefore,building a set of low-cost virtual studio which efficiently authors high-quality television programs could meet the demand of the audience for resources programs..
This article is based on the low-cost virtual studio platform project of Engineering Research Center for Education Information Technologies in the Center China Normal University, and provides for the project serial port and hareware control technology, virtual background display technology as well as resource management technology. At the same time,this article detailly introduce the desigh of virtual studio system . This allows the units of television programs authoring to set up a virtual studio system,according to the actual needs. The virtual studio system is mainly to consider a lower price and higher performance . The overall design of the virtual studio system is acheived through desktop software to control hardware. The software design is used to select the common operation, and makes the user interface simple as far as possible, which reduces the requirements of the operator. At present,the vast majority of virtual studio provided the virtual scenes with hardware input device such as DVD . This increases the cost of the virtual studio, at the same time the Background operations are more complicated. The system develope software of virtual background display, which can provide convenient and efficient virtual scene. In order to enable the system to apply for the field of education, this software specifically increase the virtual display of the prospects, which can provide a PPT signal.The system operators could access signal as foreground. In addition to the virtual studio system developed a resource management subsystem, which can achieve the scientific management and improve the efficiency of resource management.
