O aprimoramento de um software de estúdio virtual por meio de técnicas de matting digital e registro de objetos virtuais

A virtual studio system can use technologies as augmented reality and digital matting to decrease production costs at the same time it provides the same resources of a conventional studio. With this, it’s possible for the current studios, with low cost and using conventional devices, to create productions with greater image quality and effects. Some difficulties are recurrent in virtual studio applications that use augmented reality and digital matting. The virtual objects registration in augmented reality techniques suffer from problems caused by optical distortions in the camera, errors in the marker tracking system, lack of calibration on the equipments or on the environment (lighting, for example), or even by delays in the virtual objects display. On the other hand, the digital matting’s main problem is the real-time execution to preview the scene, which must have optimized processing speed at the same time while maintain the best image quality possible. Taking the given context into consideration, this work aims to give continuity to a virtual studio system called ARStudio, by enhancing digital matting, virtual objects registration and introducing a segmentation based on depth map, yet adding better control over functionalities previously implemented

ARSTUDIO: estúdio virtual para produção de conteúdos audiovisuais em realidade aumentada para a TV Digital

“Virtual Studio” is a system developed for the creation of virtual sets, as well as any threedimensional virtual objects that can be digitally integrated to the scenes captured on a real television studio. Through techniques such as chroma-key, computer graphics , augmented reality and virtual reality is possible flexibility in producing content for digital TV, reduce cost and meet 12.485/2011 law, the Brazilian “Law of Pay TV”, which has among its objectives “to increase the production and circulation of diverse and quality Brazilian audiovisual content, generating jobs, income, royalties, professionalism and strengthening of national culture” (ANCINE , Brazilian Nacional Cinema Agency ). Based on this background, an overview of the benefits of using the technologies mentioned for the production of content for digital television is presented. This work involves the development of a system of Interactive Virtual Studio called ARSTUDIO per team of researchers from the Posgraduate Program in Digital Television: Information and Knowledge at UNESP, São Paulo State University in Bauru, State of São Paulo, Brazil.
