One of the most relevant aspects to obtain a good sense of presence on stage is the capability of the actors to interact, in real time, with the virtual world. Thus, the audience has the feeling of the talents being present in a place where they are not.

In addition, our system allows the production team to remotely follow the production stage and allows content refinements to be carried out quickly through tools, usually used in the post-production stage, that are integrated into the system.Ī virtual TV set combines images from the real world with a virtual environment in order to obtain images that give the impression of the real elements, such as actors or physical objects, being present in a computer-generated scene.

In this paper, we present a low-cost virtual studio called ARStudio that offers a set of functionalities similar to those of professional virtual studios. In addition, if the generated content can be quickly refined and made available to all the staff still in the production stage, the post-production stage can be considerably simplified. Costs can also be avoided if part of the production team can follow along with certain retakes or even the entire production stage remotely.
This can make production more expensive if there is a need to recruit the actors again and reassemble the infrastructure. Such a problem, in the traditional production pipeline, can be identified only in the post-production stage. This approach can cause problems in situations such as ones where an actor acts alongside virtual characters, due to the lack of precise reference for gaze direction, for example. In a traditional production pipeline, virtual elements are inserted only in the post-production stage, and consequently, these elements are only visualized after every editing process is finalized.

Most require high-end PC systems, equipped with broadcast-standard video capture and output cards.įilm, television, and Internet productions have generated content that combines real and virtual elements in the same scene.
Circular studio software#
There are a range of software packages available commercially for the real-time rendering of graphics for mixed reality / virtual studio production. A potential problem with the use of such systems is that by the very nature of the close interaction between presenter and object, there is a risk of the presenter covering the marker, or placing a hand into the space that the virtual object should occupy. Similar systems have been used for hand-held augmented reality using a PC and web-cam, although for broadcast use the systems need to satisfy the high frame-rate and robustness requirements for TV. An example of the use of an image-based marker tracking system for TV production is shown in Figure 4. This allows a presenter to pick up a virtual object, and can provide an interesting way to interact with such objects. There are applications where it is useful to be able to attach virtual graphics to small physical objects rather than fixing them in the world reference frame. Results from this project have already been applied commercially in sports applications, where lines on a football or rugby pitch can be automatically identified and tracked. One example of such work is the MATRIS project. A current topic of active research is the development of tracking systems that can use naturally- occurring features in the scene.
These systems all rely on some form of sensors or special markers in the environment in which the system is being used. Further discussion of other commercially-available tracking systems may be found in Wojdala. A small upward-looking monochrome camera surrounded by a ring of LEDs is mounted on each studio camera to be tracked (Figure 3). An example of such a system is the BBC-developed free-d system, which uses circular retro-reflective barcoded markers on the studio ceiling ( Figure 2). Such systems were first developed for head-mounted augmented reality using active beacons, but have been developed to be suitable for large TV studios. By analyzing the image, the pose of the camera can be computed. The camera views markers, patterns or other easily identifiable features in the studio, whose 3D coordinates are known.
“inside out” tracking system uses images from either the TV camera itself, or an additional camera fixed to the camera being tracked.
