Virtual Studio & Augmented Reality Tracking
Virtually any studio you imagine
More and more broadcasters are using virtual set technology for productions such as news, magazines and sport shows. Even though virtual studios are extremely flexible and cost effective, still today, a fool-proof and reliable tracking system is key to a successful deployment.
Camera tracking is the technology that measure exact camera position in space.This camera position data (inlcuding focus and zoom posiition) is send in sync with each video frame to a virtual studio render engine. The virtual studio rendering engine uses it at his turn to render a virtual set from the same viewing angel as the camera’s position. Matching both foreground and background.
Existing tracking systems use different kinds of technology including image recognition, infra-red or sonar – although some of these technologies are extreme flexible (think handheld or steadicam operation) they pose a real challenge when it comes to instalation, calibration and and maintenance.
Direct lens readout
Many virtual studio systems rely on external lens-encoders to measure zoom and focus position. Although FX-Motion offers such lens-encoders (mainly for use with older analog lenses), it is often a source of problems. As standard on all FX-Motion VR-One products digital (serial) read-out of lenses is provided. This gives also ‘absolute’ readout on lenses and provides integral tracking data at all moments.
Augemented Reality
Augemented reality – placing virtual 3D object as overlay on a video output – has been making lot of headway recently. Imagine the possibility in news or current event programming. Your hosts and interviewees commenting on a actual 3D model of a current event or product.
Precise measurement
Our tracking sensors measure the actual physical position of the camera. Unlike other robotic systems, who measure the robotics motor position, we measure the actual position after mechanical parts as motors, belts and gears etc. This results in a more precise and reliable measurement.
Absolute encoding
FX-Motion’ tracking system uses what is called ‘absolute’ tracking. This means that its position is known a fraction after powering up the equipment. The system needs not to move to a ‘home’ or ‘zero’ position to reset its position. Also, the virtual and real world will always match. Re-Powering or moving the equipment will give you an exact and immediate calibrated virtual studio.
