For many years, Shotoku has provided leading broadcasters with a range of VR tracking systems from simple 2D pan and tilt heads to full-sized 3D systems based on pedestals, cranes, and jibs. These systems provide precise, reliable, and easy-to-use hardware-based VR tracking data, and are available on Shotoku`s range of manual or robotic camera support systems. Free-d, originally developed by engineers at BBC Research and Development, is the latest addition to the range but differs fundamentally in that it is free of encoder-based physical tracking.
By utilizing simple external reference markers easily mounted to the studio ceiling or within the lighting grid, Free-d² -the next generation of Free-d, is able to track cameras of any type, on any new or existing camera support syste, including Steadicam or even hand-held operations. The 8-axis full 3D tracking system is “absolute”, meaning it is fully referenced at all times, with no buildup of small errors due to drift and no need for a “home” position or re-referencing.
The unique system consists of a small upward-facing tracking camera providing a view of the studio ceiling and referencing corresponding reference markers. Lens data is combined with the video image and presented to the Free-d² processor which precisely calculates the camera`s 3D position and provides industry-standard, frame-synchronized tracking data for any graphic engine.
Once a studio is calibrated it will generally never be necessary to re-calibrate ever again.
