The BBC’s Virtual Studiotechnology was used to enable realtime composition of the 3D rendered graphics with live camera feeds. Each studio camera has a dedicated render PC to render the virtual scene from that camera’s perspective. To know what a studio camera’s perspective is, each camera is fitted with a second ‘Free-D’ camera which points towards the ceiling. On the ceiling are reflective, circular bar codes. The 3-D camera data is fed to a computer system that identifies the targets on the ceiling and calculates that camera’s position and orientation, 50 times a second. Series 4 adopted vinten tracking peds instead of FREE-D as an alternative approach.

November 4th, 2009
A sample program of NyARToolkit Application on Google Android Emulator. Marker detection part is mostly same as original NyARToolkit (just a few changes are applied).
Video image is sent by Java program which uses socket connection to the emulator because camera device emulation has not been implemented on Android SDK.
The archive includes archive of Eclipse project and demo program to send images that taken by camera to the emulator.
1. Android SDK and Eclipse plugin is required to try it on Eclipse. http://code.google.com/android/
2. Reffered to “Live Camera Previews in Android” by Tom Gibara that is the idea of sending images to emulator. http://www.tomgibara.com/android/camera-source
Indoor – Outdoor panorama tracking
September 26th, 2009Panorama tracking (in real-time)
These videos shows a new approach to create panoramas from live camera feed on mobile phones. Users can literally paint the panorama by rotating the mobile phone. The videos starts with how panoramas is created and then shows two example applications for what can be done with this technique.
Creating an indoor panorama tracking
This video a new technique for real-time creating of panoramic images. The images are 2048×512 in size and can also be used for robust AR tracking.
