Abstract: Simple Actor Tracking for Virtual TV Studios Using a Photonic Mixing Device

Jens Herder, Michael Wilke, Julia Heimbach, Sebastian Gbel, and Dionysios Marinos. Simple Actor Tracking for Virtual TV Studios Using a Photonic Mixing Device, 12th International Conference on Human and Computer, Hamamatsu/Aizu-Wakamatsu/Duesseldorf, December, 2009.

Virtual TV studios use actor tracking systems for resolving the occlusion of computer graphics and studio camera image. The actor tracking delivers the distance between actor and studio camera. We deploy a photonic mixing device, which captures a depth map and a luminance image at low resolution. The renderer engines gets one depth value per actor using the OSC protocol. We describe the actor recognition algorithm based on the luminance image and the depth value calculation. We discuss technical issues like noise and calibration.
