At NAB 2009, we showed our real-time CamTrak. Capturing up to four performers in real-time while tracking the movement of a studio camera. This software enables us to incorporate the studio cameras into our camera system and accurately track its 6 DOF coordinate position to sub-millimeter accuracy. Our software models the studio camera as if it were one of our tracking cameras. We automatically (in Real-Time) calculate the offset from the markers on the studio cameras to its line of sight, establishing perfect alignment of the virtual scene and the studio video scene.
