Body Calibration

After setting up the tracking system, i.e. after camera mounting and cabeling, the exact position and orientation (“external orientation”) of each camera has to be determined. This is done by a simple calibration procedure that takes not more than five minutes. This “room calibration” process uses an angle with four markers, which defines the coordinate system, and a stick with two markers (“wand”) , which is moved in the tracking volume. Room calibration software and hardware are included in the DTrack package.
