In this paper, we present a robust infrared optical 3D position tracking for wide area indoor environments up to 30m. The system consists of two shutter-synchronized cameras that track multiple targets, which are equipped with infrared light emitting diodes. Our system is able to learn targets as well as to perform extrinsic calibration and 3D position tracking in unconstrained environments, which exhibit occlusions and static as well as locomotive interfering infrared lights. Tracking targets can directly be used for calibration which minimizes the amount of necessary hardware. With the presented approach, limitations of state-of-the-art tracking systems in terms of volume coverage, sensitivity during training and calibration, setup complexity and hardware costs can be minimized. Preliminary results indicate interactive tracking with minimal jitter < 0.0675mm and 3D point accuracy of < 9.22mm throughout the entire tracking volume up to 30m.
