Next-Generation, High-Accuracy Optical Tracker for Target Acquisition and Cueing

Ascension Technology proposes to develop a fast, six degrees-of-freedom tracker, phasorBIRD, immune to cockpit and helmet scatterers of magnetic/electrical field energy. It will integrate seamlessly with helmet-mounted displays in tactical aircraft,tracked ground vehicles, and combat air operations centers (CAOCs). Design features will enable it to exceed static accuracy and repeatability of the best magnetic trackers while eliminating the need for elaborate alignment and mapping hardware thatsignificantly impacts logistical costs. Development will be based on a research model now returning accuracy of 0.2 mm/0.2¿ RMS. In this project, we will develop a stand-alone system with miniaturized cameras as well as demonstrate feasibility for sunlightoperation and compatibility with NVG systems. We will first develop and test small, operational camera prototypes and second demonstrate that emitter modules can be made compatible with operational scenarios by testing performance in the pressurized cabinof a small aircraft and in a tracked vehicle. Once fully developed, the tracker will overcome performance and applicability limits caused by bulky, obstructive emitters and lens-based cameras that interfere with human motion, cockpit layout, andingress/egress. The military will benefit in that the technology can be evolved to high volume commercial (3D interaction with real-time visualization systems, simulators, procedural trainers, VR gaming etc) as well as helmet-display applications thusamortizing manufacturing costs over large volumes for increased affordability and lowering life-cycle costs.
