The IS-1200 product family, based on advanced image processing and sensor fusion techniques, is the most advanced and accurate motion tracking product that InterSense offers. Initially offered as a vision-inertial self tracking system, the IS-1200 VisTracker is designed to meet the most demanding tracking requirements dictated by mobile, augmented reality applications. The InertiaCam core consists of six MEMS inertial sensors with an integral "smart camera" that provides continuous position referencing from passive fiducial markers. The result is a highly accurate 6-DOF tracking solution with no active optical components.

IS-1200 Configurations

The IS-1200 product family is designed with a flexible architecture to support applications requiring high accuracy, low latency motion tracking. The details of the IS-1200 architecture are discussed in the paper titled "Generalized Architecture for Simultaneous Localization, Auto-Calibration, and Map-building".

IS-1200 VisTracker

The VisTracker utilizes passive position reference targets (fiducials) in a distributed pattern throughout the tracking volume to provide stable 6-DOF tracking output. The development of the VisTracker and its performance are presented in the papers titled "VIS-Tracker: A Wearable Vision-Inertial Self-Tracker" and "Miniaturization, Calibration & Accuracy Evaluation of a Hybrid Self-Tracker". The core tracking software (SFServer) can run on either a Windows PC computer or optional Wearable Sensor Fusion Processor. SFServer interfaces to all platforms supported by the standard InterSense Libraries.

PRELIMINARY IS-1200 FlightTracker

The FlightTracker, currently being developed under a US Army SBIR award, utilizes the flexible architecture of the IS-1200 with both outside-in and inside-out InertiaCams tracking active, pulse encoded LEDs. The placement of multiple InertiaCams provides a reference for motion as required in flight cockpits or moving vehicles. The multiple InertiaCams enable tracking accuracies of sub-millimeter in position and sub-mlliradian in orientation. Review the technical paper titled "FlightTracker: A Novel Optical/Inertial Tracker for Cockpit Enhanced Vision" for details about the FlightTracker architecture. A prototype IS-1200 VisTracker was demonstrated in the InterSense booth at I/ITSEC 2004.
