Sensor Data Fusion Framework to Improve Holographic Object Registration Accuracy for a Shared Augmented Reality Mission Planning Scenario

Accurate 3D holographic object registration for a shared augmented reality application is a challenging proposition with Microsoft HoloLens. We investigated using a sensor data fusion framework which uses both sensor data from an external positional tracking system and the Microsoft HoloLens to reduce augmented reality registration errors. In our setup, positional tracking data from the OptiTrack motion capture system was used to improve the registration of the 3D holographic object for a shared Augmented Reality application running on three Microsoft HoloLens displays. We showed an improved and more accurate 3D holographic object registration in our shared Augmented Reality application compared to the shared augmented reality application using HoloToolkit Sharing Service released by Microsoft. The result of our comparative study of the two applications also showed participants' responses consistent with our initial assessment on the improved registration accuracy using our sensor data fusion framework. Using our sensor data fusion framework, we developed a shared augmented reality application to support a mission planning scenario using multiple holographic displays to illustrate details of the mission.
