Student Project (SEP aka Software Entwicklungs Projekt)
This project basically combines optical tracking of markers within AMIRE based on firewire video streams with traditional tracking techniques. Used to calculate and approximate the actual camera position & orientation the tracking system ART was additionally supported with the Intersense InertiaCube2. Using this allowed a previously unimaginable combination of reality with a very exact scenegraph (vrml/x3d) of the enviroment, allowing to display data & information in a very feasible way.
Tracker Systems Picture
First step was to create an VRPN Interface to communicate with the ART Tracking System via UPD on ethernet. (will be WLAN) Additionally some smoothing & extrapolation of the movement was implemented since...
Implemented Algorithms:
The ISD Interface establishes communication to the Intersense InertiaCube2 via serial port. The tracker calculates the orientation and is (usually) always valid. It is used so only the movement needs to be extrapolated and the orientation of the device is always correct. Since inertia trackers always have a certain drift it is permanently updated by the orientation information the ART gathers.
The VRPN and the ISD interface are both integrated into a threaded AMIRE component which also takes care of the calculation, validation and display of the information data. AMIRE can handle scene graphs and with our new component we can use it to create our part real, part virtual world.
More Information coming later.
