I am looking at the DCM algorithm code re-implementation at http://code.google.com/p/ardu-imu/source/checkout. Does anybody know if this codebase supports dead-reckoning based on an absolute (GPS) or relative coordinate system?
It appears that some initial implementations of Bill Premerlani’s DCM algorithm had dead-reckoning (http://code.google.com/p/gentlenav/source/browse/trunk/libDCM/deadReckoning.c?r=591) as part of MatrixPilot, but it’s unclear whether even that implementation supported dead reckoning in non-GPS situations (ie magnetometer).
I’d like to precisely track the relative location of an object indoors, as well as its pitch/roll/yaw. Any guidance would be appreciated.
No public wish lists :(
