IMU algorithms not needing a driver

[SteveBiomed]

I have a hardware system consisting of a 3-axis accelerometer and gyroscope for which I already have a serial protocol and DDE link into LabView 9. The data are easily decoded and become available as numbers within LabView, so no hardware drivers are needed. What I am now looking for are the algorithms to process these data in real time within LabView to determine the IMU output parameters such as 3-axis attitude and position. I imagine this involves Kalman filtering too. Can anyone tell me what vi's are available for this please? Thanks.

Hello Steve,

It looks like this is something which has come up on the forums before, hopefully these links will be of some help:

The Control Design and Simulation toolkit & the system indentification toolkit does include some Kalman filter VIs.

This might be helpful too:

It pulls the data from a file and merges the signals.

I would certainly reccomend a search of the forums too.

I hope this helps, good luck with your project.
