recalibrate imu? #25

Open 12tbuchman opened 7 years ago

12tbuchman commented 7 years ago

is it possible to recalibrate the imu? my imu is giving a constant offset (with gaussian noise on top of that) which I would like to normalize back to 0.

We usually use the Window's software provided with the imu to calibrate it.

It is possible to do via the API (http://files.microstrain.com/3DM-GX4-25%20Data%20Communications%20Protocol.pdf), but we have no plans to implement this feature in this ROS driver.

You're welcome to submit a pull request if you come up with a solution with the driver.
