Euclid IMU Calibration

Is there a procedure for calibrating the IMU on the Euclid? I noticed some yaw drift. I have a diff-drive robot so not too worried about the other axis.

Hello Bruce_lunce,

 

 

Thanks for contacting Intel customer support.

 

 

In the following link you will find the procedure and the formula used for the IMU Euclid calibration.

Hope this helps to clarify your questions.

 

 

Best Regards,

From the link you referenced, I was able to view the IMU information by using this command (while camera running):

$> rosservice call /camera/driver/get_imu_info

But unsure how to modify the indicated values. I didn't see any parameters or services that looked like they were for setting them.

I posted on that link for clarification. If you know how to do that, maybe let me know.

Thanks.

So I got my answer. The sensor_msgs/Imu data in the published camera IMU topic is un-calibrated. You have to create a node to manually apply the calibration and publish the topic information.
