Motion Calibration Failure with App v10.3.0 #12

Closed km414 closed 1 year ago

km414 commented 1 year ago

Hi Clarius Engineers,

When the Clarius Ultrasound App released v 10.3.0, I calibrated my probes and was successful with both the stationary and motion calibrations in the beginning of May.

However, the results of my imu data showed skewed yaw values (pitch and roll looked great). During Clarius Live calls, the window that depicted the probe failed to accurately depict the yaw of the probe. The pitch and roll were shown well, however the yaw drifted and lagged.

In the past couple days, I have attempted the motion calibration again numerous times on a couple probes. In all cases, the motion calibration is now failing, as it was during the 10.2 versions of the app.

Is there a reason as to why the motion calibration is now failing? Why are the yaw values for the imu data inaccurate?

Thank you!

Over the past couple weeks, the motion calibration has still been failing. Does anyone know what is causing this?

Hi there, you could try performing a factory reset on the device and trying calibration again.

For the yaw data, we don't have a lot of means to debug this, but you do have access to the 9DOF raw data where you can run your own yaw/pitch/roll calculations.

Thanks for the advice. The motion calibration has still continued to fail, regardless of numerous attempts and factory resets. Do you have any other suggestions?
