Hi all,
I am trying to calibrate the optical flow sensor as per the documentation in arudupilot website. When I tried rotating that then the flow x and body x are almost coinciding, when the drone is not moving the flow x and y are very noisy as shown in the image below.

Please help me to solve this.
Thank you.
