Configure the flight control parameters based on this manual - http://ardupilot.org/plane/docs/common-px4flow-overview.html,but Optical flow is not available in the new version firmware ArduPlane 3.8.1-dev and ArduPlane 3.8.2-dev.I hope friends can provide solutions.Thanks!
The PX4FLOW is supported as an experimental feature starting from Copter 3.3. It is not supported in Plane or Rover.
Thank you for your replay！I used the PX4Flow in plane3.7.1，and saw the data of the optical flow from the ground station,but nothing in plane3.8.0 above version.
@Awesome : Does it work well in version <= 3.7.1 ? I tested on parrot disco but show nothing with 3.8.x firmware ...
@kikislater I only saw the data of optical flow in the MissionPlanner ground station.I don't know the optical flow that works really well.Now I just want to use it in version>=3.8.0,not in version<=3.7.1.
Ok so if I understand well, you didn't use it for accurate landing, just testing in the first time. Am I right ?
Yes！ You are right.I didn't use it for accurate landing.
