Currently doing a project about drone precision landing by sensing April Tag using a raspberry PI camera and Raspberry Pi 3 with Pixhawk, can anyone give an insight to me on how to do this project?

Hello! I used Aruco markers. First I found the center of the marker, then I aligned the drone with the center of the marker and landed

Hey Jajazz_ratava,

  1. I'm assuming you're using ROS, then you can use http://wiki.ros.org/apriltag_ros pkg for detecting and getting pose of the April tag.
  2. On px4 you can use the offboard mode(The vehicle obeys a position, velocity, or attitude setpoint provided over MAVLink(API)), Here is an example of its implementation https://dev.px4.io/master/en/ros/mavr...
  3. Now you can give the April tag's pose to offboard mode for landing. I hope this helps.

Thank you

I am am not speaking from experience, but this paper explains how to handle the April tag landing on a Pixhawk PX4 it includes algorithm explianations and configuration files. You should be able to run PX4 as opposed to APM on Pixhawk (speaking from experience).

You're probably going to want to use Ubuntu on the Raspberry Pi. I've been running ubuntu-mate on rpi4b.

Thanks,

Aaron
