I have been posting a series of tutorials on how to build an autonomous drone.
This time I am giving an example of using QR Code to visually guide drones to land.
QR codes provide rich visual information for locator, tracker and identifier. We will be using concepts such as homographic matrix, rotation and translation of images to guide the drone to land right next to a QR code.
If this is your first time attempting this tutorial series, please start from the very beginning so you have all the right dependencies.
Download the framework at this GitHub repo
Episode 1: OFFBOARD mode and Gazebo simulation
Episode 2: Build a 3D Model with Your Drone
Episode 4: Depth Estimation, Octomap and Path Planning
Everything I used is based on this GitHub project GAAS, which I built from scratch. I meant to provide an open source framework for autonomous drone development. Give me a star on GitHub if you find this helpful 🙂
PS: I have finally started a Facebook Group for these tutorials and the project GAAS. I thought that’s a good place for everyone to exchange tutorial ideas and help each other out.
