Computer vision and the drone – Update

There have been some major improvements concerning the drone “Follow the sign” application. The drone can now:

  • Determine the correct path to fly whenever a stop sign is detected
  • Do this even if the drone is currently not parallel to the ground
  • Follow the sign when it is detected

Nevertheless, there is still some work to do:

  • Sign detection is not as robust as I had hoped for. I’ll have to switch to something more simple (like detecting red spots).
  • The movement of the drone has to be calibrated very carefully.
  • The FOV of the bottom camera is indeed very limited. So I’ll have to detect relatively small spots or fly very high.

As soon as I succeeded with these issues, I’ll show you another video. As soon as it works well, I’ll provide the source code. Stay tuned!
