I have been working on building an autonomous drone with collision avoidance and route navigation that do not rely on GPS.
I assigned the drone to fly towards the fridge. The drone sees the pole and successfully navigates to a new route to avoid the pole in an indoor, GPS-denied environment. The avoidance and navigation are completely vision-based with 2 stereo camera (one pointing forward, one pointing down).
Everything I used is based on this open source 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 🙂
