AI-Based Obstacle Avoidance for UAV Path Planning

Autonomous drone system for exploration and reconnaissance in unknown environments. The system allows the drone to autonomously fly, map the environment, locate targets, avoid obstacles, and return home. The drone acquires data from cameras, lidar, and IMU to estimate pose, recognize targets, and generate a 3D map. It plans safe paths using ray-casting and sensor fusion. The drone applies the path to fly autonomously. This allows it to explore unknown areas, accurately locate targets, avoid obstacles, and return home.
