Computer Vision Driven Micro- Aerial Vehicle (MAV): Obstacles Avoidance Lim-Kwan (Kenny) Kong - Graduate Student Dr. Jie Sheng - Faculty Advisor Dr. Ankur Teredesai - Faculty Advisor Lim-Kwan (Kenny) Kong - Graduate Student Dr. Jie Sheng - Faculty Advisor Dr. Ankur Teredesai - Faculty Advisor

The Idea Using quad-rotor (quad-copter) Stream video using mono camera Detect static obstacles using computer vision algorithms Avoid the obstacles

Steps 1. Reverse engineer the AR.Drone 2. Implement 2-3 obstacle avoidance algorithms 3. Testing 4. Collaboration: 1. Ji’s object tracking algorithm 2. Sid’s Pi-map reduce algorithm

Obstacle avoidance Algorithm Figure 2. Optical flow differences [2] Figure 1. The basic program flow

Outcome Basic Avoids obstacles in flight Advanced Avoids obstacles in flight while tracking a designated object (Ji) using Pi-map reduce algorithm (Sid).
