Resumo

Unmanned Aerial Vehicles (UAVs) are continuously being explored as important means of decreasing human intervention and improving system reliability. The more challenging tasks when operating with UAVs are take-off and landing. Most low-size UAVs can have their take-off performed by hand, but the capacity to perform autonomous landing is essential. The autonomous landing environment is usually challenging since we are considering a moving platform, and the system must be able to deal with Global Position System (GPS)-denied environments. The proposed system is based on a ground-based stereoscopic vision system with temporal filtering based on an Extended Kalman Filter (EKF) to track the position of a rotary-wing UAV during landing. The obtained position detects and guides the rotary-wing UAV during landing. The initial results indicate that this setup has the potential to track with low error, demonstrating its suitability for exploration and further improvements.
