sFly: Search and Rescue of Victims in GPS-Denied Environments (no Vicon, no Laser, No GPS!)

Final demo of the sFly European Project (2009-2011). This demo simulate a search and rescue in an outdoor GPS-denied factory environment. No laser, no GPS are used for navigation and mapping, but just a single camera and IMU onboard each vehicle. All the processing runs onboard, on a Core2Duo.
Three quadrocopters take off using visual SLAM, explore the environment, build a 3D map of it, and use it to localize themselves and potential victims by measuring the signal strengths of WiseNodes carried by each victim.
