If you are interested in this, I strongly encourage you to watch Andrew Tridgell's talk from linux.conf.au 2012: https://www.youtube.com/watch?v=ML__e_ZcWiQ. It was close to my favourite talk at that conference.
From the youtube video: "This talk is all about the technology and techniques that we have developed for building an Unmanned Aerial Vehicle (UAV) that can search for and find a lost bushwalker in outback Australia"
Tridge is a great speaker, and discusses the nuances of this topic really well.
