Help me build a DIY UAV to make small DEMs!

I want to put together an unmanned aerial vehicle for capturing aerial photos over a small area (probably <1 km2). Ultimately, I would like to be able to extract a digital elevation model from those photos. How can I get started?

I have read a bunch of stuff over at DIY Drones
but I still need some help putting it all together. I know a lot about GIS analysis but not as much as I'd like about remote sensing. I want to build a relatively cheap UAV, but I'm not sure what kind of firepower will be required to get the kind of resolution I need. I need the photos & georeferencing to be good enough to use an image processing service or program (e.g. Drone Mapper
) to generate a DEM from overlapping aerial orthophotography that I collect with the UAV.
What is the cheapest way I could do this and still end up with a usable product with high enough resolution to (for example) generate 2 foot contour lines from my DEM?
