A low cost multispectral imaging payload for a UAV

Ok. So as you've gathered, this whole keeping-a-record-on-here-while-I-do-my-dissertation thing hasn't exactly gone to plan... turns out I'm not very good at it. But fear not! the dissertation is over! I have a working camera system and a working(ish... it's rather barebones and there's plenty that can be improved) software system for processing the camera data.

I'll do a few posts over the next couple of days giving you an idea of how it works and what's still left to do, and I'll get the current source code up so people can have a poke around too. For now I will leave you with a few pictures taken out of my window with the system. Enjoy :)

Mosaic from the Green filter (turns out it actually lets a lot of NIR light through too) :

And a nice false colour image made by combining the two:

Incase you're wondering, this is what the raw frames from the camera look like:

I realise I haven't been updating this as much (at all) as I should so far, I don't have time right now but I thought I'd say that progress is being made, and I <failed commitment> will post a proper update .</failed commitment> (edit: I've had less time than I thought I would, especially seeing as I almost committed the cardinal sin of forgetting mothers day... The update will now be posted soon!)

Just to show where I'm at, I've added a link to my project on github so you can look at my code. I must be clear, it's not very good code right now! Please do not assume that it's current status is reflective of future readability/quality! So far I've just been hashing stuff out to try and throw a prototype together, one of my jobs this weekend is to do a big refactor so it's no longer embarrassing.

Other jobs include adding multithreading where appropriate, making some test footage that's representative of what the camera will produce, and getting the system to track all filter regions semi independently. I promise to clarify what all this means in this weekend's post...

Anyway, I should probably get back to work... bye!
