New Perspectives

I have been messing around with a quadcopter this last week, trying to get aerial footage that I can turn into spherical panoramas. I have read a lot about it on the net; techniques, fields of view, panorama software, etc. December weather being what it is, I have only managed two separate flights on the hill behind my house. It was sunny on both occasions and the low hanging sun caused exposure problems due to effectively being 'under' the propellers. I have tried three different software programmes to produce the panoramas, with greater or lesser success but it has been fun, if a rather steep learning curve. Above is a 'little earth' projection. Rather pretty!

What I am actually trying to get is this:

Ok, it's not perfect. I am still working out how to get the best angles so that the fields of view overlap and I don't have any holes. It is supposed to be completely spherical, which means if you scroll upwards you should see sky all round. Here, we have more of a cup or a sphere with the top cut off. Getting the sky in is easy to do with a terrestrial panorama, just point straight up to your zenith and shoot. With a quadcopter though, all you will see are the undersides of the arms and the propellers. Some panorama folks like to photoshop in stock images, I don't really see the point. As long as I have some sky and a horizon, it is what is on the ground that holds my interest.

Meanwhile I will play some more with the software and see what I can produce.
