This talk is about taking pictures from above with a big latex balloon, helium, strings, duct tape and CHDK, and making a nice video with the pictures using python, GStreamer and OpenCV.
Some friends of mine and I got pretty busy last year on a crazy balloon photography project. I want to share that experience, say what worked (helium, CHDK, GStreamer) and what didn't (crazy kite-balloon ideas, arduino connectivity, and some other things, all due to a lack of time). Hopefully, that would motivate hackers to get out of their basement and go do cool things under the Sun.
