Dewarping 360° Images @Raspberry_Pi #piday #raspberrypi

Via raspberrypi.org:

Katherine Scott, newly equipped with a Raspberry Pi camera board, was looking for an image processing challenge. She realised she had an unused panoramic lens for an iPhone rolling around in a drawer somewhere at home, and got to work with the silly putty and cardboard to hook it up to the camera board.

Since my RPI camera module is just loose, and not mounted to anything, I needed a non-destructive and quick way to attach the lens to the camera. I created three cardboard shims using my pocket knife, one that fit snugly to the camera, one that fit snugly to the protrusion on the lens, and one to space the two parts out. I used silly putty to “glue” the boards together while allowing me to slide them around to get the alignment just right. Silly putty works great for this as it is non-conductive and easy to pick out the RPI camera board without breaking it. Also cleans up fairly easily.

The raw output from a lens like this gives you a doughnut-shaped image and a lot of surrounding cruft – Katherine uploaded some unmanipulated footage from the camera to YouTube to demonstrate what she had to work with.

Raspberry Pi Camera Board – The Raspberry Pi Camera Module is a custom designed add-on for Raspberry Pi. It attaches to Raspberry Pi by way of one of the two small sockets on the board upper surface. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. (read more)
