Throwable Panoramic Ball Camera



Jonas Pfeil of the Berlin Technical University throws a panoramic ball camera near the Brandenburg Gate in Berlin, October 28, 2011. The device contains 36 mobile phone cameras that take a picture at the highest point of the ball's trajectory. A computer program subsequently merges all pictures to a 360 degree image that can be viewed on a monitor by dragging the mouse in the desired direction.

Armed with 36 2-megapixel mobile phone camera modules, the camera contains an accelerometer that lets the exposure
be trigged at the calculated climax of flight, when it is hardly moving. the taking of a single photograph at the same moment
by multiple cameras prevents the ghosting effects that occur when creating a panorama by taking and stitching sequential images,
as well as the difficulties of recording a complete 360-degree view when using a tripod mount.

the sphere of the camera itself is printed on a 3D printer. its functionining is controlled via ATtiny and AVR microcontrollers,
with the governing program written in C, C++, QT, and openCV. images are downloadable from the device via USB.

pfeil and his team (kristian hildebrand, carsten gremzow, bernd bickel, and marc alexa) are currently seeking partners to produce the camera.
