This odd-looking ball can automatically take a panoramic image whenever you throw it up into the air. Seriously, that's then entire set of operating instructions for the device. Inside, a 3D printed frame hosts an array of 36 cellphone cameras, each capable of taking a two megapixel image. Also included is an accelerometer. When it senses the change in momentum associated with the apex of its vertical trajectory it snaps an image with all of the cameras at the same time. The result is a spherical image with no obstructions-like a tripod or other support mechanism. The images are automatically stitched together and displayed on a computer which allows the user to pan and zoom.

The whole story is told in the video after the break. The example images shown are quite good, although there are a few artifacts where the segments meet. Most notably, color variances between the images captured by different CCD modules. We'd image that this can be fixed automatically in software if a talented programmer were willing to put in the time. The thing about spherical photos is that methods using post processing to unwrap an image always have some distortion to them. With that in mind, we think the ball camera is as good a solution as we've seen.
