Our camera uses 36 fixed-focus 2 megapixel mobile phone camera modules. The camera modules are mounted in a robust, 3D-printed, ball-shaped enclosure that is padded with foam and handles just like a ball. Our camera contains an accelerometer which we use to measure launch acceleration. Integration lets us predict rise time to the highest point, where we trigger the exposure. After catching the ball camera, pictures are downloaded in seconds using USB and automatically shown in our spherical panoramic viewer. This lets users interactively explore a full representation of the captured environment.

We used the camera to capture full spherical panoramas at scenic spots, in a crowded city square and in the middle of a group of people taking turns in throwing the camera. Above all we found that it is a very enjoyable, playful way to take pictures.

This project shows the great potential of the use of 3D printing to realize complex projects with bespoke housings without the usual expense of fabrication.  When it comes time for the next iteration with higher resolution cameras, different accelerometer or some other modification, the cost to produce the next version will be approximately the same as making another copy of the exact same housing.  This lowers the barrier of entry, encourages improvements and promotes innovation.  Check out the video below to see the unit in action.
