Users can use the stereomaton to take photographs of themselves and view them in 3D thanks to appropriate equipment (3D display, cardboard, vr headset, etc.) of their own. The stereomaton generates a (readable) code they can use to retrieve the photograph on a specific webpage.
The stereomaton is based on StereoPi hardware (board + two cameras) with SLP variant image of Raspbian (version 0.2.3 used) with a 3.5" SPI LCD display using fb_ili9486 driver.
Note that LCD driver and its configuration, touchscreen driver, python as well as evdev, opencv, numpy and pycairo modules are assumed installed on the system for the code present in this repository.
