One of the very first tablets with a built-in DLP projector has recently appeared on the market while smartphones with a built-in projector have been available around for quite a while. Interestingly, 3D reconstruction solutions on mobile devices never considered exploiting a built-in projector for the implementation of a powerful active stereo concept, structured light (SL), whose main component is a camera-projector pair. In this work we demonstrate a 3D reconstruction framework implementing SL on a tablet. In addition, we propose a 3D registration method by taking the advantage in a novel way of two commonly available sensors on mobile devices, an accelerometer and a magnetometer. The proposed solution provides robust and accurate 3D reconstruction and 3D registration results.
