Fringe Projected Profilometry on a Mobile Phone

Abstract

Until now, various kinds of methods for 3D modelling have been proposed and some have come into use. However, current available approaches generally require a precise and huge set-up, which greatly limits the using scenario. To get rid of the limit of equipment and enable convenient measurement, we propose a method to reconstruct a 3D model using fringe projected profilometry carried out on a mobile phone, taking advantage of the now high developed computation ability of smart phone. A fringe pattern can be projected by a mini-projector and the deformed fringe pattern is captured by the camera of a mobile phone. Through phase retrieval and calibration, the point cloud can be calculated and displayed on the mobile phone. The interface of the devices and the algorithms of the system are researched and implemented. Experiment results have proved the effectiveness of the system and the system can thus bring 3D modelling to a much larger application scenario.
