3D model reconstruction algorithm and implementation based on the mobile device

With the mobile phone has been developed rapidly now, 3D reconstruction applied in this mobile device becomes a possible. Based on the photometric stereo, a 3D model reconstruction algorithm had been put forward, which can be run on mobile-phone with android system. In the dark environment, through several light sources provided by the mobile-phone screen, multiple perspective images of an object can be captured, then each value of depth can be calculated. Finally based on depth data, OpenGL ES have been used to map out the object model. Through experiments, the proposed algorithm is effective.
