演示了使用自上而下的照明光度立体成像装置和手持移动电话设备进行物体的三维重建。通过采用白色发光二极管的二进制编码调制进行场景照明，该方法与标准照明基础设施兼容，并且无需光源和相机的时间同步即可进行操作。三维重建对于未调制的背景光具有鲁棒性。对于距离 42 厘米、尺寸为 48 毫米的物体成像，报告的误差为 2.69 毫米。我们还演示了运动物体的三维重建，有效离线重建速率为 25 fps。
Three dimensional reconstruction of objects using a top-down illumination photometric stereo imaging setup and a hand-held mobile phone device is demonstrated. By employing binary encoded modulation of white light-emitting diodes for scene illumination, this method is compatible with standard lighting infrastructure and can be operated without the need for temporal synchronization of the light sources and camera. The three dimensional reconstruction is robust to unmodulated background light. An error of 2.69 mm is reported for an object imaged at a distance of 42 cm and with the dimensions of 48 mm. We also demonstrate the three dimensional reconstruction of a moving object with an effective off-line reconstruction rate of 25 fps.
