Paper Abstract

We present a new single-shot 3-D shape measurement method using a digital micromirror device (DMD) camera and fringe projection. In optics of the DMD camera, individual DMD mirrors operate as controllable high-speed shutters for corresponding charge-coupled device (CCD) pixels. Therefore, four phase-shifted images can be recorded within one frame of the CCD camera by integrated phase-shifting methods using correlations. To obtain 3-D information of the object, an easy and accurate phase-to-3-D calibration method is performed. The principle and hardware are presented. The experimental results under dynamic conditions show that 3-D shape information can be analyzed from only a single image.
