| Abstract: | A 3D measurement system based on temporal phase unwrapping method is designed, with which the error propagation problem could be overcome. The system is used on the measurement of complicate surface or in bad environment. In the system, fringes are generated by computer and projected by liquid crystal projector, images are captured by CCD and digitized by frame grabber and saved in computer for further processing. The measurement is of completely automation and with high speed that only several seconds is needed for one measurement. Experiments completed with two special head model verify the advantages of the system. |
