| Abstract: | The phase unwrapping algorithm on the projecting fringe method of measuring the 3D topography is studied. A noise-immune 2D phase unwrapping method of the second difference of the locally continuous unwrapping phase is used to unwrap the phase map of a round cup. This method can process the region of interest automatically and leave the invalid data unprocessed. It is proved that this method has higher accuracy and needs less time than other methods. |
