| Description | Journal: Measurement Science and Technology A novel method of geometric dimension assisted absolute phase recovery in 3D shape measurement is presented. This method mainly includes two steps: (1) using the window Fourier filter-quality guided phase unwrapping algorithm to obtain the relative phase distribution of the tested object; (2) using geometric dimension of the object as a clue to convert the relative phase distribution to absolute phase distribution. This method is convenient and with only three fringe image acquisitions to recover the absolute phase. In addition, there is no limit to the depth range of the tested object. The correctness of this method is verified by several experiments. |
