A new image processing technique for three-dimensional measurement of fluid velocity field is proposed in this paper. The technique is based on cross-correlation method and requires gray-level digital data of three-dimensional flow field. They are reconstructed on the EWS from the series of pictures that shows vertical section of flow field visualized by moving laser light sheet. One of the matters with this technique was that it took huge computational processing times. To reduce this problem, the program code is parallelized with MPI, standard portable message passing system. This technique is applied to vortex flow. And the results are compared with the results measured by LDV.
