Abstract

The algorithm used by DLR for the Second PIV-Challenge is a combination of pyramid-based grid refinement (multi-grid) and full-field image deformation which is intended to give second-order accurate displacement data. At its core a standard FFT-based correlation algorithm provides local image shift data. Special emphasis was placed on striking a balance between accuracy, robustness and processing speed.
