Particle Matching Algorithm for 3D-PIV Based on Delaunay Triangulation

Abstract:

In this paper, a new particle matching algorithm for 3D-PIV is proposed based on Delaunay triangulation and projective invariants. In the proposed algorithm, fuzzy similarity is first computed for the triangulation in the matching particle images and rough matching is executed. Then, error matching in the results of rough matching is removed based on projective invariants. Experiment results further demonstrate the effectiveness of the proposed method.
