Abstract

The paper studies three-component PIV techniques used in 3D flow field measurement. Lateral stereovision was employed to locate the spatial position of particles and a progressive approach was used to measure the position accurately. A new epipolar constraint algorithm for the corresponding match was put forward. The algorithm can reduce the search area under perspective distortion. Fuzzy pattern recognition was introduced to PIV adjacent frame matching and fuzzy clustering was employed to implement the moving analysis of local particles in double exposure PIV images. Finally, a simulated experiment of 3D PIV analysis was completed by the techniques mentioned above.
