Reconstruction of 3D PIV data in complicated experimental arrangements
 Pavlík, D. ; Uruba, Václav ; Kopecký, V.
In this paper a three-dimensional reconstruction of flow field behind flat plate representing a wing\nis presented. The reconstruction is always performed for pair of 2D vector maps obtained by 3D PIV with two cameras which record measurement area from different locations. Three-dimensional reconstruction can be obtained in various ways. This paper summarizes two: the reconstruction based on the known correspondences and the reconstruction based on the knowledge of intrinsic and extrinsic parameters of cameras. The methods can be used in the cases when it is impossible to use a calibration pattern or when reconstruction by commercial software fails.
