摘要：
In this paper a three-dimensional reconstruction of flow field in a tunnel with the Hump profile is 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 correspondence between images, and the reconstruction based on the knowledge of intrinsic and extrinsic parameters of cameras. The both methods can be used in the cases when it is impossible to use a calibration pattern or when reconstruction by commercial software fails.
