The paper presents some principles of Stereo PIV measurements of instantaneous velocity fields in liquid and gas flows. The problem of camera calibration for an optical stereo system in relation to the optical methods for velocity measurements is described. Possible causes of errors in Stereo PIV experiments are shown. A numerical algorithm for the calibration correction is proposed to simplify the process of system adjustment prior to velocity measurements. Two methods for the stereo reconstruction of velocity fields are described. All proposed algorithms are tested with the use of real experimental data.
Keywords:
camera calibration, Stereo PIV, pipe flow.
