Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams
Uncertainty Of Stereo Piv Calibration And Self-Calibration, Braydon J. Williams
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Particle image velocimetry (PIV) is a widely used fluid measurement technique. Three dimensional PIV data or stereo PIV is acquired using two cameras. Stereo cameras are calibrated from camera coordinates, pixels, to real world units such as millimeters using calibration models. Stereo calibration is fundamental to the accuracy of a PIV measurement. In this thesis, the accuracy of the stereo calibration is assessed. The mean error of stereo calibration was found to be 0.23%.
