Analysis of stereoscopic PIV measurements using synthetic PIV images
Résumé
This paper describes the use of a synthetic image generator (SIG) for the assessment of the precision of a stereoscopic PIV system. The geometry implemented with the SIG closely matches that of an existing stereo-PIV measurement in laminar pipe flow. The calibration procedure is simulated, which demonstrates the necessity of a careful alignment between the calibration target and the light-sheet plane. This demonstrates the possibilities for determining the tolerances for alignment and optical configuration prior to the actual measurement, which can save substantial costs during measurement campaigns in wind tunnel facilities.
