Stereoscopic PIV imaging with enhanced precision & ease
3D PIV system is based on the original 2D PIV system but uses the principle of stereoscopic imaging to add the third dimension. At least two sets of cameras view the test area from different angles and with the two sets of two dimensional velocity vector components a third velocity vector component can be calculated within the test area. The image is ﬁrst calibrated, and afterward this third velocity component can be evaluated.
MicroVec3DPIVsoftwareincludescameraauto-calibrationspotsearchfunction,whichautomaticallydetectsthe spot, measures and adjusts the perspective distortion caused by the misaligned orientation of the cameras. The third velocity vector component can be then calculated using a stereoscopic imaging, resulting in 3D velocity vectors for the entire area.
Microvec 3D PIV system offers solution for perfect adjustment of the angle between the cameras and camera lens in order to focus correctly, which deploys the Scheimpﬂug principle. This is achieved by mounting the cameras on Scheimpﬂug mounts. MicroVec 3D PIV software supports patented Scheimpﬂug principle optical unit as well as Tilt/Shift lenses, which have a full angular adjustment (shifting, rotating and tilting) to make any orientation of the lens to satisfy the Scheimpﬂug condition. MicroVec 3D PIV system ensures multiple camera synchronization support for image acquisition from two cameras.
