Project OverviewBen Falconer
BackgroundA bit about me
Ben FalconerCame to Warwick 2006Computer and Information engineeringMEng project
Project based around PIVCurrent experiments taking place in
Farnborough
Particle Image VelocimetryUsed to map the velocity
of a flow field cross sectionLaser creates a light sheet
through the flowCameras take quick series
of imagesCorrelation yields
velocitiesMultiple cross sections
create a 3D map of the flow field Image courtesy of

Stereoscopic PIVPIV using two
cameras in steroSimilar to our eyes
Resolves 3D positions

ProcessingResolve stereoscopic images
Produce a 3D plot of the field from two stereoscopic images.
Cross-correlationFind movement of each
particle within the 3D plotsProduce a velocity mapping
for the planePlane stitching
Join each plane mapping to form a full area mapping Image courtesy of
