Abstract

Particle tracking velocimetry (PTV) is a well-known technique for the determination of velocity vectors in an observation volume. Here we present a fully automatic and efficient PTV method, which is based on the photogrammetric determination of particle coordinates in space. By this method we are able to determine about 100 vectors with satisfactory accuracy in an observation volume with a frequency of 25 time frames per second.
