Abstract
In this article a 3-d particle tracking velocimetry system (PTV system) is presented which enables the investigation of relatively fast gaseous (air) flows and tiny turbulences in a small scaled wind tunnel. To satisfy the demand of a high spatial and temporal resolution, a sufficiently high tracer particle concentration has to be applied to the gas. Solving the correspondence problem among different cameras becomes extremely difficult due to ambiguities: Each tracer has to be found in all pictures of the different views during many successive time steps. Here, the correspondence problem is facilitated by the use of coloured particles and the application of suitable classifiers for particle classification.
