4D-PTV Particle Tracking

What is Particle Tracking Velocimetry (PTV)?

Particle Tracking Velocimetry (PTV) also known as Lagrangian Particle Tracking (LPT) refers to fluid mechanics measurement techniques to track particles. As the name indicates, this technique aims to build spatial and temporal trajectories. Particle tracking schemes are also known as Single Particle Tracking (SPT) in different scientific communities.

PTV techniques can be implemented for 2D or 3D particle tracking in experimental fluid mechanics. Time-resolved three-dimensional particle tracking velocimetry is known as 4D-PTV.
