A Vision-Based Particle Tracking Velocimetry

Real-Time Imaging, 2001
Summary: Particle Image Velocimetry (PIV) is a non-intrusive optical technique to measure velocity of flows. It provides the simultaneous visualization of the streamline pattern in unsteady flows and the quantification of the velocity field over the image plane. To reveal the flow motion, the flow is seeded by small scattering particles.

Particle design for displacement tracking velocimetry

Measurement Science and Technology, 1995
Particle displacement tracking velocimetry is used to obtain full-field minimally invasive velocity measurement of natural convective flow in multiple immiscible liquid layers. The quality of the obtained signals depends very much on the particles used.

Particle tracking velocimetry applied for fireworks

Journal of Visualization, 2008
Particle tracking velocimetry (PTV) is applied for measuring the motions of luminous particles in fireworks. The objective of the study is to clarify the technical problems encountering in large-scale quantitative visualization in natural environment. The major problems are found to be uncontrolled background in nature, low pixel resolution relative to

Particle Tracking Velocimetry in Noisy Environment

Volume 1: Fluid Applications and Systems; Fluid Measurement and Instrumentation, 2020
Abstract The encoded Particle Tracking Velocimetry (ePTV) is introduce in this paper as a specific approach of Particle Tracking Velocimetry (PTV). This method is applied to track particles obtained from flow images that contain significant background noise and relatively low particle density.

Particle-tracking velocimetry with new algorithms

Measurement Science and Technology, 2000
New algorithms for particle-tracking velocimetry are proposed and tested with typical particle images showing two-dimensional fluid flows. There are new ideas not only in the algorithm of the particle tracking itself but also in that of the individual-particle detection.

New Particle Tracking Velocimetry

1999
Particle Image Velocimetry (PIV) is a non-intrusive optical measurement method to capture flow velocity fields. It provides the simultaneous visualisation of the two-dimensional streamline pattern in unsteady flows and the quantification of the velocity field over a plane. To reveal the flow motion, the flow is seeded by small scattering particles. The

Particle tracking velocimetry: an automatic image processing algorithm

Applied Optics, 1989
A quantitative full-field velocity measurement technique involving imaging of displaced particles in a fluid is described. In this paper a fully automatic image processing procedure is developed to extract velocity vectors from flow visualization images.
