This repository is the central hub for the Field 3D PTV system: a complete modular 3D Particle Tracking Velocimetry (PTV) solution, developed and maintained by the Flow Field Imaging Laboratory, University of Minnesota.
Funding: This work was supported by the National Science Foundation under NSF Major Research Instrumentation program (NSF-MRI-2018658)
Most components (datasets, hardware files, and software) are hosted externally. Use the links below to access each part. If you have any questions, please contact Yue Weng at wengy@umn.edu.
The User Manual (.pdf) provides a complete guide to the Field3DPTV system, including:
- Product description: Overview of the hardware and software components
- Hardware: Imaging modules, central computer, calibration modules, and optional lighting and mounting systems
- Software: Remote camera control, calibration (easyWand5), and the OpenLPT tracking pipeline
- Image acquisition procedure: Setting up the system, camera alignment, and synchronized image collection
- Data processing procedure: From calibration marker extraction to particle trajectory reconstruction and visualization
- Demonstration cases: Step-by-step examples for Confetti Settling, Snow Settling, and Pollen Dispersion, including calibration and tracking results
Please read the User Manual carefully before using the demonstration cases or software modules.
