Test data for OpenPTV "cavity"

This is a set of data measured using 3D-PTV method and kept in a working folder suitable for the OpenPTV software (www.openptv.net)

How to use it

git clone https://github.com/openptv/test_cavity
python pyptv_gui.py test_cavity

Source of this data and credits

This set of data is recorded at the Alex Liberzon laboratory at the School of Mechanical Engineering, Tel Aviv University, http://turbulencelab.sites.tau.ac.il by the team of Reut Elfassi, David Ratner and Mark Kreizer (all Master students at that time)

The setup is a lid-driven cavity in a cubic cavity of a 1:1:1 ratio. The top lid is a plastic belt driving system constructed for our laboratory by the I.T.E.S. http://www.ites.co.il/index.html

The 4 cameras are located on two sides of the cavity (positive and negative 'z'). More details are available from the Reut Elfassi (Kramer) thesis.

Working with plugins

Plugins is a system of extensions to PyPTV without the need to change the GUI

1. copy the sequence_plugins.txt and tracking_plugins.txt to the working folder
2. copy the plugins/ directory to the working folder
3. modify the code in various plugins so it performs instead of the default sequence or default tracker
4. Open the GUI and Plugins -> Choose , then run the rest: Init -> Sequence

Note, the specific branch plugin_remback requires installation of the pip install rembg[cpu] or pip install rembg[gpu]
