I have spent some time last year creating a Particle Imaging Velocimetry system to be employed to monitor analogue modelling experiments of tectonics. Basically an image correlation technique is used together with a calibration function to calculate physical displacements and deformation in the models.
My PIV software has been published and is available now. I will post resources soon to help getting started. But first here are some videos of the software. The software has successfully been used last year by my students David Beckett and Maxime Henriquet. It allowed them to quickly become able to quantify their experiments. The example of exported result in the video below is from Beckett’s work. The shear zone setup in the first video is from Maxime’s work.
