Capture images from basler camera and perform consecutive differencing in real time. Intended for use with ESPI setup in CAML Lab at McGill University.
ESPI stands for Electronic Speckle Pattern Interferometry and is a method that can be used to visualize mode shapes of a vibrating object.
The ESPI system used in the CAML lab was designed by Thomas R. Moore.
Basler Camera model used in CAML lab: a2A3840-45ucBAS
- Install pylon : https://www.baslerweb.com/en/products/software/basler-pylon-camera-software-suite/
- Install pypylon using the following command (pip info: https://pip.pypa.io/en/stable/): pip3 install pypylon
- Install opencv using the following command: pip install opencv-python
- Install Tkinter using the following command: pip install tk
- Download the ESPIFINAL folder to your computer, make sure you note the path to this folder.
- Run the espifinal file in a terminal of your choice using the following command: python3 path to the espifinal.py file (ex: python3 C:\Users\calli\Documents\ESPIFINAL\espifinal.py)
- A window will appear with three options: live view, consecutive differencing(in black and white), and consecutive differencing (in color) choose which one applies to you
- Then two more windows will appear. One is the consecutive differencing or live view and the other is control over the different parameters
- Once done, click the esc key to terminate the program
