This repository contains the tools needed to process digital image correlation (DIC) files. This includes:
- loading, saving and compressing
*.MATfiles - placing and analyzing extensometers
- plotting (x,y) data and contour overlays
- creating video frames and turning the image sequence into a video
The reference IPython notebook shown here
describes how to create a video that matches a sequence of DIC overlays to the corresponding stress-strain curve.
To ensure that all the required packages are available, navigate to the dic folder in the terminal and execute:
>>> pip install -r requirements.txt
See the documentation website for details on all the available functions.
The compress.py script is included as a convenient way of compressing .MAT files (those exported from the VIC
software are not by default). By running this script on the native output from the VIC software, total file size should
reduce anywhere from 4-5x. To compress your exported files navigate to the root DIC folder in the terminal, i.e. the folder
containing this README. Then execute python compress.py -i /path/to/input_files/ -o /path/to/output_directory/
If the output directory does not exist, it will be created.
