DIC GUI Workflow

Overview

This document describes the workflow for the DIC GUI. The GUI is a graphical user interface for the DIC algorithm. It is written in Python using the tk GUI toolkit.

There are two separate windows for the gui:

• DIC analysis GUI: responsible for running the DIC analysis and obtaining strain map results. This code only uses data from the camera and the camera log file and exports a strain curve vs the time.

• Merge dic and UT: responsible for taking the output from the dic analysis (see above) and then merging it with the UT data.

the graphical procedure is outlined in the following diagram.

Currently :

• the DIC analysis GUI is implemented in the examples/dic_gui/tkapp_dic.py file.

• the Merge dic and UT GUI is implemented in the examples/imada_dic_merge_gui/tkapp_dic_ut_merge.py file.
