This application visualizes some intermediate steps of the aruco marker detection in OpenCV. This is supposed to help with parameter selection. Instead of fiddling with parameters until the overall results are ideal, one is able to fine-tune the parameters independently.
This application essentially copies the private implementation of OpenCV and adds some calls to push intermediary images to the GUI. The OpenCV version currently recreated is 4.5.5 (note that the aruco detection was reworked since then).

Currently, the application needs to be started from the commandline. Use the --help option to find out how exactly to call it.
For building the application, vcpkg can be used to install the dependencies from the vcpkg.json manifest.

For the GUI, we use FLTK.
For CLI parsing argparse.
And of course, for the aruco detection, OpenCV.
