This is a simple tool that reads screenshots of the Treasure Hunter Monolith puzzle minigame Danganronpa V3, and exports a CSV file representing the board, automatically. It uses Python and OpenCV.
The output CSV can be used in other tools, for example, DanLeEpicMan/UpdatedMonolithSolver and artur-ag/treasurefinder.
- Install Python 3 (any recent version should work)
- Install OpenCV with
python -m pip install opencv-python
This is a command line tool. Use the -h flag to get the help message:

The tool computes the dominant color of each cell, compares it to the 4 colors, and outputs the closest color for each cell. If none of the colors are similar enough, it outputs 0. This makes the tool robust to screenshots in JPG.
The image is resized, so the tool should work with any resolution, as long as the screenshot is 16:9 and doesn't have black bars around it. It only works on the Mean difficulty (22x11 boards). You can adapt it for other difficulties by editing the script yourself.
