Cylmarker

This marker can be used to estimate the 6DoF (location + orientation) of cylindrical objects.

How to run the code?

We recommend you to create a Python virtual environment:

python3.9 -m pip install --user virtualenv
python3.9 -m virtualenv venv

Then you can activate that environment and install the requirements using:

source venv/bin/activate
pip install -r requirements.txt

Now, when the venv is activated you can run the code using:

python main.py

Feel free to adjust the settings in data/config.yaml file. You can easily adjust the HSV values (to segment the green marker) using:

python main.py --task a

How to create a new marker?

Edit the data/config.yaml file. Then, run the following command:

python main.py --task m

The resulting marker will be inside the folder data/ and is ready to be used.

How to print the marker?

Follow the instructions shown in the data/marker_how_to_print.svg file.
