opencv-steel-darts served with django

Goals and ideas:

We would like to build a UI where a user is presented with both the image capture of the game and the appropriate scores as well as an option to run games and correct scores determined by the image capture system.
In the end, we hope to have a fully automated system to run darts games

Requirements:

  • modified version of opencv-steel-darts
  • mariaDB (open source DB), required to capture data
  • django

Current dependencies and set up details:

  • Python version 3.5.x

  • Here's a list of the dependencies that are contained in the requirements.txt file:

    astroid==1.6.1
autopep8==1.3.4
cycler==0.10.0
Django==2.0.3
django-mysql==2.2.0
isort==4.3.4
lazy-object-proxy==1.3.1
matplotlib==2.1.2
mccabe==0.6.1
mysqlclient==1.3.12
numpy==1.14.1
pep8==1.7.1
pycodestyle==2.3.1
pylint==1.8.2
pyparsing==2.2.0
python-dateutil==2.6.1
pytz==2018.3
rope==0.10.7
six==1.11.0
wrapt==1.10.11

  • mariaDB should be installed

    • for development a DB should be set up like in the /orca_darts/settings.py file: 
          DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'darts_cam',
        'USER': 'darts_admin',
        'PASSWORD': 'R04X7qpA1dAoZ0Q',
        'HOST': 'localhost',
        'PORT': '3306'
    }
}
    • These are the commands used to initialize the DB and the admin user: 
      CREATE DATABASE darts_cam CHARACTER SET UTF8;
CREATE USER darts_admin@localhost IDENTIFIED BY 'R04X7qpA1dAoZ0Q';
GRANT ALL PRIVILEGES ON darts_cam.* TO darts_admin@localhost;
FLUSH PRIVILEGES;
    • verify that everything went well ;-) 
      SHOW GRANTS FOR 'darts_admin'@'localhost';
+--------------------------------------------------------------------------------------------------------------------+

+--------------------------------------------------------------------------------------------------------------------+
2 rows in set (0.00 sec)

mysql> SHOW CREATE USER 'darts_admin'@'localhost';
+----------------------------------------------------------------------------------------------------------+
| CREATE USER for darts_admin@localhost                                                                    |

  • use python manage.py createsuperuser and follow the instructions to add a superuser to administer the django instance from the web-ui (create/modify users)

  • We're also using OpenCV for image recognition. Follow the following to get a compiled cv2 linked intointo your virtualenv:

    name@Comp:~/.virtualenvs/darts/lib/python3.5/site-packages
$ ln -s /usr/local/lib/python3.6/site-packages/cv2.so cv2.so

Starting and running the darts ui:

To start the Django darts ui, change into the project folder (opencv-steel-darts). You'll find the manage.py script which can start Django and serve the UI. It comes with a few other tools also, but that is all described in the Django Docu.

Run the manage.py script:

# python manage.py runserver [[ip:]port]
python manage.py runserver 9000
