Switchblade Score-Tesseract OCR

by reyzeal (Rizal Ardhi Rahmadani)\

About Project

This is documentation of my Freelancer project. The goal of this project is to extract all information on the scoreboard from Switchblade games using Tesseract OCR as the core technology.

About Switchblade

Switchblade is an arena-based 5v5 vehicle action game that combines high-octane combat with an ever shifting selection of strategic choices. https://www.switchbladegame.com/

About OCR Engine environment

Environment Ubuntu Server

Python 3.x and Flask as web service
Tesseract-OCR 4, english language
OpenCV 4.x with dnn to use EAST Text Detection

Manual Installation

First of all, make sure you have Python3 installed
```
 sudo apt-get install python3 python3-pip
```
Install Tesseract-ocr
```
 sudo apt-get install tesseract-ocr
```
Install the dependency library
```
 sudo apt-get install libsm
```

Download my source code to your specified server directory

cd ~
git clone https://github.com/reyzeal/score-tesseract
cd score-tesseract

Install the virtualenv to make python environment for this project
```
 pip3 install virtualenv
 python3 -m virtualenv venv
```
Activate the environment
```
source venv/bin/activate
```
Install all requirements library using requirements.txt
```
 pip3 install -r requirements.txt
```
you can try to run it:

    venv/bin/gunicorn -b 127.0.0.1:5000 app:app

Done, if you prefer to run it as server service, stop the execution and do the following steps below.

Deploy as Systemd Service

You can use the template file that I’ve put in the folder server > score.service. If you know how to use vim / nano, you can directly create new file in /etc/systemd/system/score.service using this command : “sudo nano /etc/systemd/system/score.service ”.

[Unit]
Description=Reyzeal Score Tesseract Gunicorn daemon
After=network.target

[Service]
User= ubuntu
Group= ubuntu
WorkingDirectory= /home/ubuntu/score-tesseract
ExecStart= /home/ubuntu/score-tesseract/ venv/bin/gunicorn -w 3 -b
127.0.0.1:5000 app:app

[Install]
WantedBy=multi-user.target

Change all variables, focus on the red mark:

User= Group= WorkingDirectory= /path/to/project ExecStart= /path/to/project/ venv/bin/gunicorn -w 3 -b 127.0.0.1:5000 app:app

Save the file on /etc/systemd/system/score.service. Just save and close it if you already using vim / nano directly.
Enable and start:

    sudo systemctl enable score.service
    sudo systemctl start score.service

Check the status, it must be look like this:

sudo systemctl status score.service

Apache2 Configuration

If you want to make proxy through apache2 (make it public), you can add this following lines to your current site config file.

ProxyPreserveHost On
ProxyPass / [http://127.0.0.1:5000/](http://127.0.0.1:5000/)
ProxyPassReverse / [http://127.0.0.1:5000/](http://127.0.0.1:5000/)

Note : Make sure you have these mod enabled:

sudo a2enmod proxy
sudo a2enmod proxy_http
