Description

ALPR (Automated License Plate Recognition) is a multistage software application designed for the identification and registration of cars' license plates within parking lots or road areas, in both constrained and unconstrained environments

General Notes

• The project was primarily designed to be integrated within an end-to-end real-time embedded IoT application in public parking areas.
• The package was tested in the development process on Raspberry-pi-3, Model B+, 2017 Before the integration of Yolo v3, you may encounter installation or runtime conflicts. If this happens, please open an issue. issue
• Streaming data from the default Raspberry-pi camera module function is not tested, can lead to perfermances issues.
• other embedded platfoms are not testd or supported
• For C++ devllopers, there is no option to use this version with C or C++.

Build and Installation

Warning: Building OpenCV-lib from source, which is a dependency of the project on Raspberry Pi boards, can fail and consume time. We recommend checking the suitable version of OpenCV for the board and installing the precompiled Python packages for OpenCV listed in the requirements

Build

To build the package using python setuptools run :

python setup.py sdist --dist-dir build

It will generate a distributable version under the build/ directory.

or with :

python -m build 

to get a *.tar.gz and *.whl files under the dist/ diractory.

Installation on Raspberry pi Board

Update package information and upgrade installed packages

    sudo apt update
    sudo apt upgrade

Upgrade Python packages: pip, setuptools, and wheel

pip install --upgrade pip setuptools wheel

Install library dependencies

sudo apt install python3-opencv libopencv-dev

clone to the repository

git clone git@github.com:wissem01chiha/ALPR.git

Navigate to the repository folder and run

pip3  install ./dist/cil4sys-0.1.1.tar.gz

This will install the application with it dependencies and data files.

Usage

connect your camera to raspberry pi board throgh the USB port or the default raspiberry port, only one camera wich is ste to default will be detected for the raspi kit camera you miust enable the camera interface

after installation navigate to the main script diractory folder and run :

python3 main.py
