BarDecode

BarDecode is a simple barcode reader project that can read barcodes from both images and webcam video streams. It uses Python's opencv-python for image processing and pyzbar for barcode decoding. The project demonstrates two modes: reading barcodes from an image file or live from a webcam.

Features

• Barcode Detection: Detects and decodes barcodes from images and live camera feeds.
• Image Processing: Displays the decoded barcode with a rectangle drawn around it for easy identification.
• Support for Various Barcode Types: Can read various barcode types such as EAN13, QR code, UPC, etc.

Installation

1. Install Zbar Library

pyzbar depends on the zbar library to decode barcodes. You need to install zbar on your macOS machine.

To install zbar, you can use Homebrew with the following command:

brew install zbar

This will install the zbar library, which is required by pyzbar to function correctly.

2. Clone the repository

git clone https://github.com/yourusername/BarDecode.git
cd BarDecode

3. Set up a virtual environment (optional but recommended):

python -m venv venv
source venv/bin/activate  # On Windows use `venv\Scripts\activate`

4. Install the dependencies:

Install the necessary Python libraries with:

pip install -r requirements.txt

The required packages are:

• opencv-python - For image processing and displaying the barcode in images.
• pyzbar - For decoding barcodes from images.

Usage

You can run the project in two modes:

1. Reading from an Image

To read barcodes from an image, call the read_barcode_from_image() function and provide the image path.

read_barcode_from_image('path_to_image_file.png')

It will display the image with a rectangle drawn around the barcode and output the decoded barcode data to the console.

2. Reading from the Webcam

To read barcodes in real-time using your webcam, call the read_barcode_from_camera() function.

read_barcode_from_camera()

Press ‘q’ to exit the webcam feed.

Example

Reading Barcode from an Image:

python main.py

The output will look like:

Decoded Barcode: 1234567890128 (Type: EAN13)

Reading Barcode from Webcam:

Run the following command:

python main.py

The webcam will start, and you can scan barcodes in real time. Press ‘q’ to stop the webcam feed.
