Use an existing virtual environment that has OpenCV ready to go (skip this step and head to Step 3).
#MAC BARCODE SCANNER USING CAMERA INSTALL#
Step 2 (Optional): Create a virtual environment and install OpenCV Installing ZBar for macOS using brew is equally as easy (assuming you have Homebrew installed): $ brew install zbar Installing ZBar for Ubuntu can be accomplished with the following command: $ sudo apt-get install libzbar0 Step 1: Install zbar from the apt or brew repository

Installing the necessary software is an easy 3-step process. Detect and localize exactly where in the image the barcode is.Use Python 3 (the official zbar Python bindings only support Python 2.7).The instructions to install ZBar in today’s post are largely based on his instructions, but with a few updates, the largest one being related to how we install the Python zbar bindings themselves, ensuring we can: Installing ZBar (with Python bindings) for barcode decodingĪ few weeks ago Satya Mallick from the LearnOpenCV blog posted a really great tutorial on using the ZBar library to scan barcodes.

Starting with a single image will give us the practice we need to prepare for the next step: Reading barcodes and QR codes in real-time with OpenCV and ZBar,įinally, I’ll demonstrate how to deploy our real-time barcode scanner to the Raspberry Pi. Once ZBar and OpenCV are properly configured I’ll demonstrate how to scan barcodes and QR codes in a single image.
The ZBar library will be used together with OpenCV to scan and decode barcodes and QR codes. In the first part, I’ll show you how to install the ZBar library (with Python bindings). Today’s blog post is broken into four parts.

Looking for the source code to this post? Jump Right To The Downloads Section An OpenCV barcode and QR code scanner with ZBar To learn more about reading barcodes and QR codes with OpenCV and ZBar, just keep reading. Inside today’s tutorial, I will show you how to read barcodes and QR codes with OpenCV and ZBar.Īnd as an added bonus, I’ll demonstrate how to deploy our barcode scanner to the Raspberry Pi as well! One set of ZBar bindings in particular, pyzbar, is my personal favorite. The ZBar library, along with its various forks and variations, have come a long way. If this sounds like a complicated process, it’s actually pretty straightforward. OpenCV can come back in to perform any further processing and display the result.
The ZBar library will then decode the barcode or QR code. Once we have the image or frame we can then pass it to a dedicated Python barcode decoding library such as a Zbar. However, what OpenCV can do is facilitate the process of reading barcodes and QR codes, including loading an image from disk, grabbing a new frame from a video stream, and processing it. The short answer is no, OpenCV does not have any dedicated modules that can be used to read and decode barcodes and QR codes. Keep doing what you’re doing.ĭoes OpenCV have any modules that can be used to read barcodes or QR codes? Or do I need to use an entirely separate library? Hey Adrian, I really love the PyImageSearch blog. Today’s blog post on reading barcodes and QR codes with OpenCV is inspired by a question I received from PyImageSearch reader, Hewitt: Click here to download the source code to this post
