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:

The code is publicly available and free to use. Codes are ideal for government applications like driver's licenses because they can store photos, fingerprints, signatures, text, numbers, and graphics. PDF417 - These codes can store huge amounts of data up to 1.1KB. Codes have the advantage of being very robust and fast to read. QR codes are free and publicly available.ĭataMatrix Code - Popular for logistics and operations, these two-dimensional codes are tiny in size and are ideal for labeling small items such as electronic components. QR codes support numeric, alphanumeric, byte / binary codes and hieroglyphs. QR codes are two-dimensional matrix codes intended for consumers and marketing. QR code is one of the most common 2D codes. Code 128 barcodes for use in the internal supply chain can store a variety of information. Code 128 encodes both numeric and alphanumeric text. Code 39 is the simplest of the alphanumeric codes, it is designed to self-test characters and is often used internally by small businesses.Ĭode 128 is used in transport and logistics, Code 128 is a high density ordering and distribution code.

Code 39, as the name suggests, can contain up to 39 characters in a barcode. There are also options such as ISBN and ISSN for more specific applications.Ĭode 39 - used in defense and automotive. The code differs from the UPC code in that the additional first digit identifies the country of origin code. The code consists of 12 numbers, and encodes a country code, company code, and product code.ĮAN is the European equivalent of UPC codes. You can found this barcode on any product. UPC is a 12-digit one-dimensional barcode used primarily in the United States for retail and consumer products. There are many different barcode symbologies for different applications.
