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
