Recognizing and decoding the barcode/QR code that we will be showing to the camera.The decoding function will be doing mainly three things, and can be listed as follows: In this step, we write the decoding function, where most of the cool things will be happening. You can also learn more from Pyzbar’s official documentation page.

I will show both Mac OS and Windows installation lines. Installation of Pyzbar library is different depending on the computer you are using. Reference: pip install opencv-python Pyzbar OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in commercial products. OpenCV (Open Source Computer Vision Library) is an open-source computer vision and machine learning software library. Official documentation can be found here.
And lastly Pyzbar, a python library that will help us read the barcode and QR codes. OpenCV is a well-known library, especially when working with computer vision projects. Pillow library is also known as PIL, which stands for Python Image Library. In this step, we will install the following three libraries: Pillow, OpenCV and Pyzbar. For this project, I recommend using a regular code editor instead of a Jupyter notebook. We will start by installing the libraries that we will need for this project and then we will start programming. Today, we will create our own reader, without losing any time let’s get started! You will see a link show up, it’s very simple to use. Turn on your phone’s camera and show the featured image of this article. If you are wondering how barcode and QR code readers work, let’s do a quick real-life practice. Isn’t that really cool? Table of Contents: And one more thing that I like about them is they can be part of the physical world and still connects us to the internet world. The fun part about them is we can’t really tell what they are storing until we scan them. I think Barcodes/QR codes are very cool and interesting because they store information in a different format. Today, we will something a little more different and that is barcode and QR code reader. These are great projects to practice your skills.

In my previous posts, I showed how to recognize faces and also how to recognize text in an image using python. This is a great machine learning project to get started with computer vision. In this post, I will show you how to build a barcode and Qr code reader using Python.
