PYTHON QR CODE READER LIBRARY HOW TO

After properly configuring Zbar and OpenCV, I will show how to use them to scan the barcode and QR code on an image.The Zbar library will be used with OpenCV to scan barcodes and QR codes.

In the first part, I will teach you how to install the Zbar Library (Python binding).

This paper is mainly divided into four parts. Moreover, I will also show how to deploy our barcode QR code scanner to raspberry pie!!Д¬reate a barcode and QR code scanner with OpenCV and ZBar In this article, I will teach you how to read bar codes and QR codes with OpenCV and Zbar. The library Zbar has also derived many variants, of which pyzbar is my favorite. In fact, the whole process is quite simple and clear. OpenCV can then perform further image processing and display the results. Zbar then decodes the barcode or QR code. After we get the image or video frame, we can transfer it to the special barcode decoding library in Python, such as Zbar. However, OpenCV can speed up the process of reading barcode and QR code, including loading images from the hard disk, grabbing new frames from the video stream and processing them.

Recently, a friend asked me if there are any modules in OpenCV that can directly identify bar codes and QR codes. Finally, he deployed it on raspberry pie and successfully made a practical bar code & QR code scanning device. Computer vision expert Adrian roserock recently shared how to write a scanning program that can recognize QR code and bar code in real time with the help of OpenCV and Zbar.
