QR Code reader

This repo using pyzbar library with opencv to read both QR and barcode. However, if you only want to read QRCode, you can simply use the built-in function in openCV (QRCodeDetector).

There are 2 modes in the project:

• stream: real time detect via video
• image: detect on an input image

Detected code will be displayed with a message (text) over the bounding box.

Environment

• Ubuntu 20.04 (runnable on Raspberry Pi)
• Python 3.7

Requirements

• OpenCV
• Pyzbar

IMPORTANT: Remember to install libzbar0 first, otherwise it will get error when running

sudo apt-get install libzbar0
