2. Qr Code Reader For Microsoft Surface

The QR and Barcode Reader interface allows us to focus from the main screen any code that we have in sight, including bar codes. In a few seconds, the application will read it and refer you to the information it contains inside.

On the other hand, the tool offers us the possibility to share the content in our social networks or access previous codes, that we have scanned, to reread a QR that we already deciphered in the past.

1) Make sure your scanner is an HID (Human Interface Device), and can interact directly with your Mac/PC as an input. The scanner connection with your computer can be based off of either a USB or Bluetooth.

Story

Step 1: Setting Up and Using Python 3 Virtualenv on Mac

· Pip3 isinstalled with Python3

Installation

To install virtualenv via pip run:

Usage

Creation of virtualenv:

Activate the virtualenv:

Deactivate the virtualenv:

Step 2: Install OpenCV 3 for Python on Mac

1. Install and update homebrew

2. Tap homebrew-bio

3. Install OpenCV with homebrew including Python 3

4. Change into the OpenCV directory

Since weinstalled OpenCV with Homebrew, the package was should be listed in homebrew'sCellar (/usr/local/Cellar/) To see what's in the Brew Cellar, do this:

Now, let's gointo the opencv directory.

In my case, the numbers 3.3.0_3 and 3.3.1_1 are different versions of OpenCV. This is a goodthing. You'll want the highest version number listed here, in my case it's 3.3.1_1

Awesome. Thisis the OpenCV Version we want to use. We're very close to getting the cv2.<version>.so we need.

5. Find the cv2.<version>.so file in OpenCV

Okay, so wehave the OpenCV version we're going to use and where it's located. Now we needto link it to our version of Python.

· What Python version are you using?

I have Python 3.6 and Python 2.7 installed on my system. If I want both versionsto have OpenCV, I can. I'll just need to add the correct cv2.<version>.so to your Python's site packages. We'll do thispart in the next step. In the meantime, let's get the cv2.<version>.so for each version of Python. You can installwhatever version you want.

Get the Python 3.6 cv2.<version>.so file path:

OpenCV Python3.6 Path: /usr/local/Cellar/opencv/3.3.1_1/lib/python3.6/site-packages/cv2.cpython-36m-darwin.so

Get the Python 2.7 cv2.<version>.so file path:

OpenCV Python2.7 Path: /usr/local/Cellar/opencv/3.3.1_1/lib/python2.7/site-packages/cv2.so

Add OpenCV to Virtualenvs

All you haveto do is add the cv2.<version>.so to your virtualenv's site-packages. Example:

6. Test OpenCV Installation

Step 3: OpenCV and Python Webcam Quick Test

Create a Python file, say camera-test.py containing:

Now run:

You should see two images from your webcam--one in gray scale, one in color just like the one above, albeit with your face!.

To quit, hit the key q 'on' the video window(s) to stop thecamera.

Step 4: Installing ZBar (with Python Bindings) for Barcode Decoding

Installing ZBar for Ubuntu or Raspbian

Installing ZBar for Ubuntu can be accomplished with the following command:

$ sudo apt-get install libzbar0

Installing ZBar for macOS

Installing ZBar for macOSusing brew is equally as easy (assuming you have homebrew installed):

$ brew install zbar

Install pyzbar

Now that I have a Python 3 virtual environment named barcode on my machine, I activated the barcode environment (yours might have a different name) and installed pyzbar:

An OpenCV barcode and QR code scanner with ZBar

Shell

$ workon barcode$ pip install pyzbar

If you are not using a Pythonvirtual environment you can just do:

An OpenCV barcode and QR code scanner withZBar

Python

$ pip install pyzbar install numpy $pip install numpy

Now match for OpenCV + ZBar + Python barcode scanner project! Press q to quit
