1. Introduction
In this post, we’ll detail how to install Python and OpenCV on a Windows 7 system.
2. Python installation
2.1 Download / Installation
At this time, OpenCV 3.0 is not fully ready to run with Python 3.X, we’ll download Python 2.7 from here and proceed to the installation.
You will also need to install some libraries :
– Numpy : package for scientific computing with Python.
– Matplotlib : Matplotlib is a python library for making publication quality plots.
Everything should be installed in C:/Python27/
2.2 Test
To test, start the Python IDLE.
Load numpy :
import numpy
“Hello World” with Python :
print("Hello World !")
3. OpenCV installation
3.1 Download / Installation
You can download OpenCV from the official website. Then start the setup and extract all the files to a temporary file in your documents :
OpenCV installation is done by copying cv2.pyd from opencv\build\python\2.7\x86 to C:\Python27\Lib\site-packages.
3.2 Test
One this is done, we load the OpenCV library :
import cv2
Everything is ready !
