OpenCV 2.3.1 Python Bindings installation on Windows 7

Today I searched several post about how to install OpenCV Python bindings on Windows 7. And I found many of them made it too complicated.

Here is my simple solution. Many thanks to Christoph Gohlke, Laboratory for Fluorescence Dynamics, University of California, Irvine, his work makes many Python modules be easy to be installed on Windows.

Simple steps:

  1. Install numpy for python, as OpenCV 2.3.1 needs this. normally choose the MKL version and the relevant python version and OS architecture( x86 or amd64)
  2. Install OpenCV , choose the relevant python version and OS architecture( x86 or amd64) as numpy
  3. The tricky part: as opencv 2.3.1 has been evolved to cv2, the old cv functions has been moved to cv2.cv. The workaround is create a cv.py file with
    from cv2.cv import *
    
  4. Copy this cv.py file under directory %PYTHON_HOME%\Lib\site-packages
  5. Now you can import cv to wrote OpenCV code. Have fun:)
