OpenCV for Pi

A pre-compiled binary of OpenCV for the Raspberry Pi. It is available in a ".deb" package and will save you countless hours not having to compile it yourself. This may or may not stay updated as I have to manually compile each version. I will try to make available most major versions. This was compiled on a Raspberry Pi 3 Model B+ running raspbian jessie. This version was built with TBB which enables automagic multithreading in many OpenCV algorithms.

Instructions

0. Always good practice to update everything before you install stuff:

sudo apt-get update
sudo apt-get upgrade

1. We need to install some packages that allow OpenCV to process images:

sudo apt-get install libtiff5-dev libjasper-dev libpng12-dev

If you get an error about libjpeg-dev try installing this first:

sudo apt-get install libjpeg-dev

2. We need to install some packages that allow OpenCV to process videos:

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

3. We need to install the GTK library for some GUI stuff like viewing images.

sudo apt-get install libgtk2.0-dev

4. We need to install some other packages for various operations in OpenCV:

sudo apt-get install libatlas-base-dev gfortran

5. We need to install pip if you haven't done so in the past:

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

6. Now we can install NumPy - a python library for maths stuff - needed for maths stuff.

sudo pip install numpy

7. Download and install the file from this repo called "latest-OpenCV.deb".

wget "https://github.com/jabelone/OpenCV-for-Pi/raw/master/latest-OpenCV.deb"
sudo dpkg -i latest-OpenCV.deb

8. Test it installed correctly by doing the following: Open a python shell

python

Run the following commands, it should return the same version you installed.

import cv2
cv2.__version__

9. Have fun with OpenCV and open an issue on GitHub if you have any problems or I forget to update it. pyimagesearch is a great resource to get started!
