Always good practice to update everything before you install stuff: sudo apt-get update sudo apt-get upgrade sudo rpi-update 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
We need to install some packages that allow OpenCV to process videos: sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
We need to install the GTK library for some GUI stuff like viewing images. sudo apt-get install libgtk2.0-dev
We need to install some other packages for various operations in OpenCV: sudo apt-get install libatlas-base-dev gfortran
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
Now we can install NumPy - a python library for maths stuff - needed for maths stuff. sudo pip install numpy
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
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
