OpenCV Setup

Copy OpenCV Repo

Get OpenCV 3.3 build from GitHub

cd ~
wget https://github.com/opencv/opencv/archive/3.3.0.zip
unzip 3.3.0.zip
mv opencv-3.3.0/ opencv
cd opencv

Build OpenCV

cd ~/opencv
$ mkdir build
$ cd build
$ sudo cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

Compile OpenCV

1	`make` `-j7`

If you run out of disk space on your VM check out the little guide on extending your Virtual Disk

Install OpenCV

sudo make install
sudo ldconfig

Test

python

import cv2
cv2.__version__

The above should return 3.3.0 (The OpenCV Version you installed)

Exit python interpreter and return to terminal

exit()
