Hello World from OSS Silicon Valley

_ Prerequisite

• Raspbian installation (You can refer HowToUse/Raspbian/WHEEZY) or
• Ubuntu Server installation (You can refer HowToUse/UbuntuServer/14.04

_ Install&Setup

_ Raspbian WHEEZY

Step.1

Update existing modules.

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo rpi-update
$ sudo reboot

Step.2

Install required modules for OpenCV.

$ sudo apt-get install build-essential git cmake pkg-config
$ sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev
$ sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
$ sudo apt-get install libxvidcore-dev libx264-dev
$ sudo apt-get install libgtk2.0-dev
$ sudo apt-get install libatlas-base-dev gfortran

Step.3

Install Python

$ sudo apt-get install python2.7-dev python3-dev
$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python get-pip.py
$ pip install numpy

Step.4

Download OpenCV

$ mkdir <OpenCV Install directory>
$ cd <OpenCV Install directory>
$ wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.1.0.zip
$ unzip 3.1.0.zip
$ wget -O opencv_contrib.zip https://github.com/Itseez/opencv_contrib/archive/3.1.0.zip
$ unzip opencv_contrib.zip

Step.5

Compile OpenCV

$ cd opencv-3.1.0
$ mkdir build
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=<OpenCV Contrib Path>/modules -D BUILD_EXAMPLES=ON ..

_ When you install OpenCV 3.0, you can set INSTALL_C_EXAMPLES as "ON".

Example

$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=~/vendor/opencv_contrib-3.1.0/modules -D BUILD_EXAMPLES=ON ..

If compilation terminated successfully, you will see something like the following standard out.

--   Python 2:
--     Interpreter:                 /usr/bin/python2.7 (ver 2.7.3)
--     Libraries:                   /usr/lib/libpython2.7.so (ver 2.7.3)
--     numpy:                       /usr/lib/pymodules/python2.7/numpy/core/incl                                                                                        ude (ver 1.6.2)
--     packages path:               lib/python2.7/dist-packages
--
--   Python 3:
--     Interpreter:                 /usr/bin/python3 (ver 3.2.3)
--     Libraries:                   /usr/lib/libpython3.2mu.so (ver 3.2.3)
--     numpy:                       /usr/lib/python3/dist-packages/numpy/core/in                                                                                        clude (ver 1.6.2)
--     packages path:               lib/python3.2/dist-packages

$ make -j4
$ sudo make install
$ sudo ldconfig

Then you can see if OpenCV has been installed successfully with the following command.

$ python
>>> import cv2
>>> cv2.__version__
'3.1.0'

_ Ubuntu Server 14.04

Step.1

Update modules

$ sudo apt-get update

Step.2

Install required modules for OpenCV.

$ sudo apt-get install build-essential git cmake
$ sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev
$ sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
$ sudo apt-get install libxvidcore-dev 
$ sudo apt-get install libgtk2.0-dev
$ sudo apt-get install libatlas-base-dev gfortran

_ libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev, libpng12-dev, libx264-dev should have been installed

Step.3

Install Python

$ sudo apt-get install python2.7-dev python3-dev
$ wget https://bootstrap.pypa.io/get-pip.py
$ sudo python get-pip.py
$ pip install numpy

Step.4

Download OpenCV

$ mkdir <OpenCV Install directory>
$ cd <OpenCV Install directory>
$ wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.1.0.zip
$ unzip opencv.zip
$ wget -O opencv_contrib.zip https://github.com/Itseez/opencv_contrib/archive/3.1.0.zip
$ unzip opencv_contrib.zip

Step.5

$ cd opencv-3.1.0
$ mkdir build
$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=OFF -D INSTALL_PYTHON_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=<OpenCV Contrib Path>/modules -D BUILD_EXAMPLES=ON ..

--     packages path:               lib/python3.2/dist-packages

$ make -j4
$ sudo make install
$ sudo ldconfig

Then you can see if OpenCV has been installed successfully with the following command.

$ python
>>> import cv2
>>> cv2.__version__
'3.1.0'
