Now only thing left is sym-link the cv2.so file into site-packages directory of cv environment $ cd ~/.virtualenvs/cv/lib/python2.7/site-packages/ Verify this by using this $ ls -l /usr/local/lib/python2.7/site-packages After completing step 17 your opencv bindings should be in /usr/local/lib/python-2.7/site-packages.

If it's compiled without any error, install it on raspberry pi using: $ sudo make installġ8. Go to opencv 3.0 folder then modules then inside videoio go to src and replace the cap_ffpmeg_impl.hpp with this file After lot of search i found the solution. In my case 'make' thrown me one error which was related to ffpmeg. This is going to take a while so u can let this run overnight $ make Now build is setup, run make to start the compilation process. D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.0.0/modules \ġ7. Now compile and install opencv and make sure u are in cv virtual environment by using this command $ workon cvĪnd then setup up the build using Cmake $ cd ~/opencv-3.0.0/ This will take atleast half an hour so u can have some coffee and sandwiches $ pip install numpyġ6. Now create a python virtual env named cv $ mkvirtualenv cvġ5. Now source your ~/.profile to reload the changes $ source ~/.profileġ4. Source /usr/local/bin/virtualenvwrapper.sh After that installation, open ~/.profile $ nano ~/.profileĪnd add these lines to bottom of the file # virtualenv and virtualenvwrapper Install virtualenv and virtualenvwrapper, this will allow us to create separate, isolated python environments for our future projects $ sudo pip install virtualenv virtualenvwrapper $ sudo rm -rf ~/.cache/pipġ3.
Now install pip $ wget $ sudo python get-pip.pyġ2.

Now opencv and opencv_contrib have been expanded delete their zip files to save some space $ rm opencv.zip opencv_contrib.zipġ1. Downloading the opencv_contrib repository $ wget -O opencv_contrib.zip $ unzip opencv_contrib.zipġ0.

Now download the opencv source and unzip it $ cd ~ĩ. In my case it was already installed but still check $ sudo apt-get install python2.7-devĨ. Now install python 2.7 if it's not there. Optimization packages $ sudo apt-get install libatlas-base-dev gfortranħ. Install GTK dvelopment $ sudo apt-get install libgtk2.0-devĦ. Video I/O packages $ sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev $ sudo apt-get install libxvidcore-dev libx264-devĥ. Now grab the necessary image I/O packages $ sudo apt-get install libjpeg-dev libtiff5-dev libjasper-dev libpng12-devĤ. Then install developer tools $ sudo apt-get install build-essential cmake pkg-configģ.

Everytime you start any new installation it's better to upgrade existing packages $ sudo apt-get update $ sudo apt-get upgradeĢ.
After boot process open terminal and follow the steps to install opencv and setting up virtual environment for opencvġ.
