Opencv Offical Tutorial

1. Download opencv src to /usr/local/src/opencv
   • cd /usr/local/src
   • git clone https://github.com/Itseez/opencv.git
2. Download opencv_contrib to /usr/local/src/opencv_contrib
   • cd /usr/local/src
   • git clone https://github.com/Itseez/opencv_contrib
3. make directory for compile
   • mkdir build
   • cd build

4. Compile opencv

   • Configuring

     cmake -D CMAKE_BUILD_TYPE=RELEASE \
     -D OPENCV_EXTRA_MODULES_PATH=/usr/local/src/opencv_contrib/modules \
     -D CMAKE_INSTALL_PREFIX=/usr/local \
     -D PYTHON_INCLUDE_DIR=/usr/local/anaconda/include/python2.7/ \
     -D PYTHON_LIBRARY=/usr/local/anaconda/lib/libpython2.7.so \
     -DPYTHON2_PACKAGES_PATH=/usr/local/anaconda/lib/python2.7/site-packages \
     -DBUILD_SHARED_LIBS=OFF \
     -D BUILD_DOCS=ON \
     -D BUILD_TESTS=OFF \
     -D BUILD_PERF_TESTS=OFF \
     -D BUILD_EXAMPLES=OFF ..

   • Optional Flags

     • -D BUILD_opencv_python3=OFF

5. Installing

   • make && make install
6. Check if cv2.so is in Python packages directory
   • ls /usr/local/anaconda/lib/python2.7/site-packages/cv2.so
   • If no cv2.so there, copy from PYTHON_PACKAGES_PATH:
     • cp /usr/local/lib/python2.7/site-packages/cv2.so /usr/local/anaconda/lib/python2.7/site-packages
7. Validate opencv-python
   • python -c "import cv2; print cv2.__version__"
