编译opencv与python

• 从github上下载opencv对应版本代码， 假设位于/home/opencv
  <pre>
  cd /home/opencv
  mkdir build
  cd build
  cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..
  make -j8
  sudo make install
  </pre>
• 到这一步为止，opencv的python库被安装在/usr/lib/python2.7/dist-packgages

在virtualenv中使用cv2

• 将/usr/local/lib/python2.7/site-packages中的cv2.so和cv.py复制到对应的virtualenv的python目录的sites-packages中
  <pre>
  cp /usr/loal/lib/python2.7/site-packages/cv2.so ~/tensorflow0.12/lib/python2.7/site-packages
  cp /usr/lib/python2.7/dist-packages/cv.py ~/tensorflow0.12/lib/python2.7/site-packages
  </pre>
