mac osx 下安装opencv

1.安装homebrew

网上方法很多，自行搜索

2.安装cmake

sudo brew install cmake

 3.下载opencv源代码

wget https://github.com/Itseez/opencv/archive/2.4.13.zip

 4.解压安装

unzip 2.4.13.zip
cd opencv-2.4.13/
mkdir build
cd build/
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON -D BUILD_EXAMPLES=ON ..
make
sudo make install

 5.将cv2.so文件链接到python的site-packages目录

sudo ln -s /usr/local/lib/python2.7/site-packages/cv2.so /Library/Python/2.7/site-packages/

 6.python里测试

>>> import cv2
>>> print cv2.__version__
2.4.13

 另：homebrew 可以直接安装opencv,没有测试，这里仅供参考：

brew update
brew tap homebrew/homebrew-science
brew install opencv
