先follow這篇文章裝一些必須庫，然後再回來裝v3.2.0

git clone https://github.com/opencv/opencv.git
cd opencv
git checkout 3.2.0
cd ..

OpenCV把一些還不成熟、尚未完整測試的實(shí)做放在另一個opencv_contrib，待成熟且受大眾歡迎後才會收入主要repo。雖說如此，它卻內(nèi)含許多state-of-art的算法，怎麼能錯過呢？

git clone https://github.com/Itseez/opencv_contrib.git
cd opencv_contrib
git checkout 3.2.0

cd {path_to_opencv}
mkdir build
cd build
cmake -DCUDA_CUDA_LIBRARY=/usr/local/cuda/lib64/stubs/libcuda.so\
      -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/modules \
      -D BUILD_EXAMPLES=ON  ..
make -j8
sudo make install
sudo ldconfig

ps. OpenCV 3.1.0與CUDA 8有些相容性問題，建議直接用3.2.0

檢查安裝

$ opencv_version
> 3.2.0
