1. 安裝編譯依賴的軟件包
# 安裝讀寫不同圖片類型的庫: sudo apt-get install libjpeg8-dev libtiff4-dev libjasper-dev libpng12-dev # 安裝讀取視頻格式的庫: sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev # 安裝GTK庫以使用OpenCV的GUI: sudo apt-get install libgtk2.0-dev # 安裝用來優化一些OpenCV內部函數的庫，比如矩陣操作: sudo apt-get install libatlas-base-dev gfortran liblapacke-dev
2. 編譯OpenCV
下載並解壓源碼：
wget https://github.com/opencv/opencv/archive/3.2.0.tar.gz -O opencv.tar.gz wget https://github.com/opencv/opencv_contrib/archive/3.2.0.tar.gz -O opencv_contrib.tar.gz tar zxf opencv.tar.gz tar zxf opencv_contrib.tar.gz
編譯：
cd opencv-3.2.0
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_C_EXAMPLES=OFF \
-D INSTALL_PYTHON_EXAMPLES=OFF \
-D WITH_IPP=OFF \
-DBUILD_opencv_dnn=OFF \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv/opencv_contrib-3.2.0/modules \
-D BUILD_EXAMPLES=OFF ..
make -j4 # 編譯時間好長啊，這還是四核一起編譯呢
安裝
編譯沒有出錯的話，就可以安裝了：
sudo make install sudo ldconfig
以上命令會安裝OpenCV的python模塊到:
(py3.6) veelion@gtx:~/opencv/opencv-3.2.0/build$ ls /usr/local/lib/python3.6/site-packages/ cv2.cpython-36m-x86_64-linux-gnu.so
把以上.so文件鏈接到py3.6虛擬環境下：
(py3.6) veelion@gtx:~$ cd ~/.virtualenvs/py3.6/lib/python3.6/site-packages/ (py3.6) veelion@gtx:~/.virtualenvs/py3.6/lib/python3.6/site-packages$ ln -s /usr/local/lib/python3.6/site-packages/cv2.cpython-36m-x86_64-linux-gnu.so cv2.so
測試OpenCV的安裝
