通過命令列下載opencv檔案：
git clone https://github.com/Itseez/opencv.git
git clone https://github.com/Itseez/opencv_contrib.git

安裝依賴項：

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

將opencv_contrib移到opencv資料夾，並在opencv資料夾建立build：mkdir build

進入build資料夾進行編譯：

cmake -D CMAKE_INSTALL_PREFIX=/usr/local -D CMAKE_BUILD_TYPE=Release -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib/modules ..

然後是更加漫長的編譯過程：

make -j8

sudo make install

至此安裝結束

測試opencv：

進入samples：

編譯：cmake .

make

./opencv_example
