安装OpenCV

准备工作

$ 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

下载OpenCV

$ # Download opencv from github$ git clone https://github.com/opencv/opencv.git$ cd opencv$ # 切换到想要的版本$ git checkout 3.0.0 # OR git checkout 2.4.13

编译OpenCV

$ mkdir release$ cd release$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..$ make -j16$ sudo make install

如果不想编译某个模块，将模块设置为OFF，例如

$ cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_DOCS=ON -D WITH_CUDA=OFF -D BUILD_DOCS=OFF ..
