1.安装 opencv 所需依赖包

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get -y install libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libtiff5-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libxine2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev 
 

2.下载 opencv

git clone https://github.com/Itseez/opencv.git
git clone https://github.com/Itseez/opencv_contrib.git

 

3.创建并进入 build 目录,执行 cmake 生成 makefile 文件

$ cd ~/opencv
$ mkdir build
$ cd build/
$ sudo cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH= ..

$ sudo make -j8

$sudo make install

 

使用pkg-config --modversion opencv可以查看opencv版本
