本文记录ubuntu下安装opencv过程，步骤来自 opencv官网

1、安装opencv所需的库（编译器、必须库、可选库）

转载请说明 [http://www.cnblogs.com/llxrl/p/4471831.html][http_www.cnblogs.com_llxrl_p_4471831.html]

GCC 4.4.x or later  
CMake 2.6 or higher  
Git  
GTK+2.x or higher, including headers (libgtk2.0-dev)  
pkg-config  
Python 2.6 or later and Numpy 1.5 or later with developer packages (python-dev, python-numpy)  
ffmpeg or libav development packages: libavcodec-dev, libavformat-dev, libswscale-dev  
\[optional\] libtbb2 libtbb-dev  
\[optional\] libdc1394 2.x  
\[optional\] libjpeg-dev, libpng-dev, libtiff-dev, libjasper-dev, libdc1394-22-dev

1 [compiler] sudo apt-get install build-essential
    2 [required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
    3 [optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

2、从官网下载最新opencv源码（2.4以上）

[http://sourceforge.net/projects/opencvlibrary/][http_sourceforge.net_projects_opencvlibrary]

或者github

3、编译opencv

将opencv放至任意目录，解压

unzip opencv- 3.0. 0-rc1. zip

创建编译目录，编译

cd ~/opencv-3.0.0-rc1
    mkdir release
    cd release
    cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
    make
    sudo make install

4、测试opencv

1) 创建工作目录

mkdir ~/opencv-lena  
cd ~/opencv-lena  
gedit DisplayImage.cpp  
2) 编辑如下代码

#include <stdio.h>
    #include <opencv2/opencv.hpp>
    using namespace cv;
    int main(int argc, char** argv )
    {
      if ( argc != 2 )
      {
        printf("usage: DisplayImage.out <Image_Path>\n");
        return -1;
      }
      Mat image;
      image = imread( argv[1], 1 );
      if ( !image.data )
      {
        printf("No image data \n");
        return -1;
      }
      namedWindow("Display Image", WINDOW_AUTOSIZE );
      imshow("Display Image", image);
      waitKey(0);
      return 0;
    }

3) 创建CMake编译文件

gedit CMakeLists.txt

写入如下内容

cmake_minimum_required(VERSION 2.8)
    project( DisplayImage )
    find_package( OpenCV REQUIRED )
    add_executable( DisplayImage DisplayImage.cpp )
    target_link_libraries( DisplayImage ${OpenCV_LIBS} )

4) 编译

cd ~/opencv-lena
    cmake .
    make

5) 执行

此时opencv-lena文件夹中已经产生了可执行文件DisplayImage，下载lena.jpg放在opencv-lena下，运行

./DisplayImage lena.jpg

6) 结果
